C2H2锌指蛋白（C2H2-ZFP）是植物生长发育的重要调控蛋白，对干旱、低温和盐胁迫具有广泛的响应性，并影响植物体内黄酮类化合物的后期积累。茶是世界上最受欢迎的饮料，其质量在很大程度上取决于茶树的生理状态和生长环境。目前，对茶树C2H2-ZFP基因家族的了解还不多。O. Kuntze还没有出现。在本研究中，134 CsC2H2-ZFP基因的鉴定和随机分布在15条染色体上。CsC2H2-ZFP基因家族可分为4个分支，同一分支内CsC2H2-ZFP基因结构和基序组成相似。片段重复和负选择是CsC2H2-ZFP基因家族扩展的主要驱动力。表达模式表明CsC2H2-ZFPs响应于不同的胁迫，包括干旱，盐，冷和茉莉酸甲酯（MeJA）处理。特别是，一些C2H2-ZFPs表现出显着的儿茶素含量的相关性，并响应于MeJA处理，这可能有助于茶叶品质和特殊的涩味。本研究为进一步研究C2H2型锌指蛋白在柑橘逆境响应和品质相关代谢物积累中的作用奠定了基础。sinensis。
The C2H2-zinc finger protein (C2H2-ZFP) is essential for the regulation of plant development and widely responsive to diverse stresses including drought, cold and salt stress, further affecting the late flavonoid accumulation in higher plants. Tea is known as a popular beverage worldwide and its quality is greatly dependent on the physiological status and growing environment of the tea plant. To date, the understanding of C2H2-ZFP gene family in Camellia sinensis [L.] O. Kuntze is not yet available. In the present study, 134 CsC2H2-ZFP genes were identified and randomly distributed on 15 chromosomes. The CsC2H2-ZFP gene family was classified into four clades and gene structures and motif compositions of CsC2H2-ZFPs were similar within the same clade. Segmental duplication and negative selection were the main forces driving the expansion of the CsC2H2-ZFP gene family. Expression patterns suggested that CsC2H2-ZFPs were responsive to different stresses including drought, salt, cold and methyl jasmonate (MeJA) treatment. Specially, several C2H2-ZFPs showed a significant correlation with the catechins content and responded to the MeJA treatment, which might contribute to the tea quality and specialized astringent taste. This study will lay the foundations for further research of C2H2-type zinc finger proteins on the stress responses and quality-related metabolites accumulation in C. sinensis.
