Gibberellin signalling mediates nucleocytoplasmic trafficking of Sucrose Synthase 1 to regulate the drought tolerance in rice.

The Green Revolution (GR) has substantially improved cereal crop yields and enhanced adaptation to diverse environmental challenges. However, the molecular and cellular mechanisms involving GR-related genes that regulate drought tolerance in plants remain largely unclear. Here, we reveal that the gibberellin (GA) signalling repressor SLENDER RICE 1 (SLR1) negatively regulates the abundance of the dehydration-responsive protein OsBURP3 to enhance drought tolerance in rice.

Genome-Wide Identification, Expansion Mechanism and Expression Profiling Analysis of Gene Family in Gramineae Crops.

The gene family encodes a typical transcription factor containing a noncanonical Leucine (Leu-)-zipper motif that plays an essential role in regulating plant growth and development, as well as responding to various stresses. However, limited information on the gene family is available in the case of the Gramineae crops. Here, 125 genes from nine Gramineae crops species were phylogenetically classified into four clades using bioinformatics analysis.
