Journal ArticleDOI
When Defense Pathways Collide. The Response of Arabidopsis to a Combination of Drought and Heat Stress
Ludmila Rizhsky,Hongjian Liang,Joel L. Shuman,Vladimir Shulaev,Sholpan Davletova,Ron Mittler +5 more
TL;DR: In this paper, the response of Arabidopsis plants to a combination of drought and heat stress was found to be distinct from that of plants subjected to either drought or heat stress, and the authors highlighted the plasticity of the plant genome and demonstrate its ability to respond to complex environmental conditions that occur in the field.
Journal ArticleDOI
The Combined Effect of Drought Stress and Heat Shock on Gene Expression in Tobacco
TL;DR: It is demonstrated that the response of plants to a combination of drought and heat shock, similar to the conditions in many natural environments, is different from the response to each of these stresses applied individually, as typically tested in the laboratory.
Journal ArticleDOI
Cytosolic ascorbate peroxidase 1 is a central component of the reactive oxygen gene network of Arabidopsis.
Sholpan Davletova,Ludmila Rizhsky,Hongjian Liang,Zong Shengqiang,David J. Oliver,Jesse Coutu,Vladimir Shulaev,Karen Schlauch,Ron Mittler +8 more
TL;DR: This study points to a key role for the cytosol in protecting the chloroplast during light stress and provides evidence for cross-compartment protection of thylakoid and stromal/mitochondrial APXs by cytosolic APX1.
Journal ArticleDOI
The Zinc Finger Protein Zat12 Is Required for Cytosolic Ascorbate Peroxidase 1 Expression during Oxidative Stress in Arabidopsis
TL;DR: The results suggest that Zat12 is an important component of the oxidative stress response signal transduction network of Arabidopsis required for Zat7, WRKY25, and Apx1 expression during oxidative stress.
Journal ArticleDOI
Double antisense plants lacking ascorbate peroxidase and catalase are less sensitive to oxidative stress than single antisense plants lacking ascorbate peroxidase or catalase
Ludmila Rizhsky,Elza Hallak-Herr,Frank Van Breusegem,Shimon Rachmilevitch,Jason E. Barr,Steven R. Rodermel,Dirk Inzé,Ron Mittler +7 more
TL;DR: The results suggest that a co-ordinated induction of metabolic and defense genes, coupled with the suppression of photosynthetic activity, can compensate for the lack of APX and CAT, and demonstrate that the plant genome has a high degree of plasticity and will respond differently to different stressful conditions.
