Abstract

The Chlorophyll Biosynthesis and Degradation and Chloroplast Structure in Tomato Yellow Mutant

Highlights

  • Most plants are mainly green in nature

  • It was crossed with zs4 to produce F1, F2 progeny for agronomic trait analyses

  • Chlorophyll a (Chla) and chlorophyll b (Chlb) content were measured by the spectrophotometric

Summary

Introduction

Most plants are mainly green in nature. The chlorophyll content is one of the important determinants of leaf color. The silencing or inactivation of major genes role in chlorophyll bio-synthesis could cause the plant leaves color faded green [21]. Coschigano, et al [22] identified the GLUI gene from the Arabidopsis leaf color mutant gls and proved the GLUI was associated with photorespiration [22] This discovery provides a new way to improve crop yield by inhibiting the photorespiration of C3 crops to increase photosynthetic efficiency. The study of leaf color mutants can improve the understanding of plant photosynthesis and the role of chlorophyll in the presence of plants. We focus on the chlorophyll biosynthesis or degradation pathways which cause the leaf color change to yellow in tomato mutant ym.
