Transcriptional profiling by array of Arabidopsis ABA auxotroph to identify early downstream targets of transcription in response to a small dose of abscisic acid (ABA)

ABSTRACT: Abscisic acid (ABA) is a plant hormone that is important in responding to various environmental stresses. Using an ABA auxotroph in Arabidopsis (aba2-2) as the plant material, we would like to identify early downstream targets of transcription in response to a small dose of ABA, 1 uM. We also added cycloheximide to preferentially obtain immediate targets of ABA addition. We believe that using a sensitized background of an ABA auxotroph would yield a set of genes that are very closely regulated by ABA at the transcriptional level. This data set will be used for network analysis of ABA signaling.

Expression data of T87 Arabidopsis cultured cells in the presence of ABA, SA, JA, ABA+SA, or ABA+JA for 3hr or 24hr

Project description:Plant hormones involved in environmental stresses, namely abscisic acid (ABA), salicylic acid (SA), and jasmonic acid (JA), have been shown to interact with each other in a complex manner. To address the network of the hormone interactions, we have investigated the changes in expression under multiple hormone treatments, ABA+SA and ABA+JA. We chose cultured cells to remove the difference in the response to hormones among developmental cells or tissues. The cells were treated for 3hr and 24hr to see the rapid or transient response and steady-state response. The obtained data indicate that ABA and SA affect antagonistically, but these hormones affected many genes collaboratively. Indeed, according to the microarray data, there are many genes that responded only to ABA+SA. In addition, the ABA+SA responsive genes also responded to ABA+JA. These data suggest that hormone crosstalk is more complicated than expected and that more systematic analysis is required to untangle the hormone crosstalk network. To investigate the hormonal interactions, Arabidopsis T87 cultured cells were exposed to ABA, SA, or JA alone, or two hormones simultaneously, ABA+SA or ABA+JA, for 3hr and 24 hr. Comparing the data among those treatments, the relationships among these hormones were deduced.

A novel NAC transcription factor cooperates with bZIP-type transcription factors in dehydration and osmotic stress responses

Project description:Multiple transcription factors (TFs) play essential roles in plants under abiotic stress, one of the most challenging conditions of plant survival. However, how these multiple TFs cooperate in abiotic stress responses still remains largely unknown. In this study, we provide evidence that a novel NAC (NAM, ATAF1/2, and CUC2) transcription factor (ANAC096) cooperates with bZIP-type TFs [ABRE-binding factor/ABRE-binding protein (ABF/AREB)] in ensuring survival under dehydration and osmotic stress conditions. Intriguingly, ANAC096 directly interacted with ABF2 and ABF4, but not with ABF3, both in vitro and in vivo. ANAC096 and ABF2 synergistically activated RD29A transcription. The genome-wide gene expression analysis revealed that a major proportion of ABA-responsive genes are under the transcriptional regulation of ANAC096.An Arabidopsis mutant, anac096, was hyposensitive to exogenous abscisic acid (ABA), and showed impaired ABA-induced stomatal closure and increased water loss under dehydration stress conditions. Furthermore, the anac096 abf2 abf4 triple mutant was much more sensitive to dehydration and osmotic stresses than the anac096 single mutant or the abf2 abf4 double-mutant. Based on these results, we propose that ANAC096 is involved in a synergistic relationship with a subset of ABFs for the transcriptional activation of ABA-inducible genes in response to dehydration and osmotic stresses. pTA plants (12-day-old) cultured in liquid medium were treated with 30 uM Dex alone for 1 h (Control) or 30 uM Dex alone for 30 min followed by an additional treatment of 30 min with both 30 uM Dex and 2 uM ABA (ABA). For pTA-ANAC096 plants, 12-day-old seedlings were treated with 30 uM Dex for 1 h (ANAC096) or with 30 uM Dex only for 0.5 h followed by additional 0.5 h incubation with both 2 uM ABA and 30 uM Dex (ANAC096+ABA). Total RNAs were isolated from two biological replicates at each condition and used to measure gene expression level.

Abscisic acid (ABA) application to Populus × canescens in hydroponics

Project description:4 weeks old rooted plantlets of P. × canescens (Clone INRA717 1-B4) were cultivated in hydroponics in 2 l pots in Long Ashton nutrient solution in a culture room for 8 weeks before treatments started. Three treatments were applied to the plants: control treatment (-ABA), continuous 100 µM ABA treatment (+ABA) and discontinuous 100 µM ABA treatment (±ABA). ABA was fed to +ABA plants during the whole treatment period of 30 days. ABA was fed to ±ABA plants for three days in two weeks. Developing xylem and mature xylem were collected separately during the harvest and shortly frozen in liquid nitrogen. RNA was extracted from these samples and followed by RNA-sequencing.
