The Function of the Early Trichomes Gene in Arabidopsis and Maize.

Description: Lateral organ polarity in Arabidopsis is regulated by antagonistic interactions between genes that promote either adaxial or abaxial identity, but the molecular basis of this interaction is largely unknown. We show that the adaxial regulator ASYMMETRIC LEAVES2 (AS2) is a direct target of the abaxial regulator KANADI1 (KAN1), and that KAN1 represses the transcription of AS2 in abaxial cells. Mutation of a single nucleotide in a KAN1 binding site in the AS2 promoter causes AS2 to be ectopically e… more

Characterization of Arabidopsis Genes Involved in Gene Silencing. Final Progress Report

Description: Enhancer of gene silencing 1 (egs1) is an Arabidopsis mutant that enhances post-transcriptional gene silencing of the rolB gene introduced by genetic engineering (transgene). The goal of our proposal was cloning EGS1 based on its map position. Although we screened more than 2000 chromosomes for recombination, we were unable to get closer than 2 cM to the gene. We experienced an unexpected tendency of the post-transcriptionally silenced transgene to switch to a more stable silenced state. This m… more

Ascorbate Peroxidase 1 Plays a Key Role in the Response of Arabidopsis thaliana to Stress Combination

Description: Article conducting proteomic and metabolic analysis of Arabidopsis thaliana plants subjected to a combination of drought and heat stress. The authors identify 45 different proteins that specifically accumulated in Arabidopsis in response to the stress combination. The findings suggest that cytosolic APX1 plays a key role in the acclimation of plants to a combination of drought and heat stress.
