Thioredoxin (Trx) genes are ubiquitous in plants and have many regulatory functions. These include seed germination, apoptosis, and cellular redox processes. In this study, 48 members of the Trx gene family were identified in grapevine (Vitis vinifera L.) through blasting in the 12 × Vitis genome according to Trx domain (PF00085). These are divided into five subfamilies (Trx-A, Trx-B, Trx-O, Trx-TPR and Trx-ERp29) based on their domain features. All are widely distributed in 16 of the 19 chromosomes and chromosomes Un. The gene nomenclature is based on the order of location on the chromosome. The analysis of cis-acting elements in promoters reveals that Trxs are involved in seed development and are responsive to various environmental stimuli. The qRT-PCR analysis of 16 Trx genes in ‘Pinot noir’ and ‘Thompson seedless’ during various stages of seed development show that VvTrxA16 and VvTrxB7 may participate in seed-specific regulation. In summary, our findings enable to provide a basis for the relationships between the VvTrx genes and seed development.

硫氧还蛋白 (Trx) 基因在植物中普遍存在并具有许多调节功能。这些包括种子萌发、细胞凋亡和细胞氧化还原过程。在本研究中，根据 Trx 结构域 (PF00085)，通过在 12 × Vitis基因组中进行爆破，在葡萄 ( Vitis vinifera L.) 中鉴定了Trx基因家族的48 个成员。根据它们的域特征，它们被分为五个子家族（Trx-A、Trx-B、Trx-O、Trx-TPR 和 Trx-ERp29）。全部广泛分布于19条染色体和Un染色体中的16条。基因命名法基于染色体上的位置顺序。启动子中顺式作用元件的分析表明，Trxs参与种子发育并对各种环境刺激作出反应。在种子发育的各个阶段对“黑比诺”和“汤普森无籽”中16 个Trx基因的 qRT-PCR 分析表明，VvTrxA16和VvTrxB7可能参与种子特异性调控。总之，我们的发现能够为VvTrx基因与种子发育之间的关系提供基础。
