Juan Losada and María Herrero examined the dynamics of the fertilization process in multiple flowers in the same inflorescence. Depending on the location within the inflorescence, there were differences in the timing and length of stigma receptivity, ensuring reproductive success in varying environmental conditions. Results are published in Scientia Horticulturae.abstract »
A cover story in New Phytologist presents research by recent visiting scientist Rob Baker, Lena Hilman, and Pam Diggle focusing on the evolution of shoot architecture. Using two populations of Mimulus guttatus, they examined the molecular developmental pathways within and among populations, where genetic divergence, adaptation, and speciation occur. abstract »
In new research featured on the cover of Annals of Botany, Juan Losada and María Herrero focused on the secretion of arabinogalactan proteins (AGPs) and the role in the acquisition of stigmatic receptivity in domestic apples. abstract »
Recent visiting scientist and Deland Award Recipient Juan Losada passed his PhD defense from the Aula Dei Experimental Station–CSIC, Spain. His graduate research focused on the events between pollination and fertilization, primarily the role of arabinogalactan proteins in pollen-pistil interactions in Malus and other genera in the Arboretum’s living collection. Congratulations Juan!
Arboretum Visiting Fellow Rob Baker and Pam Diggle published new work in the American Journal of Botany examining the differences in shoot architecture between two populations of Mimulus guttatus. One population has a highly branched perennial lifestyle, while plants from the other population are less branched and annual. They found that shifts in the timing of reproduction play a role in the different patterns of branching. abstract »
To support their research in the living collection, students Juan Losada (Aula Dei Experimental Station–CSIC, Spain), Mariana Oliveira e Castro (University of Coimbra, Portugal), and Preeti Rao (Boston University) were granted Deland Awards for Student Research. more »
