Here we present simET, an open-source software package written in the R programming language. Many concepts involved in crop ETc simulation are condensed into functions in the package. It includes three widely used crop ETc models built on these functions: the single-crop coefficient, double-crop coefficient, and Shuttleworth–Wallace models, along with tools for preparing model data and comparing estimates. SimET supports ETc simulation in crops with repeated growth cycles such as alfalfa, a perennial forage crop that is cut multiple times annually.</p></div>","PeriodicalId":10790,"journal":{"name":"Crop Journal","volume":"11 5","pages":"Pages 1579-1585"},"PeriodicalIF":6.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49803754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many genes involved in chloroplast development have been identified, the mechanisms underlying such development are not fully understood. In this study, a rice (<em>Oryza sativa</em>) mutant exhibiting pale green color and seedling lethality was isolated from a mutant library. The mutated gene was identified as an ortholog of <em>THA8</em> (<em>thylakoid assembly 8</em>) in <em>Arabidopsis</em> and maize. This gene is designated as <em>OsTHA8</em> hereafter. OsTHA8 showed a typical pentatricopeptide repeat (PPR) characteristic of only four PPR motifs. Inactivation of OsTHA8 led to a deficiency in chloroplast development in the rice seedling stage. <em>OsTHA8</em> was expressed mainly in young leaves and leaf sheaths. The OsTHA8 protein was localized to the chloroplast. Loss of function of OsTHA8 weakened the editing efficiency of <em>ndhB-611</em>/<em>737</em> and <em>rps8-182</em> transcripts under normal conditions. Y2H and BiFC indicated that OsTHA8 facilitates RNA editing by forming an editosome with multiple organellar RNA editing factor (OsMORF8) and thioredoxin z (OsTRXz), which function in RNA editing in rice chloroplasts. Defective OsTHA8 impaired chloroplast ribosome assembly and resulted in reduced expression of PEP-dependent genes and photosynthesis-related genes. Abnormal splicing of the chloroplast gene <em>ycf3</em> was detected in <em>ostha8</em>. These findings reveal a synergistic regulatory mechanism of chloroplast biogenesis mediated by RNA, broaden the function of the PPR family, and shed light on the RNA editing complex in rice.</p></div>","PeriodicalId":10790,"journal":{"name":"Crop Journal","volume":"11 5","pages":"Pages 1353-1367"},"PeriodicalIF":6.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49845246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, fewer yield-related quantitative trait loci (QTL) have been reported in peanut than in other staple food crops such as rice (<em>Oryza sativa</em>), wheat (<em>Triticum aestivum</em>), and maize (<em>Zea mays</em>). This study aimed to identify stable major-effect QTL associated with pod yield per plant, hundred-pod weight for double-seeded pods, hundred-seed weight, shelling percentage, and pod number per plant, allowing us to predict candidate genes by means of transcriptome and genome sequencing. To this end, we used a population of recombinant inbred lines comprising 192 F_9:11 families derived from a JH6 × KX01-6 cross to construct a high-resolution genetic map (1705.7 cM) consisting of 2273 polymorphic SNPs, with 0.75 cM (on average) between adjacent SNPs. We identified two high-confidence, yield-related QTL, <em>qHYF_A08</em> and <em>qHYF_B06</em>, explaining 5.78%–31.40% of phenotypic variation and with LOD values of 5.10–24.48, in six environments. <em>qHYF_A08</em> mainly explained the variation in shelling percentage, whereas <em>qHYF_B06</em> explained variation in hundred-pod weight and hundred-seed weight and accounted for 8.77%–31.40% of the variation in effective pod number per plant, pod number per plant, and shelling percentage. We narrowed down <em>qHYF_B06</em> to an 890-kb interval using an advanced mapping population. Transcriptome and genome analyses revealed that only Arahy.129FS0 and Arahy.3R9A5K in the candidate mapping interval were differentially expressed between JH6 and KX01-6, with substantial structural variations in their promoter and coding regions. Genotypes of 208 peanut accessions determined using a diagnostic CAPS marker suggested that the two haplotypes of Arahy.3R9A5K were highly associated with hundred-seed weight and hundred-pod weight; this diagnostic CAPs marker could therefore be useful for selecting high-yielding lines during peanut breeding.

In this study, compensated temperature was integrated into the AquaCrop model to investigate the capability of the compensatory effect to improve assessment of the promotion of maize growth and development by plastic film mulching (PM). A three-year experiment was conducted from 2014 to 2016 with two maize varieties (spring and summer) and two mulching conditions (PM and non-mulching (NM)), and the AquaCrop model was employed to reproduce crop growth and yield responses to changes in NM, PM, and compensated PM. A marked difference in soil temperature between NM and PM was observed before 50 days after sowing (DAS) during three growing seasons. During sowing–emergence and emergence–tasseling, the increase in air temperature was proportional to the compensatory coefficient, with spring maize showing a higher compensatory temperature than summer maize. Simulation results for canopy cover (CC) were generally in good agreement with the measurements, whereas predictions of aboveground biomass and grain yield under PM indicated large underestimates from 60 DAS to the end of maturity. Simulations of spring maize biomass and yield showed general increase based on temperature compensation, accompanied by improvement in modeling accuracy, with RMSEs decreasing from 2.5 to 1.6 t ha⁻¹ and from 4.1 t to 3.4 t ha⁻¹. Improvement in biomass and yield simulation was less pronounced for summer than for spring maize, implying that crops grown during low-temperature periods would benefit more from the compensatory effect. This study demonstrated the effectiveness of the temperature compensatory effect to improve the performance of the AquaCrop model in simulating maize growth under PM practices.</p></div>","PeriodicalId":10790,"journal":{"name":"Crop Journal","volume":"11 5","pages":"Pages 1559-1568"},"PeriodicalIF":6.6,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49803756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a heterozygous plant from a F₇ recombinant inbred line (RIL) population lacking the <em>Yr18</em> gene, a near-isogenic line (NIL) population was developed to map the resistance gene. An all-stage resistance gene, <em>YrAS1676</em>, was identified on chromosome arm 1AL via bulked-segregant exome-capture sequencing. By analyzing a large NIL population consisting of 6537 plants, the gene was further mapped to the marker interval between <em>KA1A_485.36</em> and <em>KA1A_490.13</em>, spanning 485.36–490.13 Mb on 1AL. A total of 66 annotated genes have been reported in this region. To characterize and predict the candidate gene(s), an RNA-seq was performed using NIL-R and NIL-S seedlings 3 days after CYR34 inoculation. Compared to NIL-S plants, NIL-R plants showed stronger immune reaction and higher expression levels of genes encoding pathogenesis-associated proteins. These differences may help to explain why NIL-R plants were more resistant to <em>Pst</em> race CYR34 than NIL-S plants.
