Dataset Information

The gravistimulation-induced very slow Ca²⁺ increase in Arabidopsis seedlings requires MCA1, a Ca²⁺-permeable mechanosensitive channel.

ABSTRACT: Gravity is a critical environmental factor affecting the morphology and function of plants on Earth. Gravistimulation triggered by changes in the gravity vector induces an increase in the cytoplasmic free calcium ion concentration ([Ca²⁺]_c) as an early process of gravity sensing; however, its role and molecular mechanism are still unclear. When seedlings of Arabidopsis thaliana expressing apoaequorin were rotated from the upright position to the upside-down position, a biphasic [Ca²⁺]_c-increase composed of a fast-transient [Ca²⁺]_c-increase followed by a slow [Ca²⁺]_c-increase was observed. We find here a novel type [Ca²⁺]_c-increase, designated a very slow [Ca²⁺]_c
