Summary: In the era of climate change, heat stress poses a serious threat to pea plants, affecting their productivity and germination ability. Pea plants employ various defense strategies to tolerate heat stress, but the specific temperature thresholds and responses are still unknown. Traditional breeding methods and modern genomics technologies can be used to screen and develop heat-tolerant pea genotypes. Precise phenotyping and genomic studies can help identify candidate genes, and transgenic technology can be an alternative approach for developing heat-tolerant pea genotypes.

Summary: Biofortification is an approach to increase micronutrient concentrations in edible parts of plants, with various breeding methods available. Peas, recognized for their nutritional value, have untapped micronutrient potential that needs to be considered in development, ensuring nutrient retention post processing and cooking for improved agricultural productivity.

Summary: This study demonstrates the impact of drought stress on the phloem sap content of Pisum sativum plants, and how these changes are connected to the plant's strategies to cope with water deficit. Results indicate that under drought stress, pea plants undergo metabolic changes in the phloem sap content to adapt to environmental conditions.

Summary: This study aims to investigate the effects of single or combined salinity and drought stresses on physio-biochemical and molecular status of diverse forage pea genotypes. The results showed that the genotypes O14 and T8 were more tolerant to combined stress by activating antioxidative enzymes, endogenous hormones, stress-related genes, and leaf senescence genes. These genotypes could be used to develop pea plants that tolerate salinity or drought stress conditions.

Summary: The study identified a pea homolog gene PsSMXL7, which is related to D53 and SMXL6/SMXL7, and revealed its role in regulating bud outgrowth and integrating SL and CK responses. PsSMXL7, like D53 and related SMXLs, can be degraded by SL and induces feedback upregulation of its transcript, suggesting a conserved system in pea and rice involving SL and CK cross-talk in branching regulation.

Summary: This study evaluated the effects of planting density and row spacing on pea and found that pea is highly sensitive to precipitation deficit. Planting density and row spacing did not significantly affect pea yield, while the highest protein yield was obtained under the hottest and least rainy conditions.

Summary: Understanding the genetic diversity and population structure of pea germplasm is necessary for developing rust resistant varieties. This study analyzed 115 Australian accessions and 4 Indian varieties using 31 polymorphic SSR markers, revealing 78 alleles and three alleles per marker on average. The population structure analysis identified three sub-populations and showed significant variation among the pea entries.

Summary: The study found that pea plants adjust to progressive soil drought by accumulating osmolytes and osmoprotectants, and transferring some of them (proline, sucrose, myoinositol) to the shoot tip, thereby protecting the youngest tissues from damage caused by water deficit.

Summary: The transition from seed to seedling is a crucial step in the plant life cycle. In this study, the authors investigated the changes in water and oxidative status, as well as gene expression, during this transition in Pisum sativum seeds. They found that the accumulation of ROS and the shift in water and oxidative status were correlated with the loss of desiccation tolerance. RNA sequencing analysis revealed differentially expressed genes related to metabolism, photosynthesis, cell wall biosynthesis, redox status, and stress responses. The findings suggest that specific genes, such as LTI65, LTP4, and HVA22E, may play a crucial role in the desiccation tolerance loss during the transition.

Summary: The study showed that drought stress significantly affects seed germination, plant growth, chlorophyll content, GABA shunt metabolites level, total protein and carbohydrate contents, and MDA level in green pea seedlings. It was found that there is a threshold value of 20% soil water holding capacity for normal germination after 14 days. Additionally, severe and long-term drought stress should be avoided during the germination stage to ensure proper seedling growth and metabolism.

Summary: This study successfully isolated and characterized three glycoprotein structures from peas, with PGP2 demonstrating the highest hypoglycemic activity by inhibiting glucose uptake in the small intestine and enzyme activities. Even after simulated gastrointestinal digestion, PGP2 maintained strong hypoglycemic effects, indicating its potential as a functional food or medicine for treating diabetes mellitus.

Summary: This study investigated two CHLI genes in pea and found that PsCHLI1 is the key subunit for Mg-chelatase activity. The peptide fragments of PsCHLI1 are essential for maintaining the activity of Mg-chelatase, which could be manipulated to improve photosynthetic efficiency.

Summary: Pretreatment with calcium and H2S can alleviate the negative effects of Ni on growth of pea seedlings by reducing reactive oxygen species levels and preserving membrane integrity. Calcium treatment also increases catalase activity and reduces Ni absorption and accumulation. This suggests a functional crosstalk between calcium and H2S in conferring pea tolerance to Ni-stress.

Summary: The study aimed to determine the genetic diversity and spatial distribution of five common broadleaved tree species in Lithuania, including both maternal stands and natural regeneration. The results showed that the regenerating populations of these tree species exhibited random genetic structures, while Populus tremula mainly regenerated through root suckers. The genetic diversity in regenerating populations was as high as in maternal stands, indicating their potential to adapt to changing environmental conditions.

Summary: The impact of exogenous calcium, proline, and plant probiotics on the response of winter wheat to drought stress was evaluated and compared in this study. The results showed that all tested compounds improved the prolonged drought tolerance of winter wheat. ProbioHumus and ProbioHumus + Ca had the greatest effect in maintaining the relative leaf water content and growth parameters close to those of irrigated plants.

Summary: The study evaluated the cross-adaptation of wheat and triticale exposed to drought and waterlogging after treatment with the selective herbicide Serrate((R), Syngenta). The herbicide had ambivalent effects on the two crops, with a significant reduction in wheat growth and better performance in triticale individuals. Histochemical staining confirmed increased ROS accumulation in flooded wheat plants, persisting in the younger leaves of the recovered individuals. Transcript profiling revealed crop-specific variations in ROS scavenging enzymes due to the combination of unfavorable water regimes and herbicide treatment. Short-term dehydration was well tolerated by triticale, but its drought resilience was diminished by herbicide application.

Summary: Waterlogging and drought have negative effects on crop growth and productivity. Triticale shows relative tolerance to stress factors. The herbicide Serrate is effective in controlling weeds in cereal crops like triticale and wheat. In this study, triticale plants were subjected to water stress and herbicide treatment, and the response of antioxidants and detoxifying enzymes was evaluated. The results showed that the drought stress had a more severe impact on the plant's antioxidant system compared to waterlogging stress.

Summary: This study evaluated the effect of exogenous proline on the growth, biochemical responses, and recovery of drought-stressed oilseed rape plants after renewed irrigation. The results showed that proline application reduced growth inhibition, maintained water content, and improved chlorophyll accumulation and membrane permeability. After recovery, proline-treated plants had lower H2O2 content and MDA levels, resulting in higher survival rates compared to drought-treated plants. These findings suggest that exogenous proline has beneficial effects on drought adaptation in oilseed rape.

Summary: The impact of increasing cold stress conditions on polyamines, proline, and ethylene metabolism in acclimated and non-acclimated winter oilseed rape was investigated in this study. A decrease in putrescine, spermidine, and spermine content during cold acclimation and at sub-zero temperatures was observed. Intensive changes in ADC2 gene expression, proline, and ethylene levels were seen in non-acclimated plants, with a substantial increase after exposure to -1 °C temperature and a sharp decrease after exposure to -3 °C temperature. These changes were lower or absent in acclimated plants.
