TL;DR: This review discusses the dual action of AOS during plant stress responses, which was first described in pathogenesis but has also recently been demonstrated during several abiotic stress responses.

TL;DR: H2O2 was inferred to play a key role in the transcriptional up-regulation of small heat shock proteins during high light stress and a transcriptional cluster that was strongly and rapidly induced by high light in control plants, but impaired in catalase-deficient plants was identified.

TL;DR: Microarray analysis on both control and transgenic catalase-deficient plants, exposed to 0, 3, 8, and 23 h of HL, revealed several specific regulatory patterns of gene expression that indicate photorespiratory H(2)O(2), which has a direct impact on transcriptional programs in plants.

TL;DR: Investigation of the expression kinetics of catalase-deficient tobacco plants exposed to high light intensities showed that HL induced photoinhibition in CAT1AS plants and that a short-term HL exposure of CAT1as plants triggered an increased tolerance against a subsequent severe oxidative stress.

TL;DR: It is indicated that chilling temperatures affect the bacterial community composition within the maize root endosphere, and two promising strains that promoted maize growth under chilling conditions were identified that belonged to the root endophytic bacterial families, from which the relative abundance remained unchanged by variations in the growth temperature.
