Germline β-1,3-glucan deposits are required for female gametogenesis in Arabidopsis thaliana.

ABSTRACT: Correct regulation of intercellular communication is a fundamental requirement for cell differentiation. In Arabidopsis thaliana, the female germline differentiates from a single somatic ovule cell that becomes encased in β-1,3-glucan, a water insoluble polysaccharide implicated in limiting pathogen invasion, regulating intercellular trafficking in roots, and promoting pollen development. Whether β-1,3-glucan facilitates germline isolation and development has remained contentious, since limited evidence is available to support a functional role. Here, transcriptional profiling of adjoining germline and somatic cells revealed differences in gene expression related to β-1,3-glucan metabolism and signalling through intercellular channels (plasmodesmata). Dominant expression of a β-1,3-glucana
