Summary: Understanding the coordination and variance of plant traits across climatic gradients is crucial for assessing their adaptive potential to climate change. A study on European beech in the French Alps revealed that populations growing under drier and warmer conditions presented wide variance for xylem anatomical and hydraulic traits, while colder locations showed decreased water transport capacity. The study also emphasized the importance of intrapopulation trait variance and trait network analysis in understanding species adaptation and acclimation potential to a shifting environment.

Summary: The understanding of the molecular basis of abiotic stresses, such as salt, cold, and drought, is crucial for developing breeding and genetic engineering strategies in sugarcane. This study investigated the plant's responses to these stresses, including chlorosis, wilting, leaf rolling, and changes in water content. The results also showed an accumulation of LPO and an increase in proline content, indicating the plant's stress responses. Additionally, differential gene expression analysis revealed the involvement of various stress-responsive genes in sugarcane seedlings, providing insights into the molecular basis of stress response in this important crop.

Summary: In breeding new sugarcane varieties, the traditional statistical methods may not be suitable due to the non-normal or non-linear distribution of the survey data. The projection pursuit clustering (PPC) model provides a promising approach as it can analyze high-dimensional, non-linear, and non-normal data without making assumptions. In this study, the PPC model was successfully used to evaluate sugarcane varieties and identify excellent resources for further breeding.

Summary: Drought stress has negative impacts on crop growth and profitability. This study compared two different alfalfa subspecies and identified key morphological and physiological traits for enhancing biomass yield under drought stress. Field surveys and root architecture analysis further validated the importance of these traits. Different drought-adaptive strategies were identified across subspecies populations, which will contribute to the development of alfalfa cultivars suitable for various growing conditions. Combining genes from both subspecies can lead to the development of drought-tolerant alfalfa with higher productivity under limited water availability.

Summary: This study investigated the effects of chronic intermittent cold stress on body weight, food intake, working memory, and anxiety disorders in rats. The results showed that male rats exposed to cold stress had an increase in adrenal glands weight, while females exhibited decreased food intake. Furthermore, gender played a significant role in the response to chronic stress on behavior.

Summary: Water stress, either in the form of drought or flood, is a major limiting factor for sugarcane growth and yield. Different water regime conditions affect photosynthetic potential and stomatal conductance in sugarcane cultivars, while a combination of drought and flood reduces fresh stem weight. Auxin application rates impact the number and fresh weight of adventitious roots in sugarcane, with higher fresh stem weight observed in the K93-219 cultivar.

Summary: Cold stress is a major constraint for plant growth and development. The application of melatonin, a critical bio-stimulant, has been found to improve plant performance under cold stress by maintaining membrane integrity, water uptake, photosynthetic efficiency, and antioxidant activities.

Summary: The overexpression of SoTUA gene in sugarcane enhances protein expression, cold resistance, growth, and yield. Transgenic plants have higher levels of soluble protein and sugar, lower levels of malondialdehyde, and increased expression of cold-defense genes compared to wild type. This positive effect of SoTUA protein on chilling stress protection is consistent across transgenic plant generations.

Summary: The study evaluates popcorn inbred lines with differing water use efficiency under two water regimes in a greenhouse. Water use efficient inbred lines showed superior performance in root traits, CO2 assimilation rate, and exhibited high heterosis estimates for various characteristics. The study indicates the importance of root physiological and morphological traits in explaining water use efficiency and the potential for genetic gains through heterosis in hybrids.

Summary: Brazilian sugarcane cultivars RB867515, RB928064, and RB935744 exhibited different responses to Al-induced stress. RB867515 was the most Al-tolerant cultivar, showing no decline in nutrient content, photosynthesis, transpiration, and stomatal conductance after Al exposure; it also had the highest Al content in the roots and important MDH and SOD gene expression. RB928064 showed low expression of SOD in roots and leaves, while RB935744 showed important expression of the SOD gene only in the leaves. Sugarcane cultivars were classified in descending Al-tolerance order as RB867515 > RB928064 = RB935744.

Summary: In this study, a high sucrose content sugarcane mutant clone, GXB9, was compared to the low sucrose mother clone B9 on morphological, agronomical, and physiological levels. The results showed significant differences between GXB9 and B9 in terms of growth traits, physiological parameters, and cane quality. GXB9 exhibited lower performance in most traits compared to B9, except for higher net photosynthetic rate, stomatal conductance, and transpiration rate. This suggests that GXB9 is an elite source for future breeding due to its high sugar content and better overall performance compared to B9.

Summary: This study investigated the root morphological traits and changes in phytohormones of allelopathic and non-allelopathic rice cultivars when co-planted with herbicide-resistant barnyard grass. The results showed that the allelopathic rice had greater shoot and root biomass and exhibited better root morphology compared to other rice cultivars. Additionally, the allelopathic rice responded positively to the stress of herbicide-resistant barnyard grass, with changes in phytohormonal content.

Summary: The study revealed that water stress can increase organic acid exudation from sugarcane roots and alter microbial gene expression. Under water stress conditions, genes associated with certain microbial genera showed decreased expression, while others related to specific functions exhibited increased expression.
