A better understanding of the extent convergent selection among crops could greatly improve breeding programs. We found that quantitative trait locus KRN2 in maize and its rice ortholog, OsKRN2, experienced selection. These orthologs encode WD40 proteins interact with a gene unknown function, DUF1644, to negatively regulate grain number both crops. Knockout or OsKRN2 increased yield by ~10% ~8%, respectively, no apparent trade-offs other agronomic traits. Furthermore, genome-wide scans...
Tocopherols are a class of four natural compounds that can provide nutrition and function as antioxidant in both plants animals. Maize kernels have low α-tocopherol content, the compound with highest vitamin E activity, thus, raising risk deficiency human populations relying on maize their primary source. In this study, two insertion/deletions (InDels) within gene encoding γ-tocopherol methyltransferase, Zea mays VTE4 (ZmVTE4), single nucleotide polymorphism (SNP) located ∼85 kb upstream...
Abstract α‐carotene is one of the important components pro‐vitamin A, which able to be converted into vitamin A in human body. One maize ( Zea mays L.) ortholog carotenoid hydroxylases Arabidopsis thaliana , ZmcrtRB3 was cloned and its role hydrolyzations addressed. mapped a quantitative trait locus (QTL) cluster for carotenoid‐related traits on chromosome 2 (bin 2.03) recombinant inbred line (RIL) population derived from By804 B73. Candidate‐gene association analysis identified 18...
Anther development from stamen primordium to pollen dispersal is complex and essential sexual reproduction. How this highly dynamic developmental process controlled genetically not well understood, especially for genes involved in specific key phases. Here we generated RNA sequencing libraries spanning 10 stages across the entirety of anther maize (Zea mays). Global transcriptome analyses revealed distinct phases cell division expansion, meiosis, maturation, mature pollen, which detected 50,...
Reproductive phasiRNAs (phased, small interfering RNAs), produced from numerous PHAS loci, are essential for plant anther development. transcripts enriched on endoplasmic reticulum-bound ribosomes in maize (Zea mays), but the impact of ribosome binding phasiRNA biogenesis remains elusive. Through profiling anthers at 10 developmental stages, we demonstrated that 24-PHAS bound by ribosomes, with patterns corresponding to timing and abundance transcripts. Ribosome is conserved among different...
SUMMARY Stalk lodging is a severe problem that limits maize production worldwide, although little attention has been given to its genetic basis. Here we measured rind penetrometer resistance (RPR), an effective index for stalk lodging, in multi‐parent population of 1948 recombinant inbred lines (RILs) and association 508 (AMP508). Linkage mapping identified 53 29 single quantitative trait loci (QTLs) 50 19 pairs epistatic interactions RPR the AMP508 population, respectively. Phenotypic...
