When it comes to attracting pollinators, Saururus chinensis is a bit of a chameleon. By turning some of its leaves white, it can attract more visitors. But why don't the leaves stay white?
The overall results suggest that near-complete hybrid seed failure can evolve fairly rapidly and without apparent divergence in reproductive phenology/biology.
Seeds of the moist temperate woodland species Galanthus nivalis and Narcissus pseudonarcissus, which disperse during spring or early summer, germinate poorly in laboratory tests. Newton et al.Β study seed characteristics...
A comparison of wild-type Arabidopsis thaliana and PA-deficient mutants finds that peroxidase activity is significantly over-activated in mutant seeds.
Seeds from different populations of the same species often show distinct germination responses to the smoke-derived chemical karrikinolide (KAR1), thus limiting its potential for use in weed management. Gorecki et al...
Variation in mature seed size is the result of a complex array of interactions involving genes, genomes and environment that may change during development. Diggle et al. (pp. 309β319) study the dynamics of embryo and...
