Fig. 13From: Elucidating the roles of three β-glucuronosyltransferases (GLCATs) acting on arabinogalactan-proteins using a CRISPR-Cas9 multiplexing approach in ArabidopsisIn vitro pollen germination of the glcat mutants and WT. Higher-order glcat mutants showed a significant number of defective pollen as indicated by black arrows. All pictures were taken 3 h after incubation of pollen grains on pollen germination media.
