Abstract
Identification and Gene Mapping of A White Panicle Mutant <i>wp7</i> in Rice
Highlights
White panicle mutant of rice can be used to study the mechanism of chloroplast development and photosynthesis of pancile, and to improve and optimize the yield characteristics of grain crops
Transmission electron microscope (TEM) observation showed that the plastids in white part of wp7 were few in number and abnormal in structure, without normal thylakoid lamella, and the chloroplast lamellar structure in green part was slightly abnormal, which indicated that mutations had a great influence on chloroplast development
1.2 Glume chloroplast structure of white panicle wp7 In order to find out the cytological reasons of glume albino, the wp7 white part, green part and chloroplast of
Summary
White panicle mutant of rice can be used to study the mechanism of chloroplast development and photosynthesis of pancile, and to improve and optimize the yield characteristics of grain crops. A white panicle mutant wp7 (whited panicle 7) which found in rice breeding materials was used to do related work from phenotype investigation, chlorophyll content testing, photosynthetic index detection, microscopic structure observation, genetic analysis and gene location. The result showed that wp7 displayed albino glume with green branches and cob at heading stage.
