Drought represents a major constraint on maize production worldwide. Understanding the genetic basis for natural variation in drought tolerance of may facilitate efforts to improve this trait cultivated germplasm. Here, using genome-wide association study, we show that miniature inverted-repeat transposable element (MITE) inserted promoter NAC gene (ZmNAC111) is significantly associated with tolerance. The 82-bp MITE represses ZmNAC111 expression via RNA-directed DNA methylation and H3K9...
Abstract Drought is a major environmental factor limiting wheat production worldwide. However, the genetic components underlying drought tolerance are largely unknown. Here, we identify DREB transcription gene (TaDTG6-B) by genome-wide association study that tightly associated with in wheat. Candidate analysis revealed 26-bp deletion TaDTG6-B coding region induces gain-of-function for TaDTG6-BDel574, which exhibits stronger transcriptional activation, protein interactions, and binding...
Summary Drought stress limits wheat production and threatens food security world‐wide. While ethylene‐responsive factors (ERFs) are known to regulate plant response drought stress, the regulatory mechanisms responsible for a tolerant phenotype remain unclear. Here, we describe positive role of TaERF87 in mediating tolerance stress. overexpression (OE) enhances tolerance, while silencing leads sensitivity wheat. RNA sequencing with biochemical assays revealed that activates expression proline...
Drought is a major abiotic stress that threatens maize production globally. A previous genome-wide association study identified significant between the natural variation of ZmTIP1 and drought tolerance seedlings. Here, we report on comprehensive genetic functional analysis, indicating ZmTIP1, which encodes S-acyltransferase, plays positive role in regulating length root hairs level maize. We show enhancing expression transgenic Arabidopsis increased hair length, as well plant to water...
Wheat is a staple crop produced in arid and semi-arid areas worldwide, its production frequently compromised by water scarcity. Thus, increased drought tolerance priority objective for wheat breeding programmes, among their targets, the NAC transcription factors have been demonstrated to contribute plant response. However, natural sequence variations these genes largely unexplored potential roles tolerance. Here, we conducted candidate gene association analysis of stress-responsive subfamily...
The role of abscisic acid (ABA) receptors, PYR1/PYL/RCAR (PYLs), is well established in ABA signalling and plant drought response, but limited research has explored the regulation wheat PYLs this process, especially effects their allelic variations on tolerance or grain yield. Here, we found that overexpression a TaABFs-regulated PYL gene, TaPYL1-1B, exhibited higher sensitivity, photosynthetic capacity water-use efficiency (WUE), all contributed to than wild-type plants. This heightened...
SQUAMOSA promoter binding protein-like (SPL) transcription factors (TFs) are plant-specific and play vital regulatory roles in plant growth development. Even though they one of the unique groups TFs plants, their characteristics, evolutionary relationships expression patterns largely unknown maize, an important food crop worldwide. In this study, we identified 31 SPL genes (ZmSPLs) maize B73 genome. A phylogenetic analysis showed that these were divided into six (Groups 1–6) members within...
Trehalose-6-phosphate phosphatases genes (TPPs) are involved in the development and stress response of plants by regulating biosynthesis trehalose, though little is currently known about TPPs common wheat (Triticum aestivum L.).In this study, we performed a genome-wide identification TPP gene family wheat, identified total 31 TaTPP genes. These were subdivided into six subfamilies based on phylogenetic relationships conservation protein monocot eudicot plants. The majority represented 2-3...
Drought stress limits crop yield, but the molecular modulators and their mechanisms underlying trade-off between drought resistance growth development remain elusive. Here, a grain width weight2 (GW2)-like really interesting new gene finger E3 ligase, TaGW2, was identified as pivotal regulator of both kernel responses in wheat (Triticum aestivum). TaGW2 overexpression enhances leads to yield drag under full irrigation conditions. In contrast, knockdown or knockout attenuates remarkably...
Summary Plant architecture is a key determinant of crop productivity and adaptation. The highly conserved microRNA319 (miR319) family functions in various biological processes, but little known about how miR319 regulates plant wheat ( Triticum aestivum ). Here, we determined that the miR319/TaGAMYB3 module controls grain yield common wheat. Repressing tae‐miR319 using short tandem target mimics resulted favorable traits, including increased height, reduced tiller number, enlarged spikes flag...
Plants activate a variable response to drought stress by modulating transcription of key genes. However, our knowledge genetic variations governing gene expression in remains limited natural germplasm. Here, we performed comprehensive analysis the transcriptional variability 200 wheat accessions using systems genetics approach integrating pan-transcriptome, co-expression networks, transcriptome-wide association study (TWAS), and quantitative trait loci (eQTLs) mapping. We identified 1621...
Abstract Soil salinity can adversely affect crop growth and yield, an improved understanding of the genetic factors that confer salt tolerance could inform breeding strategies to engineer salt‐tolerant crops improve productivity. Here, a group K + ‐preferring HKT transporters, TaHKT8 , TaHKT9 TaHKT10 were identified negatively regulate wheat shoot accumulation tolerance. A genome‐wide association study (GWAS) candidate gene analysis further revealed TaHKT9‐B substantially underlies natural...
Many studies in Arabidopsis and rice have demonstrated that HD-Zip transcription factors play important roles plant development responses to abiotic stresses. Although common wheat (Triticum aestivum L.) is one of the most widely cultivated consumed food crops world, function proteins still largely unknown. To explore potential biological functions genes wheat, we performed a bioinformatics gene expression analysis family. We identified 113 members from classified them into four subfamilies...
Abstract Background Previous studies have shown that ABFs (abscisic acid-responsive transcription factors) are important ABA-signaling components participate in abiotic stress response. However, little is known about the function of Triticum aestivum . In addition, although various been identified other species, phylogenetic relationship between ABF factors has not systemically investigated land plants. Results this study, we collected from plants and analyzed these genes. The genes present...
Wheat grain development is a robust biological process that largely determines quality and yield. In this study, we investigated the transcriptome of winter wheat cv. Xiaoyan-6 at four developmental stages (5, 10, 15, 20 days post-anthesis), using high-throughput RNA sequencing (RNA-Seq). We identified 427 grain-specific transcription factors (TFs) 1653 differentially expressed TFs during as well co-expression regulation network (GrainNet) their predicted co-expressed genes. Our study ten...
The stomatal index of the leaf is ratio number stomata to total and epidermal cells. Comparing with density, relatively constant in environmental conditions age and, therefore, diagnostic characteristics for a given genotype or species. Traditional assessment methods involve manual counting cells microphotographs, which labor-intensive time-consuming. Although several automatic measurement algorithms density have been proposed, no pipelines are currently available. main aim this research...
Because allohexaploid wheat genome contains ABD subgenomes, how the expression of homoeologous genes is coordinated remains largely unknown, particularly at co-transcriptional level. Alternative polyadenylation (APA) an important part regulation, which crucial in developmental processes and stress responses. Drought a major threat to stable yield wheat. Focusing on APA, we used poly(A) tag sequencing track site dynamics under drought stress. The results showed that led extensive APA...
Abstract Stomata are important channels for the control of gas exchange between plants and atmosphere. To examine genetic architecture wheat stomatal index, we performed a genome‐wide association study (GWAS) using panel 539 accessions 450 678 polymorphic single nucleotide polymorphisms (SNPs) that were detected wheat‐specific 660K SNP array. A total 130 SNPs to be significantly associated with index in both leaf surfaces seedlings. These significant distributed across 16 chromosomes...
