How does mixed mating persist, when self-pollination ensures a plant won’t reproduce?
Being a seed from self-pollination guarantees failure in Eucalyptus regnans. Yet despite this, new research shows a mixed-mating system. including selfing, is evolutionarily stable.

Population structure of Betula albosinensis and B. platyphylla
Differences in local abundance and ploidy level are predicted to impact the direction of introgression between species. Hu et al. test these hypotheses on Chinese populations

Now rice has more options to cope with flooding.
When waters rise, should a rice plant shut down and conserve energy till it can breathe again – or should it grow faster to get above the water? New research has produced rice that can do both.

Rhizosphere priming of isogenic wheat lines varying in citrate efflux
Roots don’t simply take up nutrients from the soil. They also exude chemicals. The exudates released from living roots play an important role in plant
