Arabidopsis heat shock transcription factor A2 as a key regulator in response to several types of environmental stress
Abstract
Summary: We isolated 76 high‐light and heat‐shock (HL + HS) stress‐inducible genes, including a putative heat‐shock transcription factor ( HsfA2 ), by suppression‐subtractive hybridization from Arabidopsis. The transcript level of HsfA2 was significantly increased under the several stress conditions or by the H 2 O 2 treatment. Furthermore, the induction of HsfA2 expression was highest among those of other class A HSFs in response to HL + HS stress conditions. The promoter assay revealed that HsfA2 is induced mainly in rosette leaves under HL + HS stress conditions. In the HsfA2 ‐overexpressing Arabidopsis ( Pro 35 S :HsfA2 ) plants, 46 genes, including a large number of heat‐shock proteins, ascorbate peroxidase 2 and galactinol synthase 1 and 2, were highly expressed compared with those in the wild‐type plants. The transcript levels of the HsfA2 target genes are highly correlated with those of HsfA2 in the Pro 35 S :HsfA2 plants. The transcript levels of the HsfA2 target genes, as well as HsfA2 transcripts, were induced by treating with exogenous H 2 O 2 . In the knockout HsfA2 Arabidopsis plants, the induction of 26 HsfA2 target genes was strongly reduced for up to 2 h under HL + HS stress conditions. Furthermore, the Pro 35 S :HsfA2 plants showed increased tolerance to combined environmental stresses. Our present results indicate that HsfA2 is a key regulator in the induction of the defence system under several types of environmental stress.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
