玉米JRL基因家族全基因组鉴定及表达分析
Genome-wide Identification and Expression Analysis of Maize JRL Gene Family
摘要
Abstract
Jacalin-related lectin(JRL)proteins belong to the plant lectin family,exhibit specific sugar-binding activity and play crucial roles in processes such as plant stress response.To understand the function of the maize JRL(ZmJRL)gene family,the bioinformatics methods were used to identify and analyze the ZmJRL genes.Additionally,the transcriptomic data from the MaizeGDB website were utilized to investigate the specific expression of ZmJRL genes in various tissues and under different stress conditions.The results revealed that a total of 16 ZmJRL genes in maize were identified,designated as ZmJRL01 to ZmJRL16.They were unevenly distributed on 7 chromosomes of maize.These proteins exhibited structural similarity,possessing jacalin domains and mostly being alkaline-stable proteins.Subcellular localization analysis indicated that ZmJRL proteins primarily localized in the cytoplasm,nucleus and chloroplasts.Phylogenetic analysis divided maize JRL proteins into 3 clades,which were closely related to rice(Oryza sativa L.).The ZmJRL proteins with same clades had similar motifs.The promoter of ZmJRL genes contained various cis-elements that respond to abiotic stress and hormones.Transcriptome analysis showed that the ZmJRL genes had tissue expression specificity,and the majority of ZmJRL genes could respond to at least one type of adversity stress,such as cold,heat,salt and drought.Above results provided a reference for further study on the biological functions of ZmJRL genes.关键词
