芒果炭疽病及其抗性相关基因研究进展
Research Progress on Anthracnose and Resis-tance Related Genes in Mango
摘要
Abstract
Mango(Mangifera indica L.)is one of the major tropical fruit trees worldwide,and its industry plays a significant role in promoting economic development in tropical regions of China and the globe.Anthracnose is one of the primary diseases affecting mango production,preva-lent in mango-growing areas in home and abroad.It causes damage during both the growth and post-harvest storage stages,severely compromising the economic value of mango fruits.Breeding new mango cultivars with resistance to anthracnose is the most economical and effective approach to address this issue,while understanding the molecular genetic mechanisms underlying mango's resis-tance to anthracnose is essential for accelerating the development of resistant cultivars.In light of this key issue,this paper reviewed recent advances in the study of identification of mango anthrac-nose pathogens,evaluation of anthracnose-resistant germplasm resources,discovery of resistance-related genes,and application of molecular markers.Studies show that Colletotrichum gloeosporioi-des(Penz.)Sace is one of the main pathogens causing mango anthracnose,which can infect all parts of the mango plant,including leaves,young shoots,inflorescences and fruits.A number of mango cultivars with high anthracnose resistance have been bred at home and abroad.In gene re-search,several anthracnose resistance genes have been cloned,including those involved in defense gene expression regulation,metabolic pathway regulation,lignin synthesis,and reactive oxygen scavenging.The genes related to pathogen recognition and signal transduction in mango response to anthracnose infection mainly include RGA2,RPM1,NBS-LRR,NPR1,MiPR10-1,MiPR10-3,and MiPR1A.The proteins encoded by these genes can recognize pathogen proteins,influence plant hormone levels,and regulate the expression of other disease-resistant genes.The members of gene families such as DBB,RAV,Whirly,GeBP and MiMYB are transcriptional regulatory factors,which mainly respond to the infection of Colletotrichum gloeosporioides and play a synergistic or resistant role in the infection of anthracnose pathogen.The genes related to mango defense response include MiCHI,MiARE,MiPR,MiPAL,MiSOD,MiPOD,MiPPO,β-1,3-GLU2,etc.,which are mainly related to reactive oxygen species,hydrolysis of fungal cell wall,and enhancement or reduc-tion of mango resistance to anthracnose.Some progress has also been made in the development and application of molecular markers for mango anthracnose resistance.Furthermore,with addressing certain challenges in the genetic breeding of anthracnose resistant cultivars,this article proposed several strategies:to creat novel anthracnose resistant mango germplasm;to establish a standard-ized system for evaluating mango anthracnose resistance;to integrate genomic functional genes and genome-wide polymorphism markers into an informational platform;to overcome technical hurdles in mango tissue regeneration and genetic transformation;and to establish an efficient mango genetic transformation system.These proposals aimed to provide technical references for further research on mango anthracnose resistance genes and molecular breeding for disease resistance.关键词
