The decision to germinate is regulated by divergent molecular networks in spores and seeds

Abstract: Summary Dispersal is a key step in land plant life cycles, usually via formation of spores or seeds. Regulation of spore‐ or seed‐germination allows control over the timing of transition from one generation to the next, enabling plant dispersal. A combination of environmental and genetic factors determines when seed germination occurs. Endogenous hormones mediate this decision in response to the environment. Less is known about how spore germination is controlled in earlier‐evolving nonseed plants.Here, we pre… Show more

“…Several pieces of evidence suggest that ABAmediated stomatal closure reported in the moss species P. patens is not analogous to that observed in seed plants. The first is that P. patens does not exhibit the guard cell-specific expression of an SnRK2 (22,25), which is required for a stomatal response to ABA (SI Appendix, Fig. S6) (26).…”

“…Reconstructed evolution of the interactions between A CE /GA (yellow), ABA (red), SnRK2s (green), and S-type anion channels (blue). Precursors of GA and ABA interact to modulate spore dormancy in mosses (22). It is not yet known whether an SnRK2 is involved in this process (dotted green line), or indeed whether these hormones and signaling pathways influence phenotypes in the most basal extant vascular plant lineage, the lycophytes (dotted lines).…”

“…One or more of these requirements for ABA-driven stomatal responses does not occur in nonseed plants. In lycophytes and ferns, native SnRK2s are unable to activate native SLACs , while a functional SnRK2-SLAC pairing, albeit weak, observed in P. patens (Lind et al, 2015) is not specific to the guard cells Vesty et al, 2016) and likely plays a role in nitrate homeostasis. In well-studied angiosperms there is a potent pairing of native SnRK2s and SLACs that are specifically expressed in guard cells (Li and Assmann, 1996;Geiger et al, 2009;Fujii et al, 2011).…”
