TL;DR: This review focuses on the ability and strategies of higher plants to respond and adapt to drought stress, including proline and glycine-betaine, as well as the role of abscisic acid under drought stress conditions.

TL;DR: The Wide Dynamic Range Vegetation Index, WDRVI, increases correlation with vegetation fraction by linearizing the relationship for typical wheat, soybean, and maize canopies and enhances the dynamic range while using the same bands as the NDVI.

TL;DR: Results suggest that specific groups of potential signaling molecules may induce tolerance of creeping bentgrass to heat stress by reducing oxidative damage.

TL;DR: In the sense plants, which best resisted the stress, OEC dissociation was bypassed by proline feeding electrons into photosystem 2 (PSII), maintaining an acceptable nicotinamide adenine dinucleotide hydrogen phosphate (NADPH) level, preventing further damage.

TL;DR: Plants are protected against activated oxygen species by the elevated levels of certain antioxidative enzymes, thus avoiding lipid peroxidation during salt exposure and the differential changes in the levels of the isoforms due to NaCl treatment may be useful as markers for recognizing salt tolerance in mangroves.

TL;DR: Water stress resistance could not be associated with higher OA, although the ability of plants to regulate these metabolic and physiological functions could play an important role under harmful conditions.

TL;DR: GB protects both rice seedlings from salinity-induced oxidative stress, particularly in Pokkali and IR-28 under salinity.

TL;DR: Roots are the major sites of Al localization and accumulation of Al promoted oxygen free radicals mediated peroxidation of membranes as evidenced by increased MDA levels and the activities of SOD and peroxidase.

TL;DR: Results indicate that the spring growth period can be divided into three main phases: in the first (dormancy to budbreak), significant losses of C and N proceed mainly via root necrosis, while in the second period (first leaf to the onset of bloom), a strong mobilization of starch occurred for supporting vegetative and reproductive growth.

TL;DR: The data suggest that SA antagonizes Pq effects, via elicitation of an antioxidative response in barley plants, and is highly expressed on DHAR and POX activity.

TL;DR: The results obtained indicated that the mycorrhizal symbiosis had a beneficial effect on the water status and growth of Rosmarinus officinalis plants under water-stress conditions.

TL;DR: It was concluded that Mn-mediated inhibition of rice photosynthesis barely implicates stomatal conductance, as well as the distribution of energy within the photosystems.

TL;DR: The A3-anionic peroxidase isoform could be used as biochemical marker to distinguish and genotypes of E. cretica and seems to be correlated to lignin synthesis in rooting process.

TL;DR: The response to Cd stress shown by this holoparasitic plant was found to be similar to those of non-parasitic plants (hosts) and amelioration of antioxidative systems of C. reflexa in response toCd stress might be playing a protective role, alleviating the damaging effects of ROS, generated during Cd Stress.

TL;DR: It turned out that NaCl salinity and osmotic stress lead to a differential regulation of distinct SOD isoenzymes, which is suggested to play a major role in stress tolerance of S. salsa.

TL;DR: Though this study depicted the malfunction of the major antioxidant system of C. vulgaris under copper stress the test organism was found to survive and grow even at 3.0 microg mL(-1) of Cu treatment, further study is needed to establish the role of proline in metal toxicity regulation.

TL;DR: Results suggest that H2O2 is involved in ABA-induced senescence of rice leaves.

TL;DR: The data presented suggest that spermine accumulation is not a salt tolerance trait and no reduction in leaf injury associated with salt stress in both cultivars.

TL;DR: The results suggest that the induction of acid and ALP under salt stress may be due to a phosphorous deficiency in mangrove Bruguiera parviflora.

TL;DR: The salt sensitivity of rye could be due to low K+ uptake in the presence of a high NaCl concentration, and increasing soluble sugar content did not appear to prevent competition between Na+ and K+.

TL;DR: The results show that SNP behaves differently than the other NO-donors tested; indeed, SNP induces accumulation of ferritin transcripts in Arabidopsis, whereas SNAP inhibits its accumulation.

TL;DR: Results indicate that in rice seedlings arsenic toxicity causes perturbations in carbohydrate metabolism leading to the accumulation of soluble sugars by altering enzyme activity, possibly plays a positive role in synthesis of sucrose under As-toxicity.

TL;DR: The effects of Mn nutrition of tomato seedlings on Mn-, Fe- and CuZn-superoxide dismutase (SOD, EC 1.15.1) enzymatic activities, metal translocation, chlorophyll concentration, and plant growth were tested to suggest that growth inhibition and chlorophyLL synthesis were affected primarily by manganese deficiency and excess.

TL;DR: Alterations in the metabolism of Lupinus albus organs that result from and following a period of severe water deficit (WD) are described, since proline (a stress related metabolite) disappeared rapidly while sugars and asparagine reached the initial pattern more slowly, particularly in the stem.

TL;DR: The results indicate a strong metabolic co-ordination between PAs and Pro pathways and suggest that the metabolic fluxes through these pathways start competing only when the stress level is high enough to be lethal for cells.

TL;DR: Under conditions of severe water deficit, the most sensitive cultivar exhibited a marked increase in the activity of two different aminopeptidases, while the more resistant cultivar showed a significant decrease in theactivity of these aminopes, pointing to complex and probably specific roles in the plant response to drought.

TL;DR: It was evident that glycolytic flux in apple was dependent on glucose level, and that the reaction catalysed by phosphoglucomutase contributed to the regulation of carbon partitioning between malate and carbohydrate polymers.

TL;DR: Overall, mutant nodules showed lower antioxidant enzyme activities than wild-type nodules, and levels of nodule catalase appeared to correlate with symbiotic nitrogen-fixing efficiency.

TL;DR: Results indicate that BPH feeding induces plant responses which would take part in a jasmonic acid-independent pathway and crosstalk with those related to abiotic stress, pathogen invasion and phytohormone signaling pathways.

TL;DR: The protective effect of PBN on MJ-promoted senescence,MJ-increased H2O2 content and lipid peroxidation, MJ-decreased GSH and AsA, and MJ-increases antioxidative enzyme activities was reversed by 2-(4-carboxy-2-phenyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide, suggesting that the protective effect
