Explaining seed bank size of an invasive shrub
Bakker et al. find a positive relationship between plant size (V) and seedbank size (S), the SV relationship, using the invasive shrub Ulex europaeus as an

Heterochrony in reproductive development among P. rufum cytotypes
Apomixis in angiosperms is associated with polyploidy and hybridity. In Paspalum rufum, some sexual diploids show apomixis potential. As apomixis seems to derive from a deregulation

The suitability of Brachypodium distachyon for the study of ammonium stress in cereals
Most plants acquire nitrogen from the soil in the form of nitrate (NO3−) or ammonium (NH4+). Ammonium-based nutrition is gaining interest because it helps to

Function of the pleurogram
Water-impermeable seeds have structures (“water gaps” or lens in legumes) for detecting environmental cues that cause them to become water-permeable (nondormant). Physical dormancy is
