Use of low temperatures to preserve pollen of species that cannot be preserved under conventional seed bank conditions by Anna Nebot

I obtained my conservation biology degree at the University of Valencia (Spain) in 2012. After that I conducted a stage at the Biodiversity Conservation Centre (CCB) of Sardinia (Italy) and in 2017 I got my PhD in Botany at the University of Cagliari. At the beginning of my career I specialized on reproductive biology studies of endemic and threatened Mediterranean plant species. In 2017, as a postdoc, and under the supervision of Hugh Pritchard and Daniel Ballesteros, I worked on desiccation tolerance and long-term pollen preservation of several wild species. And after that I investigated about the optimum medium to test the viability of fresh and stored pollen of several Cycad species that were preserved at Nong Nooch Botanical Garden in Thailand. Nowadays I am a researcher at the Botanical Garden of the University of Valencia.

Ensuring that seed and pollen samples that come to NLGRP are alive – and stay alive – is one of NLGRP’s top priorities. I manage the labs that perform viability testing on seeds in the United States national collection, as well as on research material like seeds, pollen, and fern spores, which are used to improve storage methods and aging detection. Some of our biggest challenges come from wild plant species, many of which are rare or endangered. I work with diversity: in plant material, researchers, seed analysts, data managers and new technologies, all geared towards keeping the collection alive and healthy.
