Stalk lodging in maize results substantial yield losses worldwide. These could be prevented through genetic improvement. However, breeding efforts and genetics studies are hindered by lack of a robust economical phenotyping method for assessing stalk resistance. A field-based platform that induces failure patterns consistent with natural events measures bending strength field-grown plants was recently developed. Here we examine the association between data gathered from this new counts...
Premature senescence in annual crops reduces yield, while delayed senescence, termed stay-green, imposes positive and negative impacts on yield nutrition quality. Despite its importance, scant information is available the genetic architecture of maize (Zea mays) other cereals. We combined a systematic characterization natural diversity for coexpression networks derived from transcriptome analysis normally senescing stay-green lines. Sixty-four candidate genes were identified by genome-wide...
Fusarium head blight (FHB) is one of the most economically destructive diseases wheat (Triticum aestivum L.), causing substantial yield and quality loss worldwide. graminearum predominant causal pathogen FHB in U.S., produces deoxynivalenol (DON), a mycotoxin that accumulates grain throughout infection. results kernel damage, visual symptom quantified by human observer enumerating or estimating percentage Fusarium-damaged kernels (FDK) sample grain. To date, FDK estimation efficient accurate...
Abstract Source and sink interactions play a critical but mechanistically poorly understood role in the regulation of senescence. To disentangle genetic molecular mechanisms underlying source–sink-regulated senescence (SSRS), we performed phenotypic, transcriptomic, systems genetics analysis induced by lack strong maize (Zea mays). Comparative genotypes with contrasting SSRS phenotypes revealed that feedback inhibition photosynthesis, surge reactive oxygen species, resulting endoplasmic...
Hybrid breeding in sorghum [Sorghum bicolor (L.) Moench] utilizes the cytoplasmic-nuclear male sterility (CMS) system for seed production and subsequently harnesses heterosis. Since cost of developing evaluating inbred hybrid lines CMS is costly time-consuming, genomic prediction parental hybrids based on genetic data genotype. We generated 602 by crossing two female (A) with 301 diverse elite (R) from association panel collected phenotypic agronomic traits over years. genotyped parents...
Abstract Fusarium head blight (FHB) remains one of the most destructive diseases in wheat. Primarily caused by mycotoxigenic fungi graminearum , FHB results both widespread yield loss and deoxynivalenol (DON) contamination wheat grain. Phenotyping for Fusarium‐ damaged kernels (FDKs) is efficient estimate resistance to DON accumulation outside performing costly time‐consuming laboratory assays. However, manual phenotyping FDKs can be tedious highly subjective observers. This study developed...
Sorghum grain mold (SGM) is an important multifungal disease complex affecting sorghum (Sorghum bicolor) production systems worldwide. SGM-affected can be contaminated with potent fumonisin mycotoxins produced by Fusarium verticillioides, a prevalent SGM-associated taxon. Historically, efforts to improve resistance SGM have achieved only limited success. Classical approaches evaluating are based solely on severity, which offers little insight regarding the distinct symptom manifestations...

Abstract Sorghum [ bicolor (L.) Moench] is a potential crop for organic production that could help meet the demand increase in food products and feed grains, but no efforts have been made to improve sorghum breeding tools, techniques, methods this cropping system. Based on revelations other crops, focal traits their prioritization optimize use likely differs from conventional targets. This study evaluated yield performance, agronomic characteristics, biotic stress resistance under certified...
