A CRC–MYB chromatin loop controls auxin-mediated nectary growth in Arabidopsis
Abstract Floral nectaries, typically located at stamen bases, secrete sugar-rich nectar containing diverse secondary metabolites. Despite their defined position and specialized function, the mechanisms governing nectary formation remain unclear.
Petal abscission is promoted by jasmonic acid-induced autophagy at Arabidopsis petal bases - Nature Communications
Abstract In angiosperms, the transition from floral-organ maintenance to abscission determines reproductive success and seed dispersion. For petal abscission, cell-fate decisions specifically at the petal-cell base are more important than organ-level senescence or cell death in petals. However, how this transition is regulated remains unclear.
SHI family transcription factors regulate an interspecific barrier - Nature Plants
Abstract Pre-zygotic interspecies incompatibility in angiosperms is an important mechanism to prevent unfavourable hybrids between species. Here we report our identification of STIGMATIC PRIVACY 2 (SPRI2), a transcription factor that has a zinc-finger domain and regulates interspecies barriers in Arabidopsis thaliana, via genome-wide association study.
Plants and agriculture
A chromosome-level Camptotheca acuminata genome assembly provides insights into the evolutionary origin of camptothecin biosynthesis Camptothecin is a monoterpene indole alkaloid with anti-tumor activity. Here, the authors assemble the genome of the camptothecin producing plant Camptotheca acuminata and provide insights into the evolutionary origin of camptothecin biosynthesis by comparing to the vinblastine and vincristine biosynthetic pathway in Catharanthus roseus.
