一个水稻类病条纹斑突变体的鉴定和遗传定位
Identification and Genetic Mapping of a Lesion Mimic Stripe Mutant in Rice
摘要
Abstract
A lesion mimic stripe mutant was obtained from the M2 progeny of a japonica variety Jiahua 1 by 60Co γ radiation,temporarily designated as lms1 (lesion mimic stripe 1 ).The mutant displayed lesion mimic in its whole life, and belonged to propagation type.Physiological and histochemistry analysis suggested that the mutant displayed a phenotype of white stripe at a high temperature (30℃) and lesion mimic caused by cell initiative death at a low temperature(20℃ ), respectively.The genetic analysis indicated that the mutant trait was controlled by a single recessive nuclear gene.In addition, using SSR markers and an F2 segregating population derived from two crosses(lms1/9311 and Pei' ai 64S/lms1 ), the lms1 gene was mapped between Indel1 and MM0112-4 with a physical distance of 400 kb on chromosome 6 in rice.关键词
