Fig. 6. BRI1-BRL gene family evolution.

Fig. 6

a. Phylogenetic tree of the BRI1-BRL gene family in vascular plants. The EMS1 gene family, which is the sister group of BRI1-BRL, was employed as the outgroup. Bootstrap values are labeled along with clades. Boxes are used to show the domain configurations of each gene. Apu, Anthoceros punctatus; Ita, Isoetes taiwanensis; Adc, Adiantum capillus-veneris; Gbi, Ginkgo biloba; Ath, Arabidopsis thaliana. LRR, leucine-rich repeat domain.

b. The conserved sites for the BRI1-BRL gene family. The conserved sites were indicated with red boxes.

c. Expression of A. capillus-veneris BRI1-BRL and EMS1 genes in samples from various organs and tissues, including stem (SA, shoot apex), leaf stalk (SFL, stalk of the fist leaf; SCL, stalk of circinate leaf; SUL, stalk of unfurled leaf), frond (FL, first leaf; CL, circinate leaf; UL, unfurled leaf; JSEL, juvenile-sporangium-excised leaf; GSEL, green-sporangium-excised leaf; MSEL, mature-sporangium-excised leaf; DSEL, dehiscent-sporangium-excised leaf), sporangium (JS, juvenile sporangium; GS, green sporangium; MS, mature sporangium) and gametophyte (EG, embryo gametophyte; YS, young sporophyte).
