Testing macroevolutionary predictions of the Grant‐Stebbins model in the origin of Aeschynanthus acuminatus

New Phytologist, EarlyView.
Summary The Grant‐Stebbins model predicts that a plant species encountering different pollinators across its range may undergo local adaptation and, subsequently, ecological speciation. We tested whether this could explain the origin of Aeschynanthus acuminatus (Gesneriaceae), a species phylogenetically derived from sunbird specialist ancestors.

Improved Longan Genome Assembly Reveals Insights Into Flowering Mechanisms

Plant Biotechnology Journal, EarlyView.
ABSTRACT Longan is an exotic tropical fruit crop and exhibits off‐season flowering induced by potassium chlorate (KClO3), though the molecular mechanisms remain unclear. We assembled a high‐quality, 441.5 Mb genome of variety ‘Shixia’, with a contig N50 at 28.1 Mb, 29, 325 protein‐coding genes, 26 telomeres and 15 centromeres.
