Time for another preprint from the lab: www.biorxiv.org/content/10.6... Led by @yuanyuanzhang.bsky.social and @defengshen.bsky.social. We found some surprising secrets that connect and uncouple root barrier formation with systemic nitrogen signaling in shoots. see the thread below for more details

A tunable receptor separates root barrier formation from nutrient signaling through ligand-perception states

In roots, the endodermis controls nutrient entry by forming a barrier known as the Casparian strip. Yet how barrier-associated processes interface with systemic signaling remains unclear. Here, we sho...

PLoS Genet: Whole-genome sequencing reveals a possible molecular basis of sex determination in the dioecious wild yam Dioscorea tokoro (2026) https://www.tsl.ac.uk/publications/166554

PLoS Genet: Whole-genome sequencing reveals a possible molecular basis of sex determination in the dioecious wild yam Dioscorea tokoro (2026)

Dioecious plants, which have distinct male and female individuals, constitute ~5% of angiosperm species and have emerged frequently and independently from hermaphroditic ancestors. Although recent molecular studies of sex determination have started to reveal the diversity of the genetic systems underlying dioecy, research on the evolution of dioecy is limited, especially in monocots. Here, we explore the molecular basis of sex determination in the monocot Dioscorea tokoro, a dioecious wild yam endemic to East Asia. Chromosome-scale and haplotype-resolved genome assemblies and linkage analysis suggested that this plant has a male heterogametic sex-determination (XY) system, with sex-determination regions located on chromosome 3. Sequence comparison between the X- and Y-chromosomes and read coverage analysis revealed X- and Y-specific regions in putative pericentromeric chromosome regions. Within the Y-specific region, we propose two candidate genes that are likely involved in sex determination: BLH9, encoding a homeobox protein, and HSP90, encoding a molecular chaperone. BLH9 functions in a similar way as AtBLH9 in Arabidopsis thaliana. BLH9 could be involved in suppression of female organ development, whereas HSP90 might be required for pollen development. These results shed light on the complex evolution of dioecy in plants.
