Drought is one of the major factors limiting global maize production. Exposure to long-term drought conditions inhibits growth and leads yield losses. Although several drought-responsive genes have been identified functionally analyzed, mechanisms underlying responses water recovery treatments not fully elucidated. To characterize how seedling respond stress at transcriptional level, we analyzed physiological differentially expressed (DEGs) in inbred line B73 under deficit conditions.The...
The early maize (Zea mays) seed undergoes several developmental stages after double fertilization to become fully differentiated within a short period of time, but the genetic control this highly dynamic and complex process remains largely unknown.

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...
The root system is fundamental for maize growth and yield. Characterizing its heterogeneity cell type-specific response to nitrate at the single-cell level will shed light on development nutrient uptake. We profiled transcriptomes of >7000 cells derived from tips seedlings grown media with or without nitrate, identified 11 major types tissues 85 nitrate-response genes, including several known metabolic genes. A pseudotime analysis showed a continuous series beginning meristematic zone that...
SUMMARY Sugarcane is the main source of sugar worldwide, and 80% sucrose production comes from sugarcane. However, genetic differentiation basis agronomic traits remain obscure. Here, we sequenced whole‐genome 219 elite worldwide sugarcane cultivar accessions. A total approximately 6 million high‐quality genome‐wide single nucleotide polymorphisms (SNPs) were detected. association study identified a 2198 SNPs that significantly associated with content, stalk number, plant height, diameter,...
Cadmium is a toxic, carcinogenic element that threatens food safety due to its tendency be absorbed by plants along with essential nutrients. This study conducted genome-wide association (GWAS) using SNP genotyping data from 170 natural maize populations analyze cadmium content in grains across three environments.

Abstract The MYB transcription factor genes play important roles in many developmental processes and various defense responses of plants. shikimate pathway is a major biosynthetic for the production three aromatic amino acids other compounds that are involved multiple plants, including protection against UV defense. Herein, we describe characterization R2R3‐MYB gene AtMYB15 as an activator Arabidopsis. protein nuclear localized transcriptional activation domain found its C‐terminal portion....
Abstract Carbon and nitrogen are the two main nutrients in maize (Zea mays L.) kernels, kernel filling metabolism determine seed formation germination. However, molecular mechanisms underlying relationship between corresponding carbon remain largely unknown. Here, we found that HEAT SHOCK PROTEIN 90.6 (HSP90.6) is involved both processes of nitrogen. A single-amino acid mutation within HATPase_c domain HSP90.6 led to small kernels. Transcriptome profiling showed expression amino...
The complex interactions between transcription factors (TFs) and their target genes in a spatially temporally specific manner are crucial to all cellular processes. Reconstruction of gene regulatory networks (GRNs) from expression profiles can help decipher TF-gene regulations variety contexts; however, the inevitable prediction errors GRNs hinder optimal data mining RNA-Seq transcriptome profiles. Here we perform an integrative study Zea mays (maize) seed development order identify key...

Abstract Background As maize originated in tropical or subtropical zones, most germplasm is extremely sensitive to low temperatures during the seedling stage. Clarifying molecular mechanism of cold acclimation would facilitate breeding tolerant varieties, which one major sustainability factors for crop production. To meet this goal, we investigated two inbred lines with contrasting levels tolerance at stage (IL85, a line; B73, line), and performed full-length transcriptome sequencing on root...
Pentatricopeptide repeat (PPR) proteins are a large protein family in higher plants and play important roles during seed development. Most reported PPR function mitochondria.
