Abstract The plant hormone abscisic acid (ABA) controls many aspects of plant growth and development under a diverse range of environmental conditions. To identify genes functioning in ABA signaling, we have carried out a screen for mutants that takes advantage of the ability of wild-type Arabidopsis seeds to respond to (−)-(R)-ABA, an enantiomer of the natural (+)-(S)-ABA. The premise of the screen was to identify mutations that preferentially alter their germination response in the presence of one stereoisomer vs. the other. Twenty-six mutants were identified and genetic analysis on 23 lines defines two new loci, designated CHOTTO1 and CHOTTO2, and a collection of new mutant alleles of the ABA-insensitive genes, ABI3, ABI4, and ABI5. The abi5 alleles are less sensitive to (+)-ABA than to (−)-ABA. In contrast, the abi3 alleles exhibit a variety of differences in response to the ABA isomers. Genetic and molecular analysis of these alleles suggests that the ABI3 transcription factor may perceive multiple ABA signals.

AbstractAn Arabidopsis mutant named defective repression of OLE3::LUC 1 (drol1) was originally isolated as a mutant with defects in the repression of OLEOSIN3 (OLE3) after seed germination. In this study, we show that DROL1 is an Arabidopsis homolog of yeast DIB1, a subunit of U5 snRNP in the spliceosome, but comprises a subfamily specific to a certain class of eukaryotes. Comprehensive analysis of intron splicing by RNA-Seq analysis of drol1 mutants revealed reduced splicing of most of the minor introns with AT–AC dinucleotide termini. Thirty-nine genes, including those playing important roles in the response to abiotic stress, exhibited reduced splicing of AT–AC-type introns in drol1 mutants. In addition, drol1 mutant seedlings showed growth arrest, similar to that caused by the activation of abscisic acid signaling, as a result of reduced splicing of AT–AC-type introns in some genes. These results indicate that DROL1 is specifically involved in the splicing of introns with AT–AC termini, and splicing of these minor introns plays an important role in plant growth and development.

<p>Free abscisic acid (ABA) and bound abscisic acid (ABA-GE: ABA glucose ester) contents and growth were investigated in leaves, internodes, flowers buds, flowers and berries of <em>Vitis vinifera</em> L. cv. Cabernet Sauvignon between flower buds separated and grape closed stages. The ABA levels in leaves and in internodes decrease when the growth was hight and increases when the growth become smaller or stopped. What is more, ABA was accumulated hightly in the flowers (at 50% of flowering) and then appears to be a good marker of flowering. ABA contents decreased at berry setting and till grape closed stage. In leaves, internodes, flowers buds and flowers, ABAGE and ABA show an inverse development and then suggests an interconversion phenomenon between theses two forms. Two most importants points were discuted in this paper: 1) The role of ABA in the controle of growth and development of the organs studied and (2) The translocation of abscisic acid between the organs studied and the role of ABA-GE in this transport.</p>
