Auxin is a plant hormone that plays key roles in both shoot gravitropism and inflorescence development. However, these two processes appear to be parallel regulated by distinct players. Here, we report the maize (Zea mays) prostrate stem1 mutant, which allelic classic mutant lazy plant1 (la1), displays growth with reduced defective Map-based cloning identified ZmLA1 as functional ortholog of LAZY1 rice (Oryza sativa) Arabidopsis (Arabidopsis thaliana). It has unique role development enriched...
Anther cuticle and pollen exine are protective barriers for development fertilization. Despite that several regulators have been identified anther in rice (Oryza sativa) Arabidopsis (Arabidopsis thaliana), few genes characterized maize (Zea mays) the underlying regulatory mechanism remains elusive. Here, we report a novel male-sterile mutant maize, irregular exine1 (ipe1), which exhibited glossy outer surface, abnormal Ubisch bodies, defective exine. Using map-based cloning, IPE1 gene was...
SUMMARY Metabolites are the intermediate and final products of metabolism, which play essential roles in plant growth, evolution adaptation to changing climates. However, it is unclear how contributes metabolic variation plants. Here, we investigated metabolomics data from leaf seed tissues maize rice. Using principal components analysis based on metabolites but not metabolites, could be clearly separated for rice Indica Japonica accessions, while two subgroups, temperate tropical, showed...
Modification of unsaturated fatty acid (FA) levels has been found to accompany multiple abiotic stress acclimations in many plants. Delta 12 desaturase (FAD2) plays a critical role the synthesis polyunsaturated FAs plant cells by converting oleic (18:1) linoleic (18:2). To better understand relationship between metabolism and adaptation, expression FAD2 gene changes FA compositions under various stresses phytohormone treatments Arabidopsis thaliana was investigated this study. A 1 423-bp...
Cold limits the growth and yield of maize in temperate regions, but molecular mechanism cold adaptation remains largely unexplored maize. To identify early events during shock, seedlings were treated under 4 °C for 30 min 2 h, analyzed at both proteome phosphoproteome levels. Over 8500 proteins 19,300 phosphopeptides quantified. About 660 620 responsive protein abundance or site-specific phosphorylation levels, only 65 shared between them. Functional enrichment analysis cold-responsive...
The anther cuticle, which is primarily composed of lipid polymers, crucial for pollen development and plays important roles in sexual reproduction higher plants. However, the mechanism underlying biosynthesis polymers maize (Zea mays. L.) remains unclear. Here, we report that male-sterile mutant shrinking 1 (sa1), allelic to classic male sterile 33 (ms33), displays defective cuticle premature microspore degradation. We isolated MS33 via map-based cloning. encodes a putative...
Maize has become one of the most widely grown grains in world, and stay-green mutant allows these plants to maintain their green leaves photosynthetic potential for longer following anthesis than non-mutated plants. As a result, have higher production rate non-stay-green varieties due prolonged grain-filling period. In this study, candidate genes related visual at maturation stage maize were investigated. The F2 population was derived from T01 (stay-green) Xin3 (non-stay-green) cross. Two...
Seed size is an important factor contributing to maize yield, but its molecular mechanism remains unclear. The seed coat, which serves as one of the three components grain, determines a certain extent. coat also shares maternal genotype and ideal material for studying heterosis.In this study, self-pollinated seeds hybrid Yudan888 parental lines were continuously collected from 0 day after pollination (DAP) 15 DAP phenotyping, cytological observation RNA-seq. phenotypic data showed that 3 8...
Temperature is a major factor regulating plant growth. To reproduce at extreme temperatures, plants must develop normal reproductive organs when exposed to temperature changes. However, little known about the underlying molecular mechanisms. Here, we identified maize (Zea mays) mutant thermosensitive vanishing tassel1-R (tvt1-R), which lacks tassels high (restrictive) temperatures due shoot apical meristem (SAM) arrest, but forms moderate (permissive) temperatures. The critical stage for...
The contamination of agricultural soil with cadmium (Cd), a heavy metal, poses significant environmental challenge, affecting crop growth, development, and human health. Previous studies have established the pivotal role ZmHMA3 gene, P-type ATPase metal transporter, in determining variable Cd accumulation maize grains among 513 inbred lines. To decipher molecular mechanism underlying mutation-induced phenotypic differences mediated by ZmHMA3, we conducted quantitative tandem mass tag...
Abstract Important traits related to maize ( Zea mays L.) grain yield, such as kernel row number, ear length, number per row, are determined during the development of female inflorescence. There is a significant positive correlation between yield component and activity inflorescence meristem (IM). To find key stage heterosis in ear, immature ears (from IM until end floral [FM] stage) Yudan888 its parent lines were sampled assay phenotype for comparative transcriptomics analysis. The length...
Soil contamination by heavy metals has become a prevalent topic due to their widespread release from industry, agriculture, and other human activities. Great progress been made in elucidating the uptake translocation of cadmium (Cd) accumulation rice. However, there is still little known about corresponding maize. In current study, we performed comparative RNA-Seq-based approach identify differentially expressed genes (DEGs) maize immature kernel related Cd stress. total, 55, 92, 22, 542...
Phenolamides are important secondary metabolites in plant species. They play roles defense responses against pathogens and insect herbivores, protection UV irradiation floral induction development. However, the accumulation variation phenolamides content diverse maize lines genes responsible for their biosynthesis remain largely unknown. Here, we combined genetic mapping, protein regulatory network bioinformatics analysis to further enhance understanding of biosynthesis. Sixteen were...
Maize is one of the main food crops in world, and cultivating high-yield high-quality maize varieties great significance addressing security issues. Leaves are crucial photosynthetic organs maize, leaf senescence can result degradation chlorophyll. This, turn, impacts activity accumulation products. Delaying increasing carbon assimilation enhance grain yield biomass production. The stay green an important trait closely related to yield, feed quality resistance. Therefore, this study employed...
Abstract Suwan germplasm plays important roles in maize breeding tropical/subtropical regions, especially southern China. To analyze the genetic characteristics of germplasm, one panel 73 lines derived from population and temperate resources were collected genotyped using 56,110 single‐nucleotide polymorphism (SNP) markers. The results revealed four subgroups, namely, QR273, Ki32, HCL645, PH4CV, with an average distance 0.304, varying 0.001 to 0.370. In addition, many identical‐by‐descent...
