Summary: The study focused on screening drought-tolerant sugarcane cultivars using PEG as a stressing agent. Results showed varying responses in different cultivars, with Mex 69-290 exhibiting tolerance to osmotic stress. Overall, total protein content decreased while dry matter, proline, and glycine-betaine contents increased with higher PEG concentrations. This suggests Mex 69-290 could be a suitable choice for rainfed cultivation with low water availability.

Summary: This study investigated the impact of exogenous supplementation of hydrogen sulfide (HS) on the growth, enzyme activity, chlorophyll pigments, and tolerance mechanisms in salinity-stressed wheat. The results showed that HS supplementation increased the growth attributes of wheat and mitigated the decline caused by salt stress. HS supplementation also enhanced antioxidant enzyme activity, reduced lipid peroxidation, and increased the content of reduced glutathione. Furthermore, HS supplementation increased the levels of proline and glycine betaine, reduced sodium levels, and increased potassium levels. However, under salt stress, HS supplementation led to a reduction in hydrogen sulfide and nitric oxide levels.

Summary: The control of chilling injury in peach fruit by a new regulator network involving exogenous gamma-aminobutyric acid (GABA), polyamines (PAs), the GABA shunt, and proline remains unclear. This study found that GABA induced an increase in PpADC and PpODC expression, resulting in the accumulation of PAs. It also led to increased GABA and proline content through increased expression of PpGAD and PpP5CS/PpOAT, respectively.

Summary: Nitric oxide (NO) and abscisic acid (ABA) synergistically reduce the heat stress effects on photosynthesis and growth by reducing oxidative damage and increasing osmolyte production and antioxidant activity. Inhibition of NO and ABA decreases heat stress tolerance, suggesting the dependence of ABA function on NO. Regulation of antioxidant enzymes and osmolyte production may serve as a strategy for heat tolerance.

Summary: Salt stress is a major problem affecting agricultural productivity worldwide, with 20% of arable lands and 33% of irrigated areas already affected by soil salinity. This study aimed to investigate the effect of osmolytes on soybean growth under salt stress. The results showed that supplementation of osmoprotectants, particularly 20 mM proline, improved soybean tolerance to salinity stress by enhancing growth, physiological response, antioxidant activity, and reducing lipid peroxidation. Among the genotypes tested, the Ajmeri genotype showed the most promising outcomes.

Summary: Drought causes more loss in crop yield than all other environmental stresses combined. There is growing interest in using stress-resilient PGPR to enhance plant resistance and crop productivity in drought-affected agroecosystems. By studying the physiological and biochemical responses of PGPR under drought conditions, we can gain insights into stress adaptation mechanisms and potentially engineer PGPR to improve drought tolerance in plants.

Summary: In situ testing in coral-reef communities allows the evaluation of fish species' behavioral responses in their natural environments. This study introduces a new method of odorant release using gravity as a motive force, allowing odorant-containing water to be ejected silently and remotely over an extended period of time. The observations suggest that brown chromis may be attracted to DMSP, while creole wrasse and yellowhead wrasse may be repelled by DMSP. Many other fish species show no evidence of being affected by either DMSP or betaines.

Summary: Salinity is an environmental factor that reduces plant productivity, but modifying Ca2+ cation exchangers (CAX) transporters could increase plant tolerance to salinity. Through Targeting Induced Local Lesions in Genomes (TILLING), researchers generated mutants of Brassica rapa CAX1a transporter, with BraA.cax1a-4 showing improved photosynthetic performance under saline conditions. This study highlights BraA.cax1a-4 as a useful mutation for enhancing photosynthesis in plants grown in saline conditions.

Summary: Capnophilic lactic fermentation (CLF) is an anaplerotic pathway identified in Thermotoga bacteria that enables non-competitive synthesis of hydrogen and L-lactic acid. This study discovered and characterized CLF in Thermotoga sp. strain RQ7, opening up new possibilities for molecular investigation of the pathway. Key CLF enzymes are up-regulated in the CLF-performing strains, and the up-regulation of V-ATPase plays a crucial role in supporting the simultaneous synthesis of hydrogen and lactic acid.
