Also known as: SHOOT GRAVITROPISM 2; T8E3.1; T8E3_1
Summary: encodes a novel protein that may be part of a gene family represented by bovine phosphatidic acid-preferring phospholipase A1 (PA-PLA1)containing a putative transmembrane domain. SGR2 is involved in the formation and function of the vacuole.
