In the face of global pressures of climates change and biodiversity loss, CWR requires urgent conservation attention. As a first step toward a national strategy for the conservation of CWRs, we present an inventory of taxa occurring in Brazil, with suggested prioritization of species based on potential value in crop improvement. The CWR checklist comprised 3652 taxa among 112 genera, and after applying the prioritization criteria, 289 CWRs were prioritized. The prioritized CWRs are related to crops of regional, national, and global importance such as cassava (Manihot esculenta Crantz), sugarcane (Saccharum officinarum L.), coffee (Coffea arabica L. and Coffea canephora Pierre ex A. Froehner), cotton (Gossypium hirsutum L.), rice (Oryza sativa L.), orange (Citrus spp.), beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), potato (Solanum tuberosum L.), and cocoa (Theobroma cacao L.). More than half of the prioritized CWRs (50.86%) are endemic, and 28.03% are nationally endangered. A subsequent prioritization was also carried out using the criteria of socioeconomic value of the related crop and endemism, with 95 taxa being prioritized. The production of the first CWR inventory for Brazil is an important tool for planning conservation actions as part of a national strategy to maintain food security.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, efforts to improve sesame for higher fiber have been constrained by limited knowledge of the genetic factors underlying this trait. In this study, we identified a strong correlation between fiber and sugar content, both of which are significantly influenced by genetic factors. A large-scale analysis of 222 sesame germplasm resources revealed genome-wide single nucleotide polymorphism (n = 1,535,018), insertions and deletions (InDels; n = 325,371), and structure variations (SVs; n = 29,028). Linkage disequilibrium and genome-wide association studies identified an InDel quantitative trait locus targeting the SiLAC3 gene, which caused a gene frameshift mutation significantly associated with both sugar and dietary fiber traits. Furthermore, a 1201-bp deletion SV in the coding and 3′ untranslated regions of the SiXTH30 gene was associated with high fiber content. Notably, two accessions (CX150 and CX546) with pyramiding favorable alleles of these two mutated genes exhibited a significant increase in fiber content compared to accessions with only one favorable allele. We also found two candidate genes highly expressed during the early and middle stages of seed development, both of which have been previously reported to play important roles in cell wall fiber content. In conclusion, our findings highlight two key fiber-associated candidate genes, which could serve as valuable resources for molecular breeding aimed at increasing fiber content in sesame seeds.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the seedling and vegetative stage, cold stress causes curled leaves, fewer tillers, retarded growth, chlorosis, and necrosis. Due to the significance of this trait, exploring the wealth of genetic resources from a wider pool of germplasm to identify new sources of tolerance will be a crucial step. Toward this goal, we performed a genome-wide association study (GWAS) on a novel diversity panel of 238 rice accessions using the 7K SNP Cornell-IR LD Rice (C7AIR) single nucleotide polymorphism (SNP) array. The experiment was conducted in controlled growth conditions, and rice accessions were evaluated for seven traits and four indices, which were recorded at three different time points, that is, before cold treatment, after cold treatment, and post-recovery phase. A total of 77 significant GWAS-quantitative trait loci (QTLs) were identified for 21 cold tolerance and related traits of interest. Out of these, 34 were detected after cold stress, and 43 were detected during the post-recovery phase. A total of 42 QTL regions were significant at false discovery rate (FDR) < 0.001 and −log10(p-values) > 5. In addition, 31 novel GWAS-QTLs, three colocalized GWAS-QTL hotspots, and eight colocalized GWAS-QTLs for two traits sharing the same genomic location were also identified. The results of this study may help in further elucidating the molecular mechanisms underlying cold tolerance as well as aid in developing climate-smart rice varieties for chilling stress conditions.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted field studies to test the response of the combined organic and inorganic N management on soil properties, N use efficiency (NUE), and wheat (Triticum aestivum L.) production under different tillage intensities in a semiarid climatic conditions. The experiment was designed on a split plot arrangement consisting of three tillage intensities: one time ploughing (T1), two times ploughing (T2), and three times ploughing (T3) with the interval of 10 days in the main plots. Seven organic–inorganic N management strategies using urea:farm yard manures were NM1 0:0, NM2 100:0, NM3 80:20, NM4 60:40, NM5 40:60, NM6 20:80, and NM7 0:100 in the subplots. Results revealed that soil organic carbon (SOC) and labile organic carbon contents were significantly higher in the NM6 treatment under the T3 tillage intensity. Higher soil N and potassium (K) were found in NM5 under the T3 tillage intensity, whereas the soil phosphorus (P) was the highest in NM6 plot. The activities of soil invertase and urease enzymes were also significantly higher in the NM6 treatment under T3 tillage intensity. Wheat growth and yield, N-uptake and NUE were the highest in T3 with NM6 management strategy.

Our objective was to identify and map additional stem rust resistance genes in Waldron through aneuploid analysis, allelism tests, and linkage with molecular markers. Four lines, WDR-A1, WDR-C2, WDR-D1, and WDR-E4, each carrying a single stem rust resistance gene from Waldron, were crossed to appropriate genetic stocks. Telosomic analysis failed to confirm the previously reported location of SrWDR-C2 to chromosome 7A. Monosomic analysis, allelism tests, and multi-pathotype seedling tests indicated that the genes in WDR-A1 and WDR-D1 were Sr18 and Sr9g, respectively. Telosomic analysis, allelism tests, and marker analysis of WDR-E4 indicated that SrWld1 should be reassigned from chromosome 2A to 2BL. When families were tested with races LBBLB, TMLKC, and TPPKC, co-segregation of resistance was not observed. This suggests that inheritance of the SrWld1 phenotype was quantitative and that additional studies are needed on the inheritance of SrWld1. When results from this study were combined with previous studies, the stem rust resistance genes in Waldron are identified as Sr9g, Sr11, Sr18, Sr41, SrWld1, and SrWld2.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RNA was extracted from embryos in seeds harvested at physiological maturity and dried for 1 week. We also assessed expression levels of known quantitative trait locus genes linked to seed dormancy. In H602 and H602 × KNG, 417 genes showed significantly higher expression than KNG and KNG × H602, with 14 GO terms enriched, including stress response and sugar metabolism. Genes involved in DNA repair were also enriched for highly expressed genes in H602 than KNG. In KNG and KNG × H602, 198 genes showed significantly higher expression than H602 and H602 × KNG, with 60 GO terms enriched, including development and auxin transport.

However, the regulation of heading date and its impact on other agronomic traits remain to be fully understood. In this study, we identified a mutant named late-flowering and big panicle 1 (lbp1) in rice; we surveyed the growth and yield traits in lbp1. Changes in gene expression between lbp1 and wild type (WT) were determined by RNA-seq. lbp1 exhibits delayed heading of 1 month and enhancements in various agronomic traits. Compared with WT plants, lbp1 showed 336.9% higher biomass production, 27.7% longer panicle length, 41.2% higher grain numbers, 29.4% and 56.6% more primary and secondary branch numbers, and an overall 58.7% higher grain yield. Map-based cloning pinpointed that the mutant phenotypes stemmed from a mutation in the early heading date 1 (Ehd1) gene. Through RNA-seq and quantitative reverse transcription-polymerase chain reaction analysis, we observed significantly lower expression levels of heading date 3a (Hd3a) and RICE FLOWERING LOCUS T 1 (RFT1) in lbp1 compared to WT plants. Additionally, the expression levels of several MADS-box genes were downregulated in the mutant. Our findings indicate that negative regulation of the Ehd1-Hd3a/RFT1 pathway leads to delayed heading, enhanced biomass production, and increased grain yield. This discovery presents an effective breeding strategy for developing new japonica rice varieties with prolonged vegetative growth periods suitable for cultivation in southern China and other low-latitude regions.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rising photosynthesis is being proposed as a promising avenue to increase wheat yields, but evidence for this is conflicting across studies. To test the viability of this hypothesis, here we report a systematic and quantitative literature review examining the association between historic yield increases due to breeding that occurred over 129 years (1890–2019) across the globe and light-saturated photosynthesis (Asat) for 273 wheat commercial varieties released to farmers in five continents. A positive and highly significant relationship between trial-corrected grain yield and cultivars’ year of release (YOR) was found globally (R2 = 0.56), with an annual rate of yield increase of 0.84%. Trial-corrected seed-fill Asat increased globally at a pace of 0.58% year−1, and this association was the strongest among the examined four phenological stages. Detrended (from YOR), trial-corrected grain yield and Asat were found to be correlated, with this association being significant only during seed-fill. The analysis also suggests that historical yield gains may also have been achieved by an increase in water uptake during seed-fill, but it points to the need for more standardized protocols for measuring gas exchange in such vintage/era studies. Overall, these insights indicate that breeding for higher wheat yields was accompanied by physiological alterations to improve Asat and, possibly, increase water use during the critical seed-fill period, two traits that are also likely to enhance wheat climate resilience.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143191738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examined the barley (Hordeum vulgare) and rice (Oryza sativa) orthologs of TaMFT-3A. RNA in situ hybridization showed that the rice and barley orthologs are primarily expressed in the scutellum, indicating that these three MFT2 genes have a common expression pattern during seed development. Analysis of the cis-acting regulatory elements of their promoter sequences showed that the promoters share eight seed-specific cis-acting RY motifs and a binding site for B3-domain transcription factors, the main regulators of seed development. Moreover, we found tandemly repeated A-box motifs in the promoters of TaMFT on chromosomes 3B and 3D, but a single motif on chromosome 3A, possibly explaining why the A-box motif mutation in TaMFT-3A increases dormancy. Our immunohistochemical observations of green fluorescent protein (GFP)-tagged MFT2 in transgenic rice plants detected rice MFT2 (OsMFT2)-GFP in the scutellum and the scutellar epithelium, which is an important tissue for initiating germination.

Morphologically, hairy vetch is highly variable, but this study found statistically significant differences between smooth and hairy vetch in visual pubescence scores, plant maturity, and calyx lobe lengths. We used a panel of single sequence repeat (SSR) markers to assign cultivars and breeding materials to the two species and found that many commercial cultivars are smooth vetch. Interestingly, the SSR panel indicated that woollypod vetch (Vicia dasycarpa Ten.) is a subpopulation of hairy vetch. Based on an elastic net model trained with multi-site trial results from >35 site-years, smooth vetch is not winter hardy in the northern United States but has superior performance relative to hairy vetch in the south-central and Pacific Northwest United States. Specifically, smooth vetch has greater performance in environments with mild winters, cool spring temperatures, or low clay soils.
