摘要:

JRL(jacalin-related lectin)蛋白是植物凝集素家族成员之一,具有特异糖结合活性,在植物胁迫响应等过程中发挥重要作用。为解析玉米JRLZmJRL)基因家族功能,利用生物信息学方法对ZmJRL基因进行鉴定与分析,并利用MaizeGDB网站公布的转录组数据检测ZmJRL基因在不同组织和不同胁迫处理下的差异表达情况。结果显示,玉米中共有16个ZmJRL基因,命名为ZmJRL01~ZmJRL16,不均匀分布在玉米7条染色体上,它们的蛋白结构相似,均具有jacalin结构域,多数为碱性稳定蛋白。亚细胞定位结果显示,ZmJRL蛋白主要定位于细胞质、细胞核、叶绿体等部位。系统进化分析将玉米JRL蛋白分为3个类群,与水稻亲缘关系较近,相同类群的ZmJRL蛋白具有相似的保守基序。ZmJRL基因启动子区具有多种非生物胁迫和激素胁迫响应元件。转录组数据分析表明,ZmJRL基因表达具有组织特异性,多数ZmJRL基因能对冷、热、盐、干旱等至少1种逆境胁迫响应表达。以上研究结果为进一步探究ZmJRL基因的生物学功能提供了基础。

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 JRLZmJRL) 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.
