Ginkgo DB is a multiscale comprehensive germplasm database for Ginkgo biloba having been developed since 2020. The multi-omic genetic database and occurrence database are two core components of GinkgoDB. Around them, a series of databases like growth monitoring, phenological observation, environment data, as well as photos and articals about ginkgo have been being organized and posted on our site.

GinkgoDB aims at sharing with the world the results of research on the evolutionary ecology of ginkgo and empowering the conservation of wild population of this fascinating species.

This work was supported by National Key Research and Development Program of China (No. 2017YFA0605104) and the National Natural Science Foundation of China (No. 31870190, 32071484).

We started construct quadrats for wild ginkgo populations in 2015. Since 2019, more than 20 permanent quadrat has been constructed. We investigated all the tree, shrub and herb species in the quadrat in detail. What's more, we have been monitoring the temperature and humidity changes in the quadrat with some electronic automatic monitors.

We numbered and recorded the growth condition parameters like DBH, height, crown width, crown condition for trees with DBH greater than 1cm. For trees with DBH greater than 5cm, we made metal bands (dendrometers) so that we can record their growth rate.

The ginkgo trees in those quadrats are the focus of our study. We collected specimens, seeds, molecular samples and other biological samples of those ginkgo trees. And their functional traits have been measured. Further more, We collected some soil samples near their root for research.

To protect the wild ginkgo germplasm resources, more quadrats will be constructed in the future.

We study evolutionary ecology of relict tree species using the living fossil Ginkgo biloba (maidenhair tree) as major study systems by integrating field observatory and monitoring data, multi-omic data and experimental data. The key question We have been focused on is the evolutionary causes and genetic bases underlying regulation mechanisms of population size and distribution with an emphasis on three key ecological processes, i.e., reproduction, morality and dispersal. The specific questions include response strategies to global climate change and adaptive evolution, sex chromosome evolution and sexual dimorphism, evolution of secondary metabolites, plant-microbial coupling and coevolution.
