Summary: Citrus plants, specifically tetraploid individuals, exhibit better defense mechanisms against drought stress, resulting in higher activities of antioxidant enzymes and increased accumulation of protective compounds. In contrast, diploid plants suffer from oxidative damage due to increased levels of malondialdehyde and hydrogen peroxide. Moreover, diploids show significant phenotypic differences, such as wilting and rolling of leaves, under water deficit scenarios. Overall, the study suggests that tetraploids have better adaptability and can sustain better under drought conditions.

Summary: The study explores the adaptation characteristics of orange trees under deficit irrigation (DI) strategies over a decade. It found that DI treatments resulted in higher water use efficiencies (WUE) and significant water savings without compromising yield and quality. Despite long-term application of DI regimes, the orange trees were able to adapt and maintain similar yields and quality features to those obtained with full irrigation (FI).

Summary: Water deficit and aluminum toxicity are two major challenges for crop production, particularly in upland acid soils. A study was conducted on rice seedlings to examine the combined effects of these two stresses on antioxidant capacity, protein oxidative modification, proteolytic activity, and proteomic alterations. It was found that the combined stresses resulted in more severe growth reduction, increased protein oxidation, and higher proteolysis compared to individual stresses.

Summary: In this study, the response of citrus plants to waterlogging stress was investigated at the morphological, physiological, and genetic levels. The results showed that waterlogging stress led to reduced SPAD value and root length, as well as increased MDA content and enzyme activities in the roots. RNA-seq analysis revealed differentially expressed genes associated with specific metabolic pathways in the leaves and roots. Overall, this study provides valuable genetic resources for breeding citrus varieties with improved waterlogging tolerance.

Summary: Climate change negatively affects water availability for agriculture, making it crucial to improve water use efficiency under poor irrigation conditions. This study explored the effects of moderate water deficit on tomato plants, including their growth, physiology, yield, quality, and carotenoid biosynthesis gene expression. The findings showed adaptive responses to moderate water deficit, with decreased leaf water potential and growth variables, but increased water use efficiencies. The activities of antioxidant enzymes in leaves and fruits were unaffected by the treatments, and the expression of carotenoid biosynthesis genes was mainly unaffected except for carotene isomerases.

Summary: A comprehensive review of mycoviruses was conducted using databases to explore their molecular features and potential biotechnological applications. The study identified 267 mycovirus species, with 189 recognized by the International Committee on Taxonomy of Viruses. Most mycoviruses had a dsRNA genome, with Botourmiaviridae (ssRNA+) representing 14% of diversity. The Sclerotinicaeae family appeared as the most common host, with 16 viral families identified. Limited knowledge on replication strategy and impact on fungal biology hindered their potential as biotechnological targets.

Summary: In this study, physiological and biochemical studies on salt stress tolerance were conducted on different citrus genotypes at the polyploidy level. It was found that tetraploid trifoliate orange (PO4x) and Cleopatra mandarin (CL4x) showed better photosynthetic and antioxidant capacities under salt stress compared to their respective diploids (PO2x and CL2x). Thus, tetraploidy may enhance salt stress tolerance in citrus.
