摘要

bZIP 基因家族成员在植物生长发育、胁迫反应和光信号转导等多种生物过程中发挥着重要作用。尽管bZIP基因家族非常重要,但有关其在花生中功能的信息却很有限。在这项研究中,我们在花生基因组中共鉴定出 99 个 bZIP 基因家族成员,分布在 20 条染色体上。系统发生树分析将花生 bZIP 基因家族分为 10 组,其中 I、D、A 和 S 组分布最广。花生荚果的转录组分析表明,10 个 bZIP 家族基因对光有显著的诱导反应,表明它们可能参与了花生的光信号转导。在花生 bZIP 家族中,H 组包括六个基因:AhabZIP13、AhabZIP63、AhabZIP39、AhabZIP44、AhabZIP91 和 AhbZIP96。其中,AhbZIP63(AhHYH)基因在光诱导下的表达量显著增加,表明其在光信号转导中起着关键作用。对 AhbZIP63 (AhHYH) 的 DAP-seq 分析表明,它直接调控与紫外线响应和细胞对营养水平响应相关的基因。

Determination of the regulatory network of two bZIP transcription factors, AhHYH and AhHY5, in light signal regulation in peanut by DAP-seq

Members of bZIP gene family play crucial roles in various biological processes, including plant growth and development, stress response, and light signal transduction. Despite their significance, there is limited information on the function of the bZIP gene family in peanuts. In this investigation, we identified a total of 99 bZIP gene family members in the peanut genome, distributed across 20 chromosomes. Phylogenetic tree analysis categorized the peanut bZIP gene family into 10 groups, with groups I, D, A and S being the most widely distributed. Transcriptome analysis of peanut pods revealed that 10 bZIP family genes exhibited significant induction in response to light, suggesting their potential involvement in light signal transduction in peanuts. Within the peanut bZIP family, group H comprises six genes AhbZIP13, AhbZIP63, AhbZIP39, AhbZIP44, AhbZIP91 and AhbZIP96. Particularly, the expression of the AhbZIP63 (AhHYH) gene significantly increased under light induction, indicating a pivotal role in light signal transduction. DAP-seq analysis of AhbZIP63 (AhHYH) demonstrated its direct regulation of genes associated with UV response and cellular response to nutrient levels.
