Keywords temperature water stress COP1 HY5 SnRK2s root development thermomorphogenesis Arabidopsis trichoblast drought Results and discussion To investigate the interaction between temperature and water stress on root growth, we grew wild-type (Col-0) Arabidopsis seedlings in soil with a range of soil water contents (13%–23%), at either 20°C or 28°C. We found that roots and shoots respond differently to combined temperature and water stress treatments (Figures 1A and S1A).

Abstract Accurately determining the elemental composition of plant tissues is essential for physiological studies on plant stress, including salinity tolerance. However, high-throughput routine analysis of light elements (range of sodium to calcium) in plant samples is challenging due to the need for complete sample dissolution and expensive inductively coupled plasma-mass-spectrometry (ICP-MS) analysis.

Abstract Warm temperatures have a dramatic effect on plant development. In shoots, stems elongate, and leaves are raised in a developmental programme called thermomorphogenesis. This results in enhanced leaf cooling capacity. Thermomorphogenesis is tightly intertwined with light signalling pathways.
