Biotic and abiotic stresses have already seriously restricted the growth and development of , thereby influencing the quality and yield of its wood and turpentine. Recent studies have shown that C2H2 zinc finger protein transcription factors play an important role in biotic and abiotic stress response. However, the members and expression patterns of C2H2 TFs in response to stresses in have not been performed. In this paper, 57 C2H2 zinc finger proteins of were identified and divided into five subgroups according to a phylogenetic analysis. In addition, six Q-type containing the plant-specific motif 'QALGGH' were selected for further study under different stresses. The findings demonstrated that exhibit responsiveness towards various abiotic stresses, including drought, NaCl, ABA, PEG, HO, etc., as well as biotic stress caused by the pine wood nematode. In addition, and were nuclear localization proteins, and was a transcriptional activator. was selected as a potential transcriptional regulator in response to various stresses in . These findings laid a foundation for further study on the role of in stress tolerance.
生物和非生物胁迫已经严重限制了 的生长和发育,从而影响其木材和松节油的质量和产量。最近的研究表明,C2H2 锌指蛋白转录因子在生物和非生物胁迫反应中发挥着重要作用。然而,在 中,C2H2 TF 对胁迫的反应成员和表达模式尚未得到研究。在本文中,鉴定了 中的 57 个 C2H2 锌指蛋白,并根据系统发育分析将其分为五个亚组。此外,选择了六个含有植物特异性基序“QALGGH”的 Q 型 C2H2 蛋白进一步研究不同胁迫下的表达情况。研究结果表明, 对各种非生物胁迫(包括干旱、NaCl、ABA、PEG、HO 等)以及松材线虫引起的生物胁迫表现出响应性。此外, 是核定位蛋白, 是转录激活因子。 被选为响应 中各种胁迫的潜在转录调节剂。这些发现为进一步研究 在胁迫耐受中的作用奠定了基础。
