Photosynthetic characteristics of subtending leaves and their relationships with soybean pod development under heat, drought and combined stresses

Xiangbei Du et al.

Summary: This study investigated the impact of long-term drought and short-term heat stress on the photosynthetic characteristics and pod development of soybean. The findings revealed that long-term drought stress had a significant effect on the photosynthetic performance of subtending leaves and pod development, and short-term heat stress exacerbated the negative effects of long-term drought stress.

Stromal Ascorbate Peroxidase (OsAPX7) Modulates Drought Stress Tolerance in Rice (Oryza sativa)

Douglas Jardim-Messeder et al.

Summary: This study found that silencing the OsAPX7 gene in rice does not affect plant growth, redox state, or photosynthesis parameters. However, silenced plants (APX7i) show higher tolerance to drought stress, with a higher ability to maintain stomata aperture and photosynthesis performance compared to non-transformed plants. RNA-seq analyses indicate that the silencing of OsAPX7 does not alter the global expression of genes related to reactive oxygen species metabolism. Additionally, the drought-induced regulation of genes related to proteasome pathway, nitrogen metabolism, and carotenoid metabolism is impaired in APX7i plants. On the other hand, genes associated with flavonoid and tyrosine metabolism are upregulated, while genes related to phytohormone signal transduction and nicotinate and nicotinamide metabolism are downregulated in APX7i during drought stress. These results suggest that OsAPX7 may be involved in signaling transduction pathways related to drought stress response in rice, providing insights into the physiological role of chloroplast APX isoforms.

Strigolactones and abscisic acid interactions affect plant development and response to abiotic stresses

Magdalena Korek et al.

Summary: Strigolactones (SL) are a group of plant hormones that play a role in shaping plant architecture and regulating the plant response to abiotic stresses. Recent research suggests that SL and abscisic acid (ABA) interact with each other and balance their content under normal growth conditions, but the exact mechanisms of their cross-talk, especially in stomatal closure during drought, are still poorly understood.

Comparing the salinity tolerance of twenty different wheat genotypes on the basis of their physiological and biochemical parameters under NaCl stress

Amaneh Ghasemi Masarmi et al.

Summary: The climate has changed dramatically over the past two decades, resulting in increased soil salinity due to rising temperatures and climate change. In this study, we evaluated the effects of salinity on 20 wheat genotypes with different levels of salt tolerance. Our findings showed significant differences in the response of genotypes to salt stress, with sensitive genotypes experiencing decreased chlorophyll index while tolerant genotypes showed increased chlorophyll a and carotenoids. Additionally, various biochemical traits such as protein, proline, lipoxygenase, and reactive thiobarbituric acid levels were found to be increased in all wheat genotypes under salt stress. Plant photosynthetic efficiency was identified as a reliable biomarker for determining salt tolerance in wheat genotypes, while other biochemical traits were not suitable for rapid screening due to their destructive nature and time-consuming process.

Overexpression of the VyP5CR gene increases drought tolerance in transgenic grapevine (V. vinifera L.)

Pingying Zhang et al.

Summary: Proline is an osmotic regulatory substance that accumulates in plants under drought stress. Overexpressing the VyP5CR gene from drought-resistant Chinese wild grape in Arabidopsis thaliana and grapevine improves drought tolerance. The MADS-box transcription factors VyAGL42 and VyMADS23 are identified as upstream regulators of VyP5CR in drought tolerance of grapes.

Mechanisms of Abscisic Acid-Mediated Drought Stress Responses in Plants

Mehtab Muhammad Aslam et al.

Summary: Drought is a major constraint to rain-fed agricultural production, and understanding the mechanisms of ABA-mediated drought responses in plants is critical for ensuring crop yield and global food security. This review highlights the regulation of ABA perception, transcriptional levels of ABA- and drought-related genes, and metabolic pathways to alter drought stress responses in plants.

Effects of Weak- and Semi-Winter Cultivars of Wheat on Grain Yield and Agronomic Traits by Breaking through Traditional Area Planting

Yonggang Ding et al.

Summary: The study shows that breaking through traditional area plantings of wheat cultivars does not significantly increase grain yields, and wheat planted in the northern Yangtze River basin has higher grain yields compared to the southern region due to an increase in spikes resulting from a longer spike formation phase.

Delineation of Physiological, Agronomic and Genetic Responses of Different Wheat Genotypes under Drought Condition

Syed Muhammad Dawood Murtaza Shah et al.

Summary: Abiotic stress such as drought poses a severe challenge to wheat production. This study compared the performance of different Pakistani bread wheat genotypes at physiological, agronomic, and genetic levels. The results showed significant alterations in physiological and agronomic traits under drought stress, with variations among genotypes. Correlation analysis revealed significant changes in the association of traits among genotypes during drought stress. Additionally, certain genotypes demonstrated differential expression of drought-related genes.

Molecular Genetic Diversity and Combining Ability for Some Physiological and Agronomic Traits in Rice under Well-Watered and Water-Deficit Conditions

Raghda M. Sakran et al.

Summary: This study evaluated diverse rice genotypes and their hybrids under water-deficit and well-watered conditions, and analyzed the genetic traits. The results showed that water deficit reduced rice growth and yield, while increasing leaf rolling and sterility percentage. Both additive and non-additive gene actions were involved in controlling the inheritance of traits, with additive gene action dominating for most traits.

Multivariate Analysis of Morpho-Physiological Traits Reveals Differential Drought Tolerance Potential of Bread Wheat Genotypes at the Seedling Stage

Mohammed Mohi-Ud-Din et al.

Summary: This study assessed the drought tolerance potential of 127 wheat genotypes through PEG-induced drought, revealing significant variations and correlations among different traits. Cluster analysis identified drought-tolerant and drought-sensitive genotypes, with dry weights and tissue water content playing important discriminatory roles in explaining drought tolerance variations. The study concludes that the identified genotypes can serve as valuable genetic tools for improving wheat productivity in arid and semi-arid regions during unpredictable climate change.

Summary: The increasing human population and changing climate have led to frequent drought spells, posing a serious threat to global food security. Identifying high yielding drought tolerant genotypes is an effective approach to combat these challenges. Through a field experiment, it was found that drought stress reduced the growth of wheat genotypes, with BAW 1169 showing the best adaptation and potential for future breeding programs.
