The paper investigates the developmental mechanisms behind the unique one-leaf morphology in Monophyllaea glabra by analyzing meristem regulation and gene expression.

This study identifies root morphological plasticity, termed heterorhizy, in the amphibious plant Callitriche palustris in response to submergence, revealing hormonal regulation and evolutionary conservation across species.

This paper develops a live-imaging system to observe the basal region of early Arabidopsis leaf primordia for over 50 hours.

This study investigates the developmental mechanisms of sharp leaf apices in Triadica sebifera, finding that biregional division angles, not cell expansion, drive apex shape and concave joint formation.

The study shows that VEN4 in Arabidopsis and SAMHD1 in humans both participate in DNA repair via homologous recombination, with VEN4 conserving this function despite differences in dNTP metabolism.
