Significance Flowering time is a critical determinant of crop adaptation to local environments. As result natural and artificial selection, maize has evolved reduced photoperiod sensitivity adapt regions over 90° latitude in the Americas. Here we show that distant Harbinger-like transposon acts as cis -regulatory element repress ZmCCT9 expression promote flowering under long days higher latitudes. The at another functional second flowering-time gene, ZmCCT10 , arose sequentially following...
Summary Flowering time is a major determinant of the local adaptation plants. Although numerous loci affecting flowering have been mapped in maize, their underlying molecular mechanisms and roles remain largely unknown. Here, we report identification characterization MADS ‐box transcription factor Zm 69 that functions as activator through ZmRap2.7‐ ZCN 8 regulatory module contributes to adaptation. We show underlies quantitative trait locus controlling difference between maize its wild...
Maize (Zea mays) tassels underwent profound morphological changes during maize domestication and improvement. Although a number of genes affecting inflorescence development have been identified, the genetic basis in since is not well understood. Here, using large population 866 maize-teosinte BC2 S3 recombinant inbred lines genotyped 19 838 single nucleotide polymorphism (SNP) markers, we performed high-resolution quantitative trait locus (QTL) mapping for five tassel traits. We showed that...
Gene expression regulation plays an important role in controlling plant phenotypes and adaptation. Here, we report a comprehensive assessment of gene variation through the transcriptome analyses large maize-teosinte experimental population. Genome-wide mapping identified 25 660 quantitative trait loci (eQTL) for 17 311 genes, capturing unprecedented range variation. We found that local eQTL were more frequently mapped to adjacent displaying mode piggybacking, which consequently created...
Summary The number of leaves and their distributions on plants are critical factors determining plant architecture in maize ( Zea mays ), leaf is frequently used as a measure flowering time, trait that key to local environmental adaptation. Here, using large set 866 maize‐teosinte BC 2 S 3 recombinant inbred lines genotyped by 19 838 single nucleotide polymorphism markers, we conducted comprehensive genetic dissection assess the its relationship time. We demonstrated two components total...
Alternative splicing (AS) enhances transcriptome diversity and plays important roles in regulating plant processes. Although widespread natural variation AS has been observed plants, how is regulated contribute to phenotypic poorly understood. Here, we report a population-level assembly genome-wide association study identify quantitative trait loci (sQTLs) developing maize (Zea mays) kernels from 368 inbred lines. We detected 19,554 unique sQTLs for 6570 genes. Most showed small isoform...
Abstract The macronutrient phosphorus is essential for plant growth and development. Plants have evolved multiple strategies to increase the efficiency of phosphate (Pi) acquisition protect themselves from Pi starvation. However, crosstalk between homeostasis development remains be explored. Here, we report that overexpressing microRNA399 (miR399) in maize (Zea mays) associated with premature senescence after pollination. Knockout ZmPHO2 (Phosphate 2), a miR399 target, resulted similar...
A 178-bp copy number variation in the ZmMADS1 promoter represses expression and results delayed flowering, which has been a target of selection during maize spread into higher altitudes. promotes flowering via autonomous pathway by directly activating ZmMADS69 ZCN8, while repressing ZmRap2.7.
Flowering time is a key trait determining the local adaptation of plants. CONSTANS (CO) core regulator controlling photoperiodic flowering in Arabidopsis (Shim et al., 2017). Heading date 1 (Hd1), CO ortholog rice, promotes heading under short-day (SD) conditions but inhibits long-day (LD) (Yano 2000). Miller al. (2008) identified constans Zea mays1 (conz1), maize homologue, that exhibited distinct diurnal expression patterns varied photoperiods. However, how conz1 contributes to variation...
Seed germination is an important agronomic trait that affects crop yield and quality. Rapid uniform seed traits are required in agricultural production. Although several genes involved have been identified Arabidopsis rice, the genetic basis governing maize remains unknown. Herein, we conducted a genome-wide association study to determine architecture of two traits, speed, consistency, diverse panel. We genotyped 321 inbred populations with tropical, subtropical, or temperate origins using...
Abstract The macronutrient phosphorus is essential for plant growth and development. Plants have evolved multiple strategies to increase the efficiency of Pi acquisition protect themselves from starvation. However, crosstalk between homeostasis development remains be explored. Here, we report that overexpressing microRNA399 in maize induced a premature aging syndrome after pollination. Knockout ZmPHO2 , one miR399 targets, resulted similar phenotype. Strikingly, found INDETERMINATE1 (ID1),...
