Summary: The activation of hormonal responses plays a crucial role in the drought acclimation ability of plants. In this study, the physiological mechanisms underlying the stress tolerance of house leek (Sempervivum tectorum L.) to water deficit and nutrient deprivation were investigated. Results showed that the accumulation of ABA and jasmonoyl-isoleucine contributed to the activation of effective defense strategies and photoprotection in this CAM plant.

Summary: Monitoring tree physiological responses to drought using drone-based remote sensing and PRI revealed that non-irrigated trees showed higher stress levels compared to irrigated trees. Long-term acclimation influenced the seasonal relationship between PRI and soil water availability. This study demonstrates the importance of remote sensing techniques in scaling tree responses to drought stress and the persistence of legacy effects even after irrigation cessation.

Summary: The overexpression of wild type CrORWT and mutated CrORHis in microalgae significantly increased the accumulation of multiple carotenoids and upregulated the transcription levels of related biosynthetic genes, leading to enhanced tolerance to salt and paraquat stress. Additionally, the endogenous phytohormone abscisic acid (ABA) levels were also elevated in the transgenic cell lines under both normal growth conditions and stress conditions, suggesting a potential role of OR in modulating oxidative stress tolerance.

Summary: Salt stress is a major abiotic stress that limits plant survival and crop productivity. The Salt Tolerance-Related Protein (STRP) has been characterized as a protein involved in plant responses to cold stress and proposed as a mediator of salt stress response in Arabidopsis thaliana. This study investigated the role of STRP in salt stress responses and found that STRP plays a protective role by reducing oxidative stress and is involved in osmotic adjustment mechanisms in A. thaliana.

Summary: This study aimed to explore the efficacy of ABA in surgically induced-CRS type 3 rats. The results showed that ABA significantly shortened the ventricular action potential duration, reduced heart weight, blood pressure, serum creatinine levels, and increased HSP-70 expression.

Summary: Studies have shown that abscisic acid (ABA) protects mice from lipopolysaccharide (LPS)-induced lung injury by activating nuclear factor erythroid 2-related factor 2 (Nrf2) and peroxisome proliferator activated receptor gamma (PPARγ) signaling pathways. Its inhibitory effect on reactive oxygen species (ROS)-mediated endoplasmic reticulum stress may contribute to this protective mechanism.

Summary: The study evaluated the contribution of carotenoids and vitamin C to the antioxidant capacity of citrus fruit pulp, finding that vitamin C had a significant contribution to hydrophilic antioxidant capacity, while the contribution of carotenoids to lipophilic antioxidant capacity varied widely. Valencia Ruby orange had the highest lipophilic antioxidant capacity due to high concentrations of lycopene and phytoene, followed by Nadorcott mandarin with high beta-cryptoxanthin content.

Summary: The study reveals that CBF1 expression is positively associated with cold tolerance in Citrus cultivars, while CBF2 or CBF3 genes did not show a clear relationship with susceptibility to CI. Light avoidance during fruit growth reduces postharvest CI in most sensitive cultivars, which may be linked to the rapid and transient enhancement in the expression of the three CBFs. This indicates that CBFs-dependent pathways mediate cold tolerance responses in sensitive Citrus, with CBF1 playing a role in natural tolerance to CI.

Summary: This study compared red-fleshed oranges with ordinary oranges. The two types of oranges showed similar content and changes in sugars, organic acids, and vitamin C. However, mature Ruby oranges had lower concentrations of sugars, malic and succinic acid, and higher levels of citric acid compared to ordinary Valencia oranges. Additionally, Kirkwood and Ruby oranges exhibited higher lipophilic antioxidant capacity and singlet oxygen absorption capacity than ordinary oranges.

Summary: The nutrient content, bioactive compounds, and antioxidant capacity of red-fleshed orange juices were evaluated and compared with that of standard Navel orange juice. The extraction efficiency of hand and industrial juice squeezing was similar. Red-fleshed orange juices had 3-6 times higher total carotenoids than Navel juices, with phytoene and phytofluene being the main carotenoids. Industrial and treated red-fleshed orange juices had higher tocopherol content but lower vitamin C levels compared to Navel juices. Navel juices showed higher hydrophilic antioxidant capacity, while red-fleshed orange juices showed improved lipophilic antioxidant capacity.

Summary: The study found that tocopherol contents increased during fruit development, but shading reduced gamma-tocopherol accumulation and total content. Cold storage increased total and alpha-tocopherol contents in fruit, but the relationship between tocopherol accumulation and CI tolerance was not clear. Changes in tocopherol synthesis genes during cold storage seemed to be cold-mediated and not related to CI development.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
