Expanding the reach of the bionic leaf

Postdoctoral fellow Kelsey Sakimoto

Scientists estimate that food supplies will need to double by 2050 to meet demand. In greenhouse experiments conducted at the Arnold Arboretum, Harvard researchers discovered a way to more than double crop size by introducing a soil bacterium that converts nitrogen from the atmosphere into robust and sustainable fertilizer.

The future of wine grapes

Elizabeth Wolkovich

Most wine is produced from the same 12 varieties of grapes. Agricultural crops, including wine grapes, are predicted to be greatly impacted by climate change. Published in Nature Climate Change, Elizabeth Wolkovich, Ignacio Morales-Castilla and co-workers discuss how the other ~1100 varieties of grapes available, and the diversity of their attributes, may play an important role in the future.

Reproductive development in pawpaw

Juan Losada
While the pawpaw, (Asimina triloba) is one of few native North American fruit trees, not much is known about its flower and fruit development. Juan Losada (Arboretum Fellow), Iñaki Hormaza and Jorge Lora (Jewett Prize Recipient) examined its development in American Journal of Botany. Complementing this work, the genome of Asimina triloba, 12708*A, is being sequenced with support from an Arboretum Sequencing Award. abstract»

Tall trees and sugar transport

Jessica Savage

New research in Nature Plants by Jessica Savage, Juan Losada, and Missy Holbrook finally answers the long standing question of how trees maintain efficient sugar transport as they grow taller. They found that the phloem structure, the vascular tissue that transports carbohydrates, changes with increasing height. abstract» Harvard Gazette »

Reconstructing the ancestral flower

Kristel Schoonderwoerd

The early evolution of flowers remains something of a mystery. As part of her Master’s research, Kristel Schoonderwoerd, PhD Candidate in the Friedman Lab, joined a large international team to reconstruct the ancestral flower based on DNA and floral characteristics of known flowers. The results are published in Nature Communications. more» abstract»
