Abstract The adverse effects of mounting environmental challenges, including extreme temperatures, threaten the global food supply due to their impact on plant growth and productivity. Temperature extremes disrupt genetics, leading significant issues eventually damaging phenotypes. Plants have developed complex signaling networks respond tolerate temperature stimuli, genetic, physiological, biochemical, molecular adaptations. In recent decades, omics tools other strategies rapidly advanced,...

In this context, from total 163,782 derived resequencing RNA-sequencing 41 accessions wild diploid ancestors,...
Focus has centered on C-partitioning in stems of sugarcane (Saccharum sp.) due to their high-sucrose accumulation features, relevance other grasses, and rising economic value. Here we review how balances between sucrose storage, respiration, cell wall biosynthesis. The specific topics involve 1) exceptionally high levels (up over 500 mM), 2) a potential, turgor-sensitive system for partitioning storage inside (cytosol vacuole) outside cells, 3) mechanisms prevent back-flow extracellular...
Peanut (Arachis hypogaea; 2n = 4x 40) is a nutritious food and good source of vitamins, minerals, healthy fats. Expansion genetic genomic resources for enhancement cultivated peanut has gained momentum from the sequenced genomes diploid ancestors peanut. To facilitate high-throughput genotyping Arachis species, 20 genotypes were re-sequenced genome-wide single nucleotide polymorphisms (SNPs) selected to develop large-scale SNP array. For flexibility in applications, SNPs polymorphic between...
Abstract Contamination of crops with aflatoxin is a serious global threat to food safety. Aflatoxin production by Aspergillus flavus exacerbated drought stress in the field and oxidative vitro. We examined transcriptomes three toxigenic atoxigenic isolates A. conducive non-conducive media varying levels H 2 O investigate relationship secondary metabolite production, carbon source, stress. found that employ distinct mechanisms remediate damage, source affected isolates’ expression profiles....
The infection of maize and peanut with Aspergillus flavus subsequent contamination aflatoxin pose a threat to global food safety human health, is exacerbated by drought stress. Drought stress-responding compounds such as reactive oxygen species (ROS) are associated fungal stress responsive signaling secondary metabolite production, can stimulate the production A. in vitro. These metabolites have been shown possess diverse functions soil-borne fungi including antibiosis, competitive...
The colonization of maize (Zea mays L.) and peanut (Arachis hypogaea by the fungal pathogen Aspergillus flavus results in contamination kernels with carcinogenic mycotoxins known as aflatoxins leading to economic losses potential health threats humans. regulation aflatoxin biosynthesis various spp. has been extensively studied, shown be related oxidative stress responses. Given that environmental stresses such drought heat result accumulation reactive oxygen species (ROS) within host plant...
Sugarcane (Saccharum spp.) and other members of Saccharum spp. are attractive biofuel feedstocks. One the two World Collections Related Grasses (WCSRG) is in Miami, FL. This WCSRG has 1002 accessions, presumably with valuable alleles for biomass, important agronomic traits, stress resistance. However, not been fully exploited by breeders due to its lack characterization unmanageable population. In order optimize use this genetic resource, we aim 1) genotypically evaluate all accessions...
