Arabidopsis thaliana B-GATA factors repress starch synthesis and gravitropic growth responses.

The New phytologist - 1 Aug 2023

Sala Jan, Mosesso Niccolò, Isono Erika, Schwechheimer Claus

Abstract excerpt

Plants perceive the direction of gravity during skotomorphogenic growth, and of gravity and light during photomorphogenic growth. Gravity perception occurs through the sedimentation of starch granules in shoot endodermal and root columella cells. In this study, we demonstrate that the Arabidopsis thaliana GATA factors GNC (GATA, NITRATE-INDUCIBLE, CARBON METABOLISM-INVOLVED) and GNL/CGA1...
