TL;DR: PYR/PYLs are ABA receptors functioning at the apex of a negative regulatory pathway that controls ABA signaling by inhibiting PP2Cs, illustrating the power of the chemical genetic approach for sidestepping genetic redundancy.
Journal ArticleDOI
Regulation of Abscisic Acid Signaling by the Ethylene Response Pathway in Arabidopsis
TL;DR: It is concluded that ethylene appears to be a negative regulator of ABA action during germination, while the ethylene response pathway positively regulates some aspects of A BA action that involve root growth in the absence of ethylene.
Journal ArticleDOI
Fatty acid composition of leaf lipids determined after combined digestion and fatty acid methyl ester formation from fresh tissue
TL;DR: A procedure which uses hot methanolic HCl to digest fresh tissue and simultaneously convert the fatty acids of the leaf lipids to the corresponding methyl esters is described, providing a fatty acid analysis which is comparable to that obtained by a more conventional technique, but the overall yield is reduced by 10-20%.
Journal ArticleDOI
A Protein Farnesyl Transferase Involved in Abscisic Acid Signal Transduction in Arabidopsis
TL;DR: A collection of mutations, designated era, in Arabidopsis thaliana that confer an enhanced response to exogenous ABA includes mutations in the Era1 gene, which encodes the β subunit of a protein farnesyl transferase.
Journal ArticleDOI
A Role for Brassinosteroids in Germination in Arabidopsis
Camille M. Steber,Peter McCourt +1 more
TL;DR: It is shown that BR rescues the germination phenotype of severe GA biosynthetic mutants and of the GA-insensitive mutant sleepy1, and this result shows that BR stimulates germination and raises the possibility that BR is needed for normal germination.
