“…71,72 Though the later share the resistance profile with the ABA induced genes, the CBF/DREB transcription factors are independent of ABA signals. 73 Interestingly Franklin et al demonstrated that CBF1, CBF2 and CBF3 expression was increased under a low R/FR ratio (increased far-red light), which is typically present under a canopy or other shading. After experiencing a low R/FR illumination, plants acquired freezing tolerance.…”

“…These kinds of land surface drying affects plant available water leading to drought stress, which affects plant growth and productivity of major crop plants (Rampino et al 2006;Reddy et al 2004;Bartels and Sunkar 2005). Water deficit triggers a cascade of physiological, biochemical and molecular alterations in plants resulting in adaptive responses (Urano et al 2010;Reddy et al 2004). At physiological level, drought affects CO 2 assimilation rates and synthesis of photosynthetic pigments (Jaleel et al 2009;Reddy et al 2004), induces production of reactive oxygen species (ROS)leading to oxidative damage which can be measured by the level of lipid peroxidation (Cruz de Carvalho 2008).…”

The current study analyses few important biochemical parameters and microRNA expression in two closely related species (wild but tolerant Ipomoea campanulata L. and cultivated but sensitive Jacquemontia pentantha Jacq.G.Don) exposed to water deficit conditions naturally occurring in the field. Under soil water deficit, both the species showed reduction in their leaf area and SLA as compared to well-watered condition. A greater decrease in chlorophyll was noticed in J. pentantha (~50 %) as compared to I. campanulata (20 %) under stress. By contrast, anthocyanin and MDA accumulation was greater in J. pentantha as compared to I. campanulata . Multiple isoforms of superoxide dismutases (SODs) with differing activities were observed under stress in these two plant species. CuZnSOD isoforms showed comparatively higher induction (~10-40 %) in I. campanulata than J. pentantha . MicroRNAs, miR398, miR319, miR395 miR172, and miR408 showed opposing expression under water deficit in these two plant species. Expression of miR156, miR168, miR171, miR172, miR393, miR319, miR396, miR397 and miR408 from either I. campanulata or J. pentantha or both demonstrated opposite pattern of expression to that of drought stressed Arabidopsis. The better tolerance of the wild species (I. campanulata) to water deficit could be attributed to lesser variations in chlorophyll and anthocyanin levels; and relatively higher levels of SODs than J. pentantha. miRNA expression was different in I. campanulata than J. pentantha.

“…Among the latter, drought, salinity, extreme temperatures, anoxia, excess light, xenobiotics, and heavy metals dramatically affect plant growth and development as well as crop yield (Jaspers and Kangasjärvi, 2010;Urano et al, 2010;Kosová et al, 2011). Plants have developed sophisticated signaling mechanisms that link the perception of the stress signals to specific responses, such as up-or down-regulation of stressresponsive genes (Yamaguchi-Shinozaki and Shinozaki, 2006).…”

Nuclear Accumulation of Cytosolic Glyceraldehyde-3-Phosphate Dehydrogenase in Cadmium-Stressed Arabidopsis Roots

et al. 2013

NAD-dependent glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a ubiquitous enzyme involved in the glycolytic pathway. It has been widely demonstrated that mammalian GAPDH, in addition to its role in glycolysis, fulfills alternative functions mainly linked to its susceptibility to oxidative posttranslational modifications. Here, we investigated the responses of Arabidopsis (Arabidopsis thaliana) cytosolic GAPDH isoenzymes GAPC1 and GAPC2 to cadmium-induced stress in seedlings roots. GAPC1 was more responsive to cadmium than GAPC2 at the transcriptional level. In vivo, cadmium treatments induced different concomitant effects, including (1) nitric oxide accumulation, (2) cytosolic oxidation (e.g. oxidation of the redox-sensitive Green fluorescent protein2 probe), (3) activation of the GAPC1 promoter, (4) GAPC1 protein accumulation in enzymatically inactive form, and (5) strong relocalization of GAPC1 to the nucleus. All these effects were detected in the same zone of the root tip. In vitro, GAPC1 was inactivated by either nitric oxide donors or hydrogen peroxide, but no inhibition was directly provided by cadmium. Interestingly, nuclear relocalization of GAPC1 under cadmium-induced oxidative stress was stimulated, rather than inhibited, by mutating into serine the catalytic cysteine of GAPC1 (C155S), excluding an essential role of GAPC1 nitrosylation in the mechanism of nuclear relocalization, as found in mammalian cells. Although the function of GAPC1 in the nucleus is unknown, our results suggest that glycolytic GAPC1, through its high sensitivity to the cellular redox state, may play a role in oxidative stress signaling or protection in plants.
