Summary: Adapted management methodologies are required to alleviate increasing and/or more frequent water stress under climate change, enabling successful tree seedling establishment after planting. Hydrogel amendments have been suggested to increase soil water holding capacity, tree seedling growth and survival. However, the effect of a non-uniform addition of hydrogels to tree planting pits as compared to homogenously admixed hydrogels in agricultural soils, as well as effects of hydrogels on woody root system establishment, have been poorly studied.

Summary: This study explores the role of auxin and brassinolide in the changes of root morphology in tobacco under drought stress. It is found that auxin is involved in regulating root diameter and secondary lateral root density, while brassinolide may participate upstream of auxin under drought stress. These findings provide insights into the molecular mechanisms underlying the response of root morphology to drought stress and offer potential targets for breeding drought-tolerant tobacco varieties.

Summary: This study investigates the root morphological, anatomical, and architectural traits and shoot physiological traits of lowland and upland rice under drought conditions in Myanmar. The results show that root traits are reduced under drought in both ecotypes, except for the stele and xylem area. Additionally, the study finds a positive relationship between root traits and agronomic traits in lowland rice, whereas upland rice shows a relationship between root anatomical traits and agronomic traits. Moreover, lowland and upland rice exhibit a negative contribution to biomass by photosynthesis rate, stomatal conductance, and transpiration rate.

Summary: Affected by climate warming, the impact of crop root zone warming on maize seedling growth and nutrient uptake, especially potassium, deserves attention. This study aimed to investigate the effects of root zone warming on potassium absorption and photosynthesis of maize seedlings. The results showed that root zone warming and low potassium treatment significantly affected maize seedling development and photosynthetic characteristics. The interaction between root zone warming and potassium content had a significant influence on maize seedlings. Ensuring the supply of potassium fertilizer under high root zone temperature stress is helpful in alleviating the impact of high temperature stress.

Summary: This study investigated the responses of maize inbred lines with different levels of drought resistance to drought stress and exogenous glycine betaine (GB) treatment. The results showed that drought treatment inhibited growth and development in the drought-sensitive inbred line, while the drought-tolerant inbred line exhibited no significant differences compared to the control. Exogenous GB mitigated the effects of drought stress in both lines. Transcriptome analysis revealed differentially expressed genes (DEGs) in response to drought stress, and the expression patterns of selected DEGs were validated using qRT-PCR. This study provides insights into the potential mechanisms of drought tolerance in maize and the role of exogenous GB in regulating drought tolerance.

Summary: This study aimed to determine the metabolic differences in two rice genotypes, one drought-susceptible (IR64) and one drought-tolerant (Azucena). The results showed that Azucena may evade water stress by increasing the lateral root system growth, while IR64 relies on cell wall thickening to tolerate stress. Significant differences in metabolites were observed in both genotypes, with metabolites related to secondary metabolism, amino acid metabolism, nucleotide acid metabolism, and sugar and sugar alcohol metabolism. Potential metabolic markers for drought tolerance were identified, which can be used for the selection of drought-tolerant rice genotypes.

Summary: Drought stress is a destructive factor for agricultural productivity, but adaptive microbiomes can help to alleviate it. Diverse drought adaptive microbes have been found to assist plants in acquiring nutrients, producing growth regulators, reducing stress ethylene levels, increasing osmolyte concentration, and preventing oxidative damage under water-deficit conditions.

Summary: Combatting the consequences of climate change is crucial for feeding the world's population, with crop simulation models being studied to investigate the impact on agricultural productivity. The use of beneficial microorganisms is an environmentally friendly method of increasing crop yield under environmental stress conditions, showing potential for mitigating climate change effects. More molecular level studies are needed to assess their cumulative influence on plant development in the future.

Summary: This study found that the HR tissue in plants has larger cells and 850 differentially expressed genes compared to PR tissue. AhGLK1 gene plays an important role in post-drought recovery in peanut, and 88 genes related to chlorophyll and photosynthesis are upregulated in HR. The findings provide important insights for exploring candidate gene functions related to drought tolerance and post-drought recovery ability in peanut.

Summary: Roots play a crucial role in water and nutrient acquisition and transport in plants. Different root phenes have varying effects on plant adaptation to low phosphorus and drought stress. Under conditions of low phosphorus and drought stress, bean genotypes with well-developed root systems that grow deep in the soil tend to exhibit better yield performance.

Summary: This study evaluated the differences in yield-related biomass accumulation and transport characteristics among different types of rice, finding that extraheavy-panicle-type rice exhibited significantly higher biomass yield and harvest index than heavy-panicle-type rice and medium-panicle-type rice. Key indicators for breeding extraheavy-panicle-type rice in the future include leaf drooping angle duration and photosynthate transformation rate in the stems after the milking stage.
