which was rich in bioactive compounds such as polysaccharides, alkaloids, amino acids, and flavonoids, had significant medicinal value and ability to resist stresses. Studies had demonstrated that genes were one of the crucial regulators in controlling plant development and growth and stress response. Genome-wide identification and characterization of the 18 genes were displayed. According to phylogenetic relationships, the family genes were divided into 4 groups and the conserved motifs of - within the same group were similar. All genes were localized in the nucleus and randomly mapped on 10 chromosomes. The GATA genes in experienced one pair of tandem duplication and 4 pairs of segment duplications to expand the family genes. Additionally, we found that the 2000 bp upstream promoter region of the genes harbored 23 types of -acting elements that were categorized into plant growth and development, phytohormone responsiveness, and stress responsiveness. - were diversely expressed across different tissues (root, leaf, stem, flower), exposed to salt stress, and following MeJA treatment. Co-expression analysis between and enzyme-encoding genes involved in the biosynthesis of flavone showed that (LOC110104562) and (LOC110098370) may be potential downstream targets of to regulate flavonoid biosynthesis to adapt to salt stress. Furthermore, we confirmed that may act as a key member to resist stress. The collective findings of this study shed light on the function of genes and molecular breeding of .
其富含多糖、生物碱、氨基酸和黄酮类等生物活性化合物,具有显著的药用价值和抗逆能力。研究表明,基因是控制植物发育、生长和应激反应的关键调节因子之一。展示了18个基因的全基因组鉴定和特征分析。根据系统发育关系,该家族基因分为4组,同一组内的保守基序相似。所有基因都定位于细胞核,并随机分布在10条染色体上。该植物中的GATA基因经历了一对串联重复和4对片段重复以扩展家族基因。此外,我们发现这些基因的2000 bp上游启动子区域含有23种类型的顺式作用元件,这些元件可分为植物生长发育、植物激素响应和应激响应。它们在不同组织(根、叶、茎、花)中、暴露于盐胁迫下以及茉莉酸甲酯处理后表现出不同的表达。与黄酮生物合成中涉及的酶编码基因的共表达分析表明,(LOC110104562)和(LOC110098370)可能是调控黄酮类生物合成以适应盐胁迫的潜在下游靶点。此外,我们证实其可能作为抗逆的关键成员。本研究的总体发现揭示了该基因的功能以及该植物的分子育种。
