ITRAQ-based quantitative proteomic and physiological analysis of the response to N deficiency and the compensation effect in rice.

ABSTRACT:

Background

The crop growth compensation effect is a naturally biological phenomenon, and nitrogen (N) is essential for crop growth and development, especially for yield formation. Little is known about the molecular mechanism of N deficiency and N compensation in rice. Thus, the N-sensitive stage of rice was selected to study N deficiency at the tillering stage and N compensation at the young panicle differentiation stage. In this study, a proteome analysis was performed to analyze leaf differentially expressed proteins (DEPs), and to investigate the leaf physiological characteristics and yield under N deficiency and after N compensation.

Results

The yield per plant presented an equivalent compensatory effect. The net photosynthetic rate, optimal/maximal quantum yield of pho
