Molecular and cellular characterization of callus formed from the rice scutellum reveals involvement of an embryo-like developmental program, in contrast to callus formed from the vasculature, which is regulated by genes involved in root organogenesis.

Auxin is a key regulator in vascular cambium development. This study shows that gibberellins promote polar auxin transport along the root, which leads to broadening of high auxin signalling domain in cambium, and thus, to increased xylem formation.

This study revealed a regulatory system in which transcription factor and histone acetylation functions are coordinated for maintaining normal stem vascular cambium development for wood formation in Populus trichocarpa.

Stomatal development is regulated by multiple intrinsic developmental and environmental signals. Here, the authors show that spatially patterned hydrogen peroxide activates the energy sensor SnRK1 to stabilize the SPCH transcription factor and optimize stomatal development in Arabidopsis.

Mitochondrial ascorbate peroxidase (PtomtAPX) is relocated to cell walls undergoing programmed cell death and catalyses lignin polymerization. These results show how xylem cells provide autonomous enzymes needed for lignin polymerization.

Time-lapse imaging of the fern Ceratopteris richardii during meristem initiation and proliferation provides insights into the lineage, identity and division activity of each cell throughout the growth of gametophytes.
