Research has shown that alternate wetting and drying (AWD) of rice fields, rather than maintaining a continuous flood (FLD), can lower concentrations of both total As (tAs) and the more toxic inorganic As (iAs) in milled rice. Unfortunately, irrigation management that oxidizes the soil can potentially result in higher Cd concentrations. This 2-year study tested the hypothesis that AWD with two short drains is better than a single mid-summer drain (MSD) or flood (FLD) on rice yield, element content, and various starch quality attributes. The results revealed that AWD did not reduce yield compared to MSD and FLD and that AWD and MSD resulted in a negligible milling quality penalty compared with FLD. AWD had the added benefit of significantly reducing tAs and iAs in grains compared with FLD and MSD. AWD did not increase grain Cd in brown rice when compared with FLD and caused either no consequential change or a desirable increase in 10 other elements. Protein concentration was reduced by only half a percentage point, and starch quality attributes were minimally impacted as well. This study highlights the importance of water management practices in minimizing accumulation of hazardous elements such as As and Cd in rice grains while enabling sustainable rice production with conventional yields and cooking quality attributes.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143762118","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}

BSA-Seq of both two-type lines detected one candidate gene BnaA08g26080D on the chromosome A08 in common. By integrating the genetic maps of Mf/Ms and Ms/ms locus, the fertility locus of Shaan-GMS was located in the overlapping region on the A08 chromosome containing 14 genes.

As a result, two genes (BnaA08g25920D and BnaA08g25870D) showed DNA sequence variation among male sterile plants (MsMs), fertile plants (msms), and restorer plants (MfMf) of Shaan-GMS. The candidate gene association analysis indicated that DNA variations in the BnaA08g25870D had no relationship with male fertility in a panel of 88 rapeseed lines, therefore, BnaA08g25920D is the candidate for the male sterile gene.

Substantial genetic diversity was observed within and among species. In addition, substantial genetic variation was found for morphological and reproductive traits and the reliability for those traits was moderate to high (𝑖2 = 0.38–0.83).

In high-latitude paddy ecosystems, weedy rice tends to head earlier than accompanied japonica rice. However, the heading allele genes underlying this weedy rice de-domestication, which is crucial for understanding the genetic basis and repeatability of the heading, remain largely unexplored. Therefore, this study aims to investigate the allelic variation of nine heading genes using 46 weedy rice from three areas in northeast China (weedy rice from northeast China [WRNC]) and 32 of their accompanying japonica rice (Oryza sativa L.) varieties. The heading time of WRNC was 3–20 days earlier than that of the accompanying japonica rice. The heading-promotion genotype heading date 1 (Hd1) was the main factor aiding WRNC heading earlier than its accompanying japonica rice. Functional haplotypes of heading date 2 (Hd2), grains height date 7 (Ghd7), and days to heading 2 (Dth2) may affect the early heading of weedy rice from Liaoning, Jilin, and Heilongjiang in northeast China. Phylogenetic tree analysis showed that WRNC is closely related to the cultivated rice in Northeast China and has no direct relationship with southern indica weedy rice. The results showed that some heading genes in the study differentiated during the divergence of indica and japonica rice; these genes in WRNC are not only affected by the differentiation of indica and japonica rice but also by the domestication of cultivated rice, forming an independent heading genotype distinct from northern japonica rice. This serves as a basis for research aimed at improving the heading period of cultivated rice by utilizing traits from weedy rice.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717024","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}

Here, we employed in-context promoter bashing to characterize the proximal upstream regulatory regions of sorghum genes encoding phosphoenolpyruvate carboxykinase bundle sheath (SbPEPCK.BS, SbiTx430.01G455400) and alanine aminotransferase bundle sheath (SbAlaAT.BS, SbiTx430.02G006600), two proteins involved in the PCK C4 pathway.

A 138 bp within the SbPEPCK.BS upstream region and a 1643 bp element within the SbAlaAT.BS upstream region were determined to be important for maintenance of transcription levels. No change in development or various physiological parameters was observed in characterized lineages carrying promoter edits. However, significant changes in seed reserves and a reduction in 100-seed weight were consistently observed, under both greenhouse and field environments, in plants carrying an edit in the promoter of SbPEPCK.BS gene, which were significantly reduced in transcript accumulation for this gene.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699030","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}

Loss of function alleles of Wx result in the endosperm having a waxy appearance, and contain nearly all amylopectin, the highly branched starch polymer. A critical question for commercialization of waxy grain sorghum [Sorghum bicolor (L.) Moench] for applications ranging from food industry to bioenergy crop production is whether hybrids deleteriously affect agronomic traits. A set of six waxy sorghum A-lines was crossed with a set of six R-lines developed by USDA-ARS in Lincoln, NE. The hybrids were grown in two field sites under dryland and irrigated conditions. Both agronomic and grain composition traits were determined. The amylose concentration from all waxy hybrid grain was around 5% compared to wild-type hybrid checks, which had concentrations around 35%. In general, seedling emergence, test weight, and 100-seed weight were lower for wx hybrids than the commercial check. The grain yields for wx hybrid combinations with A lines PI 670136 and PI 672150 (Wheatland wx) or R-line PI 672152 (RTx430 wx) were over 8000 kg ha−1 for several combinations. The A line PI 670136 in combination with five of the R-lines evaluated produced white sorghum grain on tan plants that could be milled into food grade white sorghum flour.

The objective of this research was to assess the effect of N supply on soybean yield components distribution within the canopy. A ‘Full-N’ treatment, which provided the crop with ample N supply, was compared against a ‘Zero-N’ treatment in which the crop relied on soil N and biological N fixation at nine high-yielding irrigated soybean environments in Nebraska, with known levels of N limitation. Soybean seed yield components were determined at every node and grouped into five canopy sections. Seed yield ranged from 4378 to 7314 kg ha−1 across environments and treatments. The greater N availability in the Full-N increased yield by 984 kg ha−1 in comparison to Zero-N; via +253 seeds m−2 (7%) and +16 mg seed−1 (11%). N-induced responses in seed yield occurred in the lower (nodes 0–4), middle (nodes 9–13), and middle-upper sections (nodes 13–18). Seed number and pod number increased in the middle-upper section. Notably, individual seed weight increased in all node sections. The seed number per pod response to N was negligible.

This study assessed the efficacy of novaluron, a recently registered benzoylphenyl urea insect growth regulator which inhibits chitin synthesis in developing larvae, as an alternative to conventional neurotoxic insecticides. Field trial treatments were designed to assess the effect of application timing in relation to population development stages, including peak overwintering adult emergence and early-instar (stem-boring) and late-instar (soil-dwelling) larvae. Novaluron was effective at all timings, even when larvae were not yet present (overwintering adult peak). In laboratory assays, novaluron topically applied to adults reduced the recovery of first-instar larvae by 91%–98% and 0%–43% in 2020 and 2021, respectively. Significant ovicidal activity was also observed with reductions of 67%–85% and 35%–68% in 2020 and 2021 trials, respectively. Females treated with 9.3 L ha−1 novaluron experienced reduced fecundity over 8 weeks (52%), though weekly reductions were only significantly different from controls in the first week after exposure. Novaluron-treated adults resumed oviposition after being transferred to untreated turf, suggesting potential recovery from exposure. These studies demonstrate novaluron's effectiveness against a wide range of larval instars which should facilitate flexible application timing in field settings. However, the transient effects observed on adults in laboratory studies may reduce novaluron's reliability as an adulticide.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"65 2","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/csc2.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660371","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}
