Summary The husk leaf of maize ( Zea mays ) encases the ear as a modified and plays pivotal roles in protecting from pathogen infection, translocating nutrition for grains warranting grain yield. However, natural genetic basis variation width remains largely unexplored. Here, we performed genome‐wide association study identified 3‐bp InDel (insertion/deletion) coding region nitrate transporter gene ZmNRT2.5 . This polymorphism altered interaction strength with another transporter, ZmNPF5,...
Abstract DNA methylation affects agronomic traits and the environmental adaptability of crops, but natural polymorphisms in methylation–related genes their contributions to phenotypic variation maize (Zea mays) remain elusive. Here, we show that a polymorphic 10-bp insertion/deletion variant 3′UTR Zea methyltransferase2 (ZMET2) alters its transcript level accounts for number husk layers. ZMET2 encodes chromomethylase is required maintaining genome-wide CHG sequence context. Disruption...
DNA methylation plays vital roles in repressing transposable element activity and regulating gene expression. The chromatin-remodeling factor Decrease 1 (DDM1) is crucial for maintaining across diverse plant species, required RNA-directed (RdDM) to maintain mCHH islands maize (Zea mays). However, the mechanisms by which DDM1 involved RdDM are not well understood. In this work, we used chromatin immunoprecipitation coupled with high-throughput sequencing ascertain genome-wide occupancy of...
Summary Maize husk leaf – the outer leafy layers covering ear modulates kernel yield and quality. Despite its importance, however, genetic controls underlying development remain elusive. Our previous genome‐wide association study identified a single nucleotide polymorphism located in gene RHW1 ( Regulator of Husk Width ) that is significantly associated with leaf‐width diversity maize. Here, we further demonstrate polymorphic 18‐bp InDel (insertion/deletion) variant 3′ untranslated region...
Abstract Background The maize husk consists of numerous leafy layers and plays vital roles in protecting the ear from pathogen infection dehydration. Teosinte, wild ancestor maize, has about three small outer covering ear. Although several quantitative trait loci (QTL) underlying morphology variation have been reported, genetic basis traits between teosinte remains unclear. Results A linkage population including 191 BC 2 F 8 inbred lines generated line Mo17 X26–4 was used to identify QTL...
Abstract Background Root hair, a special type of tubular-shaped cell, outgrows from root epidermal cell and plays important roles in the acquisition nutrients water, as well interactions with biotic abiotic stress. Although many genes involved hair development have been identified, genetic basis natural variation growth has never explored. Results Here, we utilized maize association panel including 281 inbred lines tropical, subtropical, temperate origins to decipher phenotypic diversity...
Plants absorb sulfur from the environment and assimilate it into suitable forms for biosynthesis of a broad range molecules. Although biochemical pathway assimilation is known, how genetic differences contribute to natural variation in remains poorly understood. Here, using genome-wide association study, we uncovered single-nucleotide polymorphism (SNP) variant sulfite reductase (SiR) gene that was significantly associated with SiR protein abundance maize population. We also demonstrated...
