Soybean is highly sensitive to flooding and substantial yield losses are observed due to a cascade of negative physiological responses induced by hypoxia. Hence, there is a pressing need for the development of flood‐tolerant genotypes. This study evaluated the grain yield and seed protein and oil content of 31 soybean genotypes over 2 years under both non‐flooding and flooding conditions, where flooding entailed a 4‐day partial water submergence during the early reproductive growth stages R1/R2. Mixed‐effects linear models were utilized to assess the impact of flood damage scores (FDSs, 1–4 scale) on observed phenotypes, as well as differences in observed phenotypes between tolerant, moderate, and susceptible genotypes across flooding and non‐flooding treatments. No significant impact of FDS was observed for seed protein and oil content. In addition, no significant differences in these phenotypes were observed between flooding and non‐flooding treatments across the various genotype categories. On average, for each unit increase in FDS, grain yield decreased by 432.7 kg ha<jats:sup>−1</jats:sup> (17.4%). Tolerant genotypes experienced roughly 33% yield losses between flooding and non‐flooding treatments, while moderate and susceptible genotypes experienced 44% and 51% yield losses, respectively. The advancements in genomics and phenomics are promising for the identification and incorporation of novel flood‐tolerant alleles through plant breeding, potentially mitigating flooding‐induced yield losses across diverse environmental conditions.","PeriodicalId":10849,"journal":{"name":"Crop Science","volume":"41 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142488748","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}

Lam cultivars, Melinda and Tio Joe, to coinfection with sweet potato chlorotic stunt virus (SPCSV) and sweet potato pakakuy virus (SPPV), employed a comprehensive approach encompassing symptomatology, real-time quantitative polymerase chain reaction, metagenomics, and transcriptomics. SPCSV is a quarantine virus with synergistic effects, which decimate yields. SPPV is the most prevalent DNA virus in sweet potato germplasm, with a tendency to persist in meristems, posing a significant risk for germplasm transfer between territories. Graft inoculation experiments revealed that while Tio Joe remained asymptomatic for 12 weeks and suppressed virus replication, Melinda displayed symptoms early on and exhibited high virus titers. Metagenomic analyses corroborated these observations and confirmed that SPCSV and SPPV were responsible. Transcriptomic analysis unveiled disparities in gene expression between Melinda and Tio Joe. Differential gene expression was heightened and altered in Melinda as the viruses disrupted its gene expression. Its defense strategies, such as inducing abscisic acid signaling, were insufficient to overcome disruptive viral effects like oxidative stress, rendering it susceptible. In contrast, Tio Joe had relatively stable differential gene expression, indicating resistance to SPPV–SPCSV coinfection. Overexpressed genes such as sirtuin, rapid alkalization factor, and nuclear pore anchor triggered quantitative resistance, supported with enriched organelles such as mitochondrion and pathways such as proteasome and cutin, suberine, and wax biosynthesis.

This study was conducted to characterize the genetic architecture underlying CLS response in table beet. A secondary objective was to test whether CLS-associated loci in table beet perform similarly across <i>B. vulgaris</i> crops. A diversity panel comprised of 168 table beet accessions and with an additional 70 accessions from all close relatives of table beet was screened for CLS response in replicated and inoculated field trials. Results from a genome-wide association study of additive effects revealed seven quantitative trait loci mapped to chromosomes 1, 3, 7, and 9 to explain 30% of the phenotypic variation for CLS response in table beet. When the performance of these loci was compared between a table beet background and a background of Swiss chard, sugar beet, and fodder beet, two loci exhibited significantly different responses. Among the <i>B. vulgaris</i> crops, these loci may be unique to table beet germplasm and could be useful for the improvement of CLS resistance in other crop types. For the improvement of CLS resistance in table beet, this study identified the cultivar Winter Keeper as a potentially valuable source of resistance.

An experiment was conducted at the University of Florida, West Florida Research and Education Center, Jay, FL, to evaluate the effect of turfgrass conversion to other landscape types on nutrient leaching and groundwater recharge. In April 2021, all surface vegetation was removed from existing turfgrass plots using a sod harvester. Thereafter, plots were planted or covered with three landscape types: a pollinator landscape with flowering forbs (<jats:italic>Mimosa sp</jats:italic>., <jats:italic>Coreopsis sp</jats:italic>., and <jats:italic>Phyla sp</jats:italic>.) + turfgrass (<jats:italic>Eremochloa ophiuroides</jats:italic>); a nitrogen (N)‐efficient lawn (<jats:italic>Arachis glabrata</jats:italic> + <jats:italic>Paspalum notatum</jats:italic>); and a low‐input landscape with unplanted woodchip mulch.

Lines derived from those crosses were screened at high doses of imidazolinones, which allowed identifying five lines with high levels of resistance.

Resistant lines exhibited cross resistance with halosulfuron (sulfonylurea). Resistance was confirmed under field conditions with doses 2X and 4X for imazethapyr and 4X–8X for halosulfuron of their respective label doses. While susceptible lines died, resistant lines exhibited no injury or growth reductions compared with nontreated controls. Sequencing of the <i>ALS</i> gene indicated that all resistant lines carried a Trp574Leu amino acid substitution, a mutation responsible for resistance in other species. Crosses between resistant lines and a susceptible line demonstrated that the inheritance of the mutation corresponded with the resistance phenotype in the F2. The resistance trait behaved as a single, fully dominant allele, which makes it easier to transfer it to carinata lines with desirable agronomic traits.
