Kristel Schoonderwoerd and Ned Friedman closely examined the timing and morphology of ovule and seed development in Franklinia alatamaha. They found a very unusual situation. The zygote undergoes dormancy shortly after fertilization until the following growing season. Seed development is completed an entire year after fertilization has occurred. The results are published in the Botanical Journal of the Linnean Society. abstract »
Pollination drops are ovular secretions that form a landing site for pollen in many gymnosperms. Arboretum Putnam Fellow Cary Pirone-Davies and coworkers characterized both the proteins present in the pollination drops and the ovule transcriptome in Cephalotaxus. The results published in Annals of Botany, shed light on the pollination biology of Cephalotaxus. AoBBlog» abstract »
Published in Nature Climate Change (abstract), Elizabeth Wolkovich and Ben Cook examined the phenology of wine grapes and its relationship to climate change. Using 500 years of harvest dates across France, they found that warming due to climate change is linked to much earlier harvest dates. Harvard gazette» NPR»
The Harvard University Center for the Environment is offering summer research assistantships for Harvard Undergraduates. With positions open in both the Friedman Lab and Wolkovich Lab at the Arboretum, students would have the opportunity to study plant responses to climate change. Interested undergraduates should apply via HUCE.
The Australian bee, Amegilla murrayensis, has an unique technique to release pollen from flowers. Rather than shaking the anthers with its mandibles like the American bumblebee, it uses its head. Published in Arthropod-Plant Interactions, Callin Switzer and colleagues compared the pollination behavior of the two bees. abstract »
