“…The well-known relic Ginkgo biloba is one of the oldest living seed plants, and its natural habitat is restricted to small areas of China (Shen et al, 2005;Gong et al, 2008;Tang et al, 2012). Because of its edible seeds, medicinal efficacy, and ornamental value, this species is now widely cultivated worldwide.…”

ABSTRACT. Ginkgo biloba is considered to be a living fossil that can be used to understand the ancient evolutionary history of gymnosperms, but little attention has been given to the study of its population genetics, molecular phylogeography, and genetic resources assessment. Chloroplast simple sequence repeat (cpSSR) markers are powerful tools for genetic studies of plants. In this study, a total of 30 perfect cpSSRs of Ginkgo were identified and characterized, including di-, tri, tetra-, penta-, and hexanucleotide repeats. Fifteen of 21 designed primer pairs were successfully amplified to yield specific polymerase chain reaction products from 16 Ginkgo cultivars. Polymorphic cpSSRs were further applied to determine the genetic variation of 116 individuals in 5 populations of G. biloba. The results showed that 24 and 76% genetic variation existed within and among populations of this species, respectively. These polymorphic and monomorphic cpSSR markers can be used to trace the origin and evolutionary history of Ginkgo.

“…To explore the plant communities and habitat similarity among four regions, we draw the floristic similarity dendrogram according to Tang et al (2011Tang et al ( , 2012 using the PaST software (Hammer et al, 2001). The values of relative DBH for long-lived individuals of Ginkgo biloba and Taxus chinensis were applied in the similarity dendrogram analysis using Euclidean and group average clustering.…”

“…Nowadays in Fanjingshan Mountain and its nearby regions, some wild individual or even wild populations of relict species can still be found (Axelrod et al, 1996;Tang et al, 2011Tang et al, , 2012, including Davidia involucrata Baill., Ginkgo biloba L., Liriodendron chinense (Hemsl.)

Distribution patterns of long-liveD inDiviDuals of relict plants arounD fanjingshan Mountain in china: iMplications for in situ conservation.-The mountain areas in south-central China are widely recognized as refugia of relict plants during the late Neogene and Quaternary periods. In this paper, we try to explore the distribution patterns of natural habitats and to exactly locate the refugia of relict species around Fanjingshan Mountain using dendrological data of long-lived individuals (≥100 years old). Six typical relict plants were found around the mountain, i.e. Cyclocarya paliurus, Ginkgo biloba, Liriodendron chinense, Pinus massoniana, Podocarpus macrophyllus, and Taxus chinensis. The long-lived individuals were divided into three classes according to their ages: Class-I (≥500 years), Class-II (300-499 years), and Class-III (100-299 years). Our results showed that the south-west region to the mountain was the main distribution area of Class-I trees of G. biloba and T. chinensis, most of which occurring in the same small village (Yangliu Village of Yinjiang County). The north-east region harboured all the six relict species. Floristic analyses also indicated these two regions were very similar in tree growth as measured by DBH (diameter at breast height of 1.3 m). Thus, these two areas would have provided long-term suitable habitats for relict species. The south-west region, especially the small village Yangliu, should be given highest priority for in situ conservation of relict species and other rare and endangered plants. Attention should also be paid to the north-east region for its very high species diversity of relict species.Key words: biodiversity; endemic plants; fengshui forests; glacial refugia; old trees.

En el presente trabajo se intentan explorar los patrones de distribución de los hábitats naturales y la localización exacta de los refugios para especies vegetales relictas en los alrededores de la montaña Fanjinshan, mediante el empleo de datos dendrológicos de individuos longevos (≥100 años). En el área de estudio se encontraron seis especies vegetales típicamente relictas: Cyclocarya paliurus, Ginkgo biloba, Liriodendron chinense, Pinus massoniana, Podocarpus macrophyllus y Taxus chinensis. Los individuos longevos se dividieron en tres categorías de acuerdo con su edad estimada: individuos de Clase I (≥500 años), de Clase II (300-499 años) y de Clase III (100-299 años). Nuestros resultados muestran que la región situada al suroeste de la montaña se corresponde con la principal área de distribución de los árboles de Clase I de G. biloba y T. chinensis, localizándose la mayor parte de éstos en los alrededores de una pequeña aldea (Yang...

“…Thus, understanding the origin and phylogeography of G. biloba will help to elucidate the evolutionary history of seed plants, and the climate and geological changes that have occurred over time in the Northern Hemisphere. Its natural habitat is restricted to small areas of China (Shen et al, 2005;Gong et al, 2008;Tang et al, 2012), but this species is now widely cultivated around the world due to its edible seeds, medicinal properties, and ornamental value. Despite considerable field surveys and extensive fossil records for the genus Ginkgo (Zhou and Zheng, 2003;Zhou, 2009;Zhou et al, 2012), little is known about population genetics, molecular ecology, and genetic resources of this species.…”

Evidence for the persistence of wild Ginkgo biloba (Ginkgoaceae) populations in the Dalou Mountains, southwestern China

Abstract: The corroborative evidence confirms the finding that these populations represent fragments of the original natural Ginkgo in the valley and lower mountain slopes of the Dalou Mountains.
