Gene models: v1.6

Description: Generation of a transcriptome atlas covering most phases in the life cycle of the model bryophyte P. patens, including detailed sporophyte developmental progression (Each experiment has 3 replicates). The processed data from Ortiz-Ramirez et al., 2016 (RMA normalized) were scaled to a median value of 12.

Figure 1. Sporophyte developmental stages

Abb. Developmental stage Description
E1 Embryo 1:
Developing embryo; the upper, chloroplast rich half will develop into the spherical, spore-containing spore capsule, whereas the lower part will connect to the gametophore for nourishment of the developing sporophyte.
E2 Embryo 2:
Elongated embryo without developed stomata. Connection between gametophore and sporophyte still loose but cells started to differentiate.
ES Early sporophyte: Stomata are developed, clear separation of capsule (inflation) and developing seta (2n).
PM Premeiotic sporophyte: Spherical green translucend sporophyte containing spore mother cells (2n), seta starts to turn brownish.
M Meiotic sporophyte: Opaque green sporophyte containing tetrades which will later form each four spores (1n, meiosis occured).
Y Yellow sporophyte: Contains early spores of the final size covered by a plasma membrane, seta darkend during the maturation process.
LB Light brown sporophyte: Spores started to mature, the spore wall thickens by exine deposition.
B Brown sporophyte: Spores are mature, spore wall consists of a thick perine layer with spikes, exine, seperating layer and intine, sporophyte detaches easily.
