传统上,抗病基因Pi-ta被认为通过编码一种含有核苷酸结合和亮氨酸丰富重复结构域的蛋白质(NLR),直接识别AVR-Pita。然而,本研究颠覆了这一观念,揭示Pi-ta抗性实际上依赖于非传统抗性基因Ptr。 通过对水稻中的NLR Pi-ta和Ptr进行RNA干扰和CRIS...
这些菌株均属于多核丝核菌类、立枯丝核菌(R.solani)AG 1-IA融合群;致病力测定结果表明,这些菌株的致病力类型有一定的差异,但菌株的生长速率与其致病力之间无... 朱名海 - 华南农业大学 被引量: 1发表: 0年 Ethylene and Plant Immunity Diversification and evolution of the avirulence gene AVR-Pita1 in ...
The objective of this study is to investigate the nucleotide sequence variation of the AVR-Pita1 gene that influences the adaption of rice blast fungus to overcome the resistant gene, Pi-ta. Thirty rice blast fungus isolates were collected in 2005 and 2010 from infected rice plants in northern...

Pita1-transformed isolates were not able to infect rice cultivars Katy and Drew carrying Pi-ta.Control isolates that were transformed with inserts lacking the AVR-Pita1gene remained virulent.Our findings demonstrate that AVR-Pita1 can be used to induce novel gene-specific blast resistance in ...

Genetic variation of the rice blast ( Pyricularia oryzae ) population in Thailand was investigated based on the nucleotide sequence of three avirulence genes, AVR ‐ Pi9 , AVR ‐ Pik , and AVR ‐ Pita1 . Sixty rice blast isolates were collected from rice‐growing areas around Thailand. Gene...
