AtERF#111/ABR1 is involved in the wounding response

ABSTRACT: AtERF#111/ABR1 belongs to the group X of the ERF/AP2 transcription factor family (GXERFs) and is shoot specifically induced under submergence and hypoxia. It was described to be an ABA-response repressor, but our data hint at a completely different function. Here we present evidence that AtERF#111 is involved in the wounding response. Expression profiling of ERF#111-overexpressing (OE) plants demonstrates that AtERF#111 is a transcriptional activator of wounding response genes. Furthermore, direct target genes of AtERF#111 were identified by microarray analyses. However, knockout mutants of AtERF#111 only show a slightly reduced wounding response, suggesting the involvement of other GXERFs in wound signaling and repair mechanisms.

Microarray data from aerial tissue of submergence tolerant M202(Sub1) and intolerant M202

Project description:An ERF transcription factor, Submergence-1A (Sub1A), dramatically enhances the tolerance to prolonged submergence in rice. For instance, rice accessions which lack Sub1A (e.g. M202) die within 7-10 d of complete submergence. By contrast, genotypes which posses Sub1A (e.g. M202(Sub1)) can endure submergence stress for 14 d. In this study, the two near isogenic lines with and without Sub1A were subjected to microarray analysis using Affymetrix Gene Chip technology. This analysis provided beneficial information to elucidate general response to submergence stress and to estimate Sub1A-dependent defense response to the stress at mRNA accumulation level.

Expression data from Arabidopsis Col-0 expressing FLAG-SUB1A or FLAG-SUB1C rice ERFs

Project description:In rice (Oryza sativa L.), the haplotype at the multigenic SUBMERGENCE 1 (SUB1) locus determines survival of prolonged submergence. SUB1 encodes two or three group VII Ethylene Response Factor (ERF) family transcription factors, SUB1A, SUB1B and SUB1C. A highly submergence-inducible SUB1A allele is present in lines that are submergence tolerant. This gene is the determinant of submergence tolerance. Here, the heterologous ectopic expression of rice SUB1A and SUB1C in Arabidopsis thaliana was employed to assess the transcriptional network mobilized by ectopic expression of SUB1A and SUB1C.

The Submergence Tolerance Regulator Sub1A Mediates Stress-responsive Expression of AP2/ERF Transcription Factors

Project description:Rice NSF45K microarray experiment to dissect submergence tolerance response in submergence tolerant rice plant, M202(Sub1): We previously characterized the rice (Oryza sativa L.) Sub1 locus encoding three Ethylene Responsive Factor (ERF) transcriptional regulators. Genotypes carrying the Sub1A-1 allele are tolerant of prolonged submergence. To elucidate the mechanism of Sub1A-1 mediated tolerance, we performed transcriptome analyses comparing the temporal submergence response of Sub1A-1 containing tolerant M202(Sub1) with the intolerant isoline M202 lacking this gene at three duration of submergence (0d, 1d, and 6d) with two biological replicates and one or two dye-swaps. We identified 898 genes displaying Sub1A-1-dependent regulation. Keywords: Abiotic stress tolerance response

WIND1 orchestrates wound-induced callus formation, vascular reconnection and defense response in Arabidopsis

Project description:Wounding triggers de novo organogenesis, vascular reconnection and defense response but how wound stress evokes such a diverse array of physiological responses remains unknown. We previously identified an AP2/ERF transcription factor, WOUND INDUCED DEDIFFERENTIATION1 (WIND1), as a key regulator of wound-induced cellular reprogramming in Arabidopsis. To understand how WIND1 promotes downstream events, we performed time-course transcriptome analyses after WIND1 induction. We observed a significant overlap between WIND1-induced genes and genes implicated in cellular reprogramming, vascular formation and pathogen response. We demonstrated that WIND1 induces several reprogramming genes to promote callus formation at wound sites. We, in addition, showed that WIND1 promotes tracheary element formation, vascular reconnection and flagellin-triggered defense responses. These results indicate that WIND1 functions as a master regulator of wound-induced responses by promoting dynamic transcriptional alterations. This study provides deeper mechanistic insights into how plants control multiple physiological responses after wounding.
