The purpose was to comprehensively compare the prediction accuracy of different nitrogen nutrition indexes (NNILAI and NNIDM) derived from critical concentration (Nc) models established by leaf area index (LAI) dry matter (DM) in estimating grain yield indica hybrid rice grown machine-transplanted bowl seedlings. Therefore, field experiments were conducted with two high-yielding varieties five ...

Plants integrate multiple environmental signals to detect and avoid shading from neighbouring vegetation. Two new studies highlight the importance of blue light in the regulation of stem elongation and bending during shade escape.

The spatiotemporal balance between stem cell maintenance, proliferation, and differentiation determines the rate of root growth and is controlled by hormones, including auxin and brassinosteroid (BR). However, the spatial actions of BR and its interactions with auxin remain unclear in roots. Here, we show that oppositely patterned and antagonistic actions of BR and auxin maintain the stem cell ...
