The vascular cambium has a remarkable potential to initiate radial thickening of secondary growth to provide biomass, a renewable and sustainable source of bioenergy. This study proposed that INCREASED CAMBIAL ACTIVITY (ICA), a gene encoding a putative pectin methyltransferase, controls cambial activity in Arabidopsis by regulating CK and GA homeostasis and methanol emission.

By using lipidomic profiling analysis with an advance in electrospray ionization tandem mass spectrometry, we identified a large set of phospholipid molecular species (126 species) from Arabidopsis, which revealed the dynamics of phospholipid molecules in seedling growth. Our results provided the insights into the mechanisms of phospholipid molecules regulating plant development.

Phenolamides are compounds with multiple defense roles in plants. We identified three structurally related genes with a similar and/or overlapping activity in phenolamide biosynthesis in rice. Our findings thus illustrate rapid diversification of plant metabolism in response to herbivory and other biotic stresses in nature.

This study demonstrated that wheat's ear play a more important role in carbon (C) assimilation and nitrogen (N) remobilization to grain, than it has been stated before. Our study also validated that ¹⁵N labelling is a useful tool to study N remobilization in wheat.

MARIS plays important roles in Arabidopsis pollen tube and root hair growth

Hong-Ze Liao, Meng-Meng Zhu, Hong-Hui Cui, Xin-Yu Du, Yu Tang, Li-Qun Chen, De Ye, and Xue-Qin Zhang

Mutation in MRI caused rupture in pollen tube and inhibited the growth in root hair. Therefore, MRI is essential for polar growth in Arabidopsis thaliana.
