野生番茄物种具有显着的非生物胁迫耐受性。至少在茄属植物中,这可能是对其自然相对恶劣的栖息地的一种适应。有趣的是,转座因子的插入似乎与白英的抗逆性呈正相关。也有证据表明,不仅在西红柿中存在代谢核心应激反应,这可能会导致应激反应的改善。在该项目中,将首先研究“番茄遗传资源中心”收集的近50个不同的茄属pennellii品系,以改善盐和干旱胁迫反应,并将产生这些品系的泛(epi)基因组。然后将使用系统生物学方法详细分析选定的品系,以发现胁迫反应的分子关系,特别是转座子的作用。在一种互补的方法中,选择了含有一小部分S。pennellii基因组将用于发现介导应激反应的基因/转座子。最后,将使用鉴定的基因进行第一验证实验。
英文摘要
Wild tomato species are characterized by a remarkable abiotic stress tolerance. At least in Solanum pennellii this is likely an adaptation to its natural relatively harsh habitat. Interestingly, there seems to be a positive correlation between the stress tolerance of Solanum pennellii and the insertion of transposable elements. There is also evidence for a metabolic core stress response not only in tomatoes, which may lead to an improved stress response. In this project, almost 50 different Solanum pennellii lines in the collection of the "Tomato Genetic Resource Center" will first be investigated for an improved salt and drought stress response and a pan(epi)genome of these lines will be generated. Selected lines will then be analyzed in detail using a systems biology approach to find the molecular relationship of the stress response and especially the role of the transposons. In a complementary approach, selected cultivated tomato lines harboring a small part of the S. pennellii genome will be used to find genes/transposons that mediate stress response. Finally, first validation experiments with the identified genes will be performed.
