ET2 — Brassica oleracea var. botrytis

Summary

BoET2, also known as GSL8 or CALS10, encodes a callose synthase with callose synthase and transglycosidase activities, placing it in the 1,3-beta-glucan synthase family. In cauliflower, it is associated with cell wall callose deposition, 1,3-beta-glucan anabolism, and response to calcium ions, and localises to the plasmodesma, plasma membrane, Golgi complex and mitochondria. The gene is associated with developmental growth, microsporogenesis and pollen development. Associations with plasmodesmal permeability, symplastic trafficking, auxin transport directionality, plant growth, ploidy level, cytokinesis, cell patterning, shade avoidance, pathogen resistance, stomatal patterning and root development have been observed. Related genes in other species are linked to seedling development, calcium deficiency tolerance, and abnormal pollen development with asymmetric microspore division.
