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?

Endosperm development and hybrid seed failure in wild tomatoes
The overall results suggest that near-complete hybrid seed failure can evolve fairly rapidly and without apparent divergence in reproductive phenology/biology.

High-temperature drying increases longevity of rice seed
This study investigates the conditions routinely used by genebanks and finds that standard practice may not be optimal for subsequent seed longevity.
Variations in apomixis in diploid Paspalum rufum
Under self-pollination induction three genotypes of P. rufum develop seeds from both meiotic and aposporous embryo sacs.
Post-shedding seed development in Galanthus and Narcissus
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. study seed characteristics...
Peroxidase allows germination of proanthocyanidin-deficient arabidopsis seeds
A comparison of wild-type Arabidopsis thaliana and PA-deficient mutants finds that peroxidase activity is significantly over-activated in mutant seeds.

Parental environment and seed response to karrikinolide
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...
Windows of opportunity in embryo development
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. 309–319) study the dynamics of embryo and...
