Description
Technical Field
The invention relates to the technical field of gene editing, in particular to application of tomato WRKY37 protein in regulation and control of tomato leaf senescence resistance and improvement of tomato yield.
Background
Aging is a ubiquitous, important physiological phenomenon, generally referred to as the process by which the organs of an organism or the physiological functions of the whole individual gradually decline and eventually die. Leaves are important places where plants synthesize organic compounds using light energy, and are also one of the most sensitive organs of plants to senescence (Woo et al, 2019). With the increasing knowledge of the genetic control of senescence in the field, transcription factors of the WRKY, MYB and NAM/ATAF1/CUC2(NAC) families become regulating factors of the process (Kim et al, 2018), and researches on regulating leaf senescence by the transcription factors of the WRKY family are frequently reported in recent years. WRKY transcription factors were first found in sweetpotato (Ishiguro and Nakamura, 1994), and then a large number of WRKY transcription factors, which are a large family of plant transcription factors, were sequentially found in various plants. The WRKY transcription factor is a plant-specific zinc finger-type transcription regulatory factor, and is named because it contains a highly conserved 7 amino acid sequence consisting of WRKYGQK at its N-terminus (Huang et al, 2012).
The WRKY transcription factor has the functions of participating in regulation and control of disease resistance, aging, developmental metabolism, abiotic stress and the like. The WRKY transcription factor is involved in regulating plant senescence, and the transcription factor AtWRKY6 in Arabidopsis is an important transcription factor related to senescence, and is hardly expressed in young leaves and mature leaves, but has a high expression level in senescent leaves (Robatzek., 2002). Arabidopsis AtWRKY53 is used as a positive regulator of leaf senescence, and regulates leaf senescence through a complex regulatory network (Miao et al, 2004). Arabidopsis AtWRKY57 served as a key node of jasmonic and auxin-mediated signaling pathway in jasmonic-induced leaf senescence, and wrky57 mutant produced typical leaf senescence symptoms such as leaf yellowing, low chlorophyll content, and high cell death rate (Jiang et al, 2014).
