In high-latitude regions, the cold hardiness of buds and canes grapevine is important for budburst time yield in next season. The freezing resistance sampled from six wine grapes currently cultivated Hokkaido, Japan, all them grown autumn to winter, was investigated. A significant difference between cultivars their detected harvested winter. addition, outstanding differences lower temperature e...

Endoreduplication involves a doubling of chromosomal DNA without corresponding cell division. In plants, many cell types transit from the mitotic cycle to the endoreduplication cycle or endocycle, and this transition is often coupled with the initiation of cell expansion and differentiation. Although a number of cell cycle regulators implicated in endocycle onset have been identified, it is sti...

The Arabidopsis thaliana leucine-rich repeat receptor kinase FLAGELLIN SENSING2 (FLS2) is required for the recognition of bacterial flagellin in innate immunity. Recently, FLS2 was proposed to act as a multispecific receptor recognizing unrelated exogenous and endogenous peptide ligands, including CLAVATA3 (CLV3), a key regulator of shoot meristem stem cell production. Here, we report experimen...

A recent report shows that cells in the Arabidopsis apical meristem orientate their cortical microtubules along mechanical stress patterns generated during tissue morphogenesis. This in turn is expected to influence the mechanical properties of the cell via the modification of the cortical microtubule network and the cell wall. This feedback loop controlling the shape of the meristem may act in...
