Summary: The study introduces a new mutant allele of the UVR8 gene, uvr8-17D, which results in weak constitutive photomorphogenesis and extreme UV-B responsiveness when overexpressed in plants. The UVR8(G101S) mutant, predominantly monomeric in vivo and inefficiently inactivated after UV-B activation, provides further insight into the mechanisms of UVR8 activation and inactivation. Additionally, the combination of G101S and W285A mutations in UVR8 leads to robust constitutive photomorphogenesis in plants.

Summary: Endoreduplication, a common process in plants, is related to plastic responses to stress factors. This study investigated the level of endoreduplication in Ceratodon mosses and found higher endoreduplication index in the haploid cytotypes. The haploid cytotypes exhibited higher endoreduplication index during hot and dry periods, while the diploid cytotype showed no seasonal difference.

Summary: Plants face stressful environmental conditions and may be simultaneously exposed to different stress factors like UV radiation and cold, leading to unique and unpredictable interactions on stress-related genes and flavonoid biosynthesis pathways. The presence of UV radiation can abolish correlations between gene expression levels of flavonoid biosynthesis and flavonol levels, while cold-regulated genes may still play a role in plant responses under combined stress.

Summary: This study investigates the impact of UV-B radiation on plant fitness and gene expression. The results show that the UV-B photoreceptor UVR8 plays an important role in plant acclimation and tolerance to UV-B stress. Additionally, the study identifies other genes and pathways involved in oxidative stress, photoprotection, and DNA damage repair in response to UV-B radiation. These findings highlight the functional importance of UVR8-mediated response in plants.

Summary: In this study, 23 VcBBX genes were identified in blueberry, and 11 of them responded to UV-B radiation, acting as bridges between UV-B and phytohormone signaling pathways according to RNA-seq data. Most of the VcBBX genes showed responses to drought, salt, and cold stress. VcBBX24, highly expressed in all organs, not only responded to abiotic stress, but also interacted with proteins in UV-B and phytohormone signaling pathways, suggesting its important role in integrating abiotic stress and phytohormone signaling networks.

Summary: Serotonin and melatonin are master regulators of plant growth and development, and their biosynthesis genes show distinct evolutionary relationships among different plant species. The expression of these genes is influenced by tissue-specific, developmental, and stress/hormone-mediated variations, with light/dark cycles also affecting their expression. MiRNAs regulate the expression of genes involved in serotonin and melatonin biosynthesis under light and stress conditions, providing opportunities for functional characterization of target genes in plant physiology.

Summary: Sunlight, specifically UV-B wavelength, plays a crucial role in regulating gene expression and genome integrity in plant development. Through cytogenetic and deep-learning-based analyses, researchers have identified the location of UV-B-induced photoproducts and quantified the impact of UV-B irradiation on constitutive heterochromatin content in different Arabidopsis natural variants. They also discovered that UV-B exposure promotes constitutive heterochromatin dynamics, which varies among Arabidopsis ecotypes with divergent heterochromatin contents. Additionally, the study found that the restoration of chromocenter shape relies on the UV-B photoreceptor, UVR8. These findings provide valuable insights into the modulation of constitutive heterochromatin content in Arabidopsis thaliana in response to UV-B exposure and perception.

Summary: The expression of miR408 is strongly repressed by salt stress in maize. Overexpression of MIR408b enhances salt sensitivity in maize by influencing sodium efflux, lignin accumulation, and vascular bundle development. Additionally, miR408 negatively regulates salt tolerance by affecting the expression of cell wall biogenesis genes under salt conditions.

Summary: This meta-analysis investigates the transcript dynamics of NLR genes in Arabidopsis thaliana under various biotic and abiotic stresses, revealing that most NLR genes are induced by pathogens, immune elicitors, or salicylic acid, while some are repressed by abscisic acid, high temperature, and drought. The study also highlights the dependency of pathogen-induced expression of certain NLR genes on salicylic acid.

Summary: The study characterized OsRR6, a type-A response regulator in rice, which plays a crucial role in plant response to abiotic stress, promoting tolerance to drought and salinity. OsRR6 expression is regulated by exogenous cytokinin and various abiotic stress treatments, affecting root growth, anthocyanin accumulation and cytokinin sensitivity in plants. OsRR6(OX) plants showed upregulated defense response and anthocyanin metabolism genes, indicating a positive role of OsRR6 in imparting abiotic stress tolerance.

Summary: Modelling suggests that the Montreal Protocol is helping to mitigate climate change by protecting the land carbon sink and the ozone layer, as well as by reducing greenhouse gas emissions. This is achieved through control of ozone-depleting substances, which has led to the recovery of the ozone layer and avoided harmful increases in ultraviolet radiation. Additionally, the Protocol has co-benefits for plants and their capacity to store carbon, which has not been investigated previously.

Summary: This study finds that different species of Sphagnum moss have varied physiological and molecular responses to desiccation, which are not directly correlated with their position in relation to the water table. Increased expression of drought responsive genes is accompanied by an increase in abscisic acid (ABA) levels, supporting its role in desiccation responses in Sphagnum.

Summary: Metabarcoding has shown promise as a cost-effective method for studying insect communities, but its performance varies among studies. This research evaluated the impact of DNA extraction protocols on metabarcoding results using mock community experiments. The results showed that a nondestructive, mild lysis approach is best for reconstructing species lists and approximate counts, while homogenization protocols are better for characterizing biomass composition. Species-specific reference data and adequate spike-in data were also important for accurate species abundance estimates.
