Summary: Dispersal plasticity, which refers to the ability of organisms to adjust their dispersal decisions according to the environment, plays a significant role in ecological and evolutionary dynamics. This study investigates the relationship between dispersal plasticity and fitness sensitivity to environmental gradients in five species of the genus Tetrahymena using microcosm experiments. The results show that dispersal plasticity is generally related to fitness sensitivity, with higher plasticity observed when fitness is more influenced by environmental gradients.

Summary: Bergmann's and Allen's rules have been used to describe ecological patterns across latitudinal gradients, but there is still ongoing discussion about these patterns in tropical montane mammals. This study on the Mountain Treeshrew in Borneo found a complex pattern of morphological variation across elevation, not fully supporting Bergmann's and Allen's rules. It suggests that factors other than temperature may play a more important role in shaping the phenotypic variation of this species.

Summary: Chemical ecology is proposed as a more time-efficient and cost-effective monitoring tool for seagrass ecosystems compared to traditional methods. Analysis of phenolic chemistry in Zostera marina samples revealed correlations with depth, wave exposure, and sample position within a seagrass meadow, with different responses to stress-induced conditions at varying depths. Flavonoids were separated into two groups based on molecular analysis, one group correlated with depth and wave exposure while the other group showed no clear association, possibly due to unexplored factors. The ratio of flavonoids to rosmarinic acid varied between the periphery and center of a seagrass meadow, indicating potential differences in plant stress levels and providing a molecular index for seagrass ecosystem health. More research is required to fully establish the use of phenolic chemistry variation as a monitoring tool for seagrass ecosystems.

Summary: The study combines single-cell transcriptomic, morphological, and electrophysiological characteristics to classify over 1,300 neurons from the mouse motor cortex, revealing extreme diversity in gene expression, morphology, and electrophysiology. While broad families of transcriptomic types exhibit distinct morpho-electric phenotypes, individual transcriptomic types within the same family show a continuum of variability in morphology and electrophysiology without clear boundaries between them, indicating that neuronal types in the neocortex do not always form discrete entities.

Summary: The ability of bacteria to respond to changes in their environment is crucial for their survival. Phenotypic heterogeneity, a remarkable feature of many bacterial responses, enables bacteria to survive fluctuating conditions and implement bet-hedging or division of labor strategies. Recent studies have found that this form of heterogeneity is prevalent in bacterial responses to environmental transitions.

Summary: In arid environments, plants need to optimize water resources due to stochastic rainfall and high evapotranspiration. This study focused on Festuca pallescens, a key native forage species in North Patagonia, where there is a deep rainfall gradient leading to environments with contrasting water availability. The study evaluated the morphological and physiological traits of plants from populations sampled along the rainfall gradient, and found variations in survival, morphological traits, and adaptation to local environments. These results provide insights into the response of non-model species to environments with different water availability in the context of climate change.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
