Gibberellins are an important class of plant hormones.They play an important regulatory role in all stages of growth and development of higher plants.The use of mutants to study gibberellin metabolism and signal transduction pathways is currently a research hotspot.This article takes the data of Affymetrix chips of rice as an example,bioinformatics method was used to study rice SLR 1 mutant and mine differentially expressed wild-type genes,thus exploring the expression regulation network of gibberellin signaling pathway-related genes.
