Regulation and role of the Arabidopsis abscisic acid-insensitive 5 gene in abscisic acid, sugar, and stress response.
Abscisic acid (ABA) and stress response from late embryonic growth through early seedling development is regulated by a signaling network that includes the Arabidopsis ABA-insensitive (ABI)5 gene, which encodes a basic leucine zipper transcription factor. We have characterized genetic, developmental, and environmental regulation of ABI5 expression. Although expressed most strongly in seeds, the...
متن کاملThree genes that affect sugar sensing (abscisic acid insensitive 4, abscisic acid insensitive 5, and constitutive triple response 1) are differentially regulated by glucose in Arabidopsis.
Mutant characterization has demonstrated that ABI4 (Abscisic Acid [ABA] Insensitive 4), ABI5 (ABA Insensitive 5), and CTR1 (Constitutive Triple Response 1) genes play an important role in the sugar signaling response in plants. The present study shows that the transcripts of these three genes are modulated by glucose (Glc) independently of the developmental arrest caused by high Glc concentrati...
متن کاملInteraction of osmotic stress, temperature, and abscisic acid in the regulation of gene expression in Arabidopsis.
The impact of simultaneous environmental stresses on plants and how they respond to combined stresses compared with single stresses is largely unclear. By using a transgene (RD29A-LUC) consisting of the firefly luciferase coding sequence (LUC) driven by the stress-responsive RD29A promoter, we investigated the interactive effects of temperature, osmotic stress, and the phytohormone abscisic aci...
متن کاملGene expression in response to abscisic acid and osmotic stress.
Abscisic acid (ABA) was discovered in the 1950s to be a phytohormone affecting leaf abscision and bud dormancy. It was soon characterized as a sesquiterpene derived from mevalonate although certain steps of its biosynthesis in plants are still unknown (Li and Walton, 1987; Zeevaart and Creelman, 1988). Continuing work on ABA has shown that it mediates various developmental and physiological pro...
متن کاملAbscisic Acid (ABA) Regulation of Arabidopsis SR Protein Gene Expression
Serine/arginine-rich (SR) proteins are major modulators of alternative splicing, a key generator of proteomic diversity and flexible means of regulating gene expression likely to be crucial in plant environmental responses. Indeed, mounting evidence implicates splicing factors in signal transduction of the abscisic acid (ABA) phytohormone, which plays pivotal roles in the response to various ab...
