Transcription profiling of rice wild type Zhonghua11 and mutant gif1 in filling stage


ABSTRACT: To reveal the underlying molecular mechanism of Gif1 action in the control of grain filling and yield improvement, we performed transcriptional profiling of wild type Zhonghua11 and mutant gif1 plants in early filling stage on a global scale using the Affymetrix GeneChip Rice Genome Array Experiment Overall Design: Rice caryopsis were harvested in 7 days after flowering and three biological repeats were performed on Zhonghua11 (wild-type) and gif1 (mutant), respectively.

Grain-filling, an important trait that contributes greatly to grain weight, is regulated by quantitative trait loci and is associated with crop domestication syndrome. However, the genes and underlying molecular mechanisms controlling crop grain-filling remain elusive. Here we report the isolation and functional analysis of the rice GIF1 (GRAIN INCOMPLETE FILLING 1) gene that encodes a cell-wall invertase required for carbon partitioning during early grain-filling. The cultivated GIF1 gene shows  ...[more]
