AI Technical Summary
Technical Problem
In existing technologies, tomato growth is restricted under drought stress, leading to reduced yields, and there is a lack of effective means of regulating drought-resistant genes.
Method used
By overexpressing the SlTCP17 gene or its encoded protein, the expression level and activity of SlTCP17 protein in tomatoes were increased, and transgenic plants were constructed to enhance their resistance to drought stress.
Benefits of technology
It improved the growth and biomass accumulation of tomatoes under drought conditions, reduced leaf wilting and root inhibition, lowered the relative electrical conductivity of leaves and the accumulation of reactive oxygen species, enhanced photosynthetic capacity, and significantly improved drought resistance.

Abstract
本发明属于植物基因工程技术，具体涉及SlTCP17基因或其编码蛋白在调控番茄干旱胁迫抗性中的应用。番茄SlTCP17基因的核苷酸序列如SEQ ID NO:1所示，其编码蛋白的氨基酸序列如SEQ ID NO:2所示。通过调控SlTCP17基因和 / 或蛋白的表达水平，提高番茄干旱胁迫抗性或培育番茄新品种。实验证明，过表达植株经干旱胁迫处理，其地上部生长和根系生长更接近正常水平、叶片的保水抗旱能力高、生物量积累多、茎粗下降少、植物根系受到的抑制少、叶片的相对电导率和叶绿素荧光能力更接近正常水平，且可减少植株体内过量ROS的积累。本发明首次验证了番茄SlTCP17基因或其编码蛋白在番茄品种选育中的应用，对于耐干旱番茄品种选育具有重要作用。
