Summary: In this study, we characterized the developmental functions of KAI2 in the grass Brachypodium distachyon. Our results showed that Bdkai2 mutants exhibited abnormal phenotypes in plant development, including increased internode elongation, reduced leaf chlorophyll levels, increased lateral roots, decreased root hair growth, and impaired root colonization by arbuscular-mycorrhizal fungi. Different hormone analogues showed distinct effects on the transcriptome via BdKAI2. Overall, our findings suggest that KAI2 plays multiple important roles in shoot development, root system development, and transcriptional regulation in grasses.

Summary: In monoecious melon, CmLHP1 proteins are found to play a crucial role in regulating plant development, including sex expression, through control of H3K27me3 distribution. Double mutants showed pleiotropic phenotypes and an increase in male:female ratio, associated with deregulation of hormonal response genes.

Summary: Understanding bone homeostasis and regeneration is of great clinical and scientific importance for the development of bone therapy. Macrophages play a crucial role in bone regeneration during healing. In situ hybridization and hybridization chain reaction can be used to explore gene expression in bone tissues.

Summary: Guercio et al. combine structural biology, biochemistry, and plant biology to uncover the dual functions of Pisum KAI2A and KAI2B as both receptors and enzymes with distinct ligand selectivity, highlighting the adaptive sensitivity of KAI2B towards strigolactone phytohormones.

Summary: This study investigates the contribution of wild apple species to the genetic makeup of cultivated apple genomes in Europe and China. The researchers found that wild-to-crop gene flow from two East Asian wild apple species and one European wild apple species played a significant role in the domestication of apple trees. The study also revealed different evolutionary histories between European and Chinese apple varieties.

Summary: This study reveals that Strigolactones (SLs) are the master regulators of transcriptional memory upon drought in Arabidopsis, and this role is partially mediated by the BES1 transcription factor. SLs play a crucial role in achieving the complete after-effect of drought by modulating the transcription patterns of a large subset of genes, especially those related to abscisic acid metabolism and signaling. Promoter-enrichment analysis identified potential cis- and trans-acting factors involved in the SL-dependent and SL-independent regulation of genes during drought and recovery.

Summary: Coevolutionary interactions are a common driver of adaptation, but little is known about the genomic processes underlying coevolution in an ecological context. This article reviews recent advances in coevolutionary theory and genomics, and proposes a practical guide to understanding the dynamics of coevolution using an ecological genomics approach.

Summary: Melon transformation is difficult, but this study optimized the key parameters and achieved significant improvement in transformation efficiency. Ethylene inhibitors and absorbers were found to enhance transformation efficiency of different melon varieties. The optimized protocol was used to generate diploid transgenic melons and edit the eukaryotic translation initiation factor 4E gene using CRISPR/Cas9. This provides a reliable framework for functional gene engineering in melon and holds promise for genetic research and crop improvement.

Summary: We discovered a mechanism in melon where ethylene produced in the carpel is perceived in the stamen primordia through spatially differentially expressed ethylene receptors. The CmEIN3/CmEIL1 ethylene signaling module in stamen primordia activates the expression of CmHB40, a transcription factor that regulates stamen development and organ senescence. Investigation of melon genetic biodiversity revealed an African haplotype associated with bisexual flower development and altered binding of EIN3/EIL1 to the CmHB40 promoter.
