Summary: Aquaporins play a crucial role in water transport under stress conditions in plants like Impatiens walleriana, but little was known about this protein family in this species. This study identified and characterized four aquaporins in I. walleriana, showing their expression changes during drought and recovery treatments. Understanding the molecular structure and expression patterns of aquaporins helps expand knowledge on plant water transport mechanisms and drought tolerance strategies.

Summary: This study investigates the physiological roles of aquaporins Aqp1 and Aqp3 in Paramisgurnus dabryanus. The results show that Aqp1 has high abundance in the brain and osmoregulatory tissues, while Aqp3 is mainly expressed in the epithelium of skin and gills. Aqp3 in gills is more responsive to ammonia challenges and significantly increases after 12 hours of air exposure. The changes of Aqp1 and Aqp3 in the intestine are relatively stable after ammonia stress, but Aqp1 increases significantly and Aqp3 decreases after drought stress.

Summary: The complete catalog of transposable elements in the lima bean genome sheds light on the dual domestication events in the Mesoamerican and Andean gene pools. These events make lima bean an ideal model for studying convergent evolution. The mechanisms of adaptation and the genes involved in these processes are not well understood, and this study demonstrates the potential role of transposable elements in shaping gene functions. The analysis of whole-genome sequencing data reveals the genetic structure of lima bean and provides insights into its demographic history and selection processes during domestication.

Summary: This study examines the hydraulic performance of five apple rootstocks under drought stress and finds that leaf water potential and photosynthesis significantly decrease under drought stress. Aquaporins are closely related to the hydraulic conductance of rootstocks under drought stress. The drought resistance of dwarfing rootstocks is associated with the rapid recovery of water-related traits.

Summary: Water dropwort is an aquatic perennial plant rich in protein, dietary fiber, vitamins, and minerals, with its whole-genome sequencing reported for the first time using HiSeq 2000 technology. The establishment of the Water dropwortDB provides resources for further research on O. javanica. Comparative analysis revealed the closest evolutionary relationship between O. javanica and Daucus carota, and the study identified genetic factors related to phenotypic and anatomic differentiation under different water conditions.

Summary: This study investigated the genetic basis of the photosynthetic response of common bean to water deficit, identifying 133 SNP-trait associations related to net CO2 assimilation rate, chlorophyll content, and other key physiological processes. The candidate genes revealed important pathways such as stomatal regulation, protein translocation, and redox mechanisms involved in common bean's response to water-limited conditions. New sources of water-deficit tolerance from different origins were also identified as valuable targets for breeding.

Summary: In this study, DGK genes in common bean were identified and their expression patterns under different developmental stages and salt stress were analyzed. The results showed that PvDGK genes had divergent expression patterns in different tissues and developmental stages, as well as being significantly upregulated under salt stress in root and leaf tissues.

Summary: Common bean is an affordable source to tackle hunger, but its cultivation in water-deficient regions limits plant growth and crop yield. This study evaluates the potential of using a chlorophyte microalga to mitigate the effects of water deficit on two bean cultivars. The application of microalgae increases chlorophyll, sugars, protein, and antioxidant enzymes in the treated plants, leading to improved growth and recovery.

Summary: This study analyzed the transcriptomic changes and phenotypic responses of common bean under single and combined water deficit and fusarium wilt stresses. The susceptible accession showed higher transcriptional changes and more differentially expressed genes in response to combined stresses, while the resistant accession exhibited promising target genes for multiple stress breeding.

Summary: Drought stress has a negative impact on edible vegetable production globally, including economically important crops such as common bean (Phaseolus vulgaris L.) that heavily rely on rainfall or irrigation. This study summarized phenotypic data of 26 Bulgarian common bean mutant lines and cultivars exposed to drought stress, and evaluated the drought stress response using chlorophyll fluorescence and proteomics approaches. Different responses were observed among the mutant lines as several basic photosynthetic parameters were examined. Additionally, a relationship was found between productivity and photosynthetic performance, as well as the expression of key proteins related to stress response. These findings provide support for the selection of drought tolerant common bean lines for sustainable agriculture.

Summary: This study investigated the metabolic regulation of rice roots under different drought conditions. The results showed that drought conditions led to the development of aerenchyma in the roots, increased proline accumulation, upregulated gene expression related to ABA metabolism, suberization, and AQPs activity, and increased deposition of suberin lamella in the root endodermis. In addition, the ratio of unsaturated to saturated fatty acids increased, suggesting an adjustment in cell permeability. However, these metabolic adaptations were not observed under severe drought conditions. Overall, the drought-tolerant mechanism in rice roots is complexly regulated, and ABA metabolism, suberization, and AQPs activity may act as independent or concurrent survival strategies against drought.

Summary: In a genome-wide marker-trait association study, 119 quantitative-trait loci associated with drought resistance were identified in common bean. Three major loci at Pv01 and Pv02 were found to play a significant role in controlling drought resistance. This research provides valuable insights into the genetic basis of drought resistance in common bean.

Summary: This study investigated the effect of abiotic conditions on the endophytic seed microbiome of common bean. The results showed that water withholding and nutrient addition significantly altered the bacterial/archaeal communities structure of the seeds, while there were no statistically supported differences in the fungal microbiome.
