“…Gastrodia is the most species-rich genus among mycoheterotrophic plants, which obtain carbon from their associated fungi without photosynthesis. Numerous recent studies have re-examined the diversity of Gastrodia species in various Asian countries (e.g., Hsu and Kuo, 2010;Suetsugu, 2013Suetsugu, , 2014Suetsugu, , 2016aSuetsugu, , 2016bHuang et al, 2015;Hsu et al, 2016;Tsukaya and Hidayat, 2016;Suetsugu et al, 2018aSuetsugu et al, , 2018bMa et al, 2019), and, as a result, the genus has been updated to include approximately 100 accepted species. Therefore, it is a crucial taxon to identify species diversification in mycoheterotrophic plants.…”

Gastrodia is the most species-rich genus among mycoheterotrophic plants, and is thus an essential taxon to understand the mechanism of species diversification in mycoheterotrophs. In this study, we developed microsatellite markers with high transferability for four Gastrodia species to examine genetic differentiation and similarity among species, populations and individuals. The 12 microsatellite markers developed from a G. fontinalis library showed high transferability for the ramets that identified G. nipponica, G. kuroshimensis and G. takeshimensis. In addition to the high transferability of these markers, we observed low allele variation within a sampled population of each species and allele differences among the four species. The 12 markers described here will be useful for investigating the genetic differences among and within the Gastrodia species, which evolved by a limitation of gene flow.

“…Commonly, selfing is considered to decrease genetic variation and increased genetic drift, high levels of inbreeding depression (Culley & Klooster, 2007). However, when pollinators are rare or absent, cleistogamous selfing can exhibit fitness advantages distinct from out-crossing, owing to the increase of seed production, less energetical cost, and inherent automatic selfing advantage (Culley & Klooster, 2007;Suetsugu, 2014Suetsugu, , 2016Waller, 1984). Outcrossing in the orchid may gradually lose its position under pollinators scarcity and extreme water-deficit conditions.…”

Dendrobium wangliangii is an epiphytic orchid distributed in the Jinshajiang dry‐hot valley in Luquan County, Yunnan Province, China. Most Dendrobium spp. typically have a low fruit set, but this orchid shows a higher fruit set under natural conditions despite the lack of effective pollinators. The pollination biology of the critically endangered D. wangliangii was investigated in this study. A fruit set rate of 33.33 ± 4.71% was observed after bagging treatment in 2017 and a high fruit set rate (65.72 ± 4.44% in 2011; 50.79 ± 5.44% in 2017) was observed under natural conditions, indicating that D. wangliangii is characterized by spontaneous self‐pollination. The anther cap blocked the growing pollinium; thus, the pollinium slid down and reached the stigmatic cavity, leading to autogamous self‐pollination. Specifically, 51.50% of 162 unopened flowers (total 257 flowers) of this Dendrobium species under extreme water‐deficit conditions developed into fruits, suggesting the presence of cleistogamy in D. wangliangii. Here, cleistogamy may represent the primary mode of pollination for this orchid. Spontaneous self‐pollination and specific cleistogamous autogamy could represent major adaptions to the drought and pollinator‐scarce habitat in the Jinshajiang dry‐hot valley.

The Orchidaceae are the largest and most diverse family of flowering plants on earth, and include some of the most important horticultural plants. While mycoheterotrophic orchids belonging to the genus Gastrodia are known to be provided with carbon through mycorrhizal fungi, the relationship between the plants and fungi is poorly understood. Furthermore, it is challenging to cultivate Gastrodia spp. in vitro. In this study, we present an efficient method for germinating Gastrodia pubilabiata (Gp), Gastrodia nipponica (Gn), and Gastrodia confusa (Gc) plants in vitro, which results in the production of a protocorm and tuber, as under natural conditions. The Gp and Gc plants produced flowers 126 and 124 days after germination, respectively, and set seed under our artificial conditions. In addition, Gp plants flowered up to three times a year from a single tuber. Using our artificial cultivation system, we identified some of the mycorrhizal fungi associated with these plants. Gastrodia spp. appear to obtain carbon from many kinds of mycorrhizal fungi. Our artificial cultivation method is a rapid and efficient means of growing Gastrodia spp. In addition to having applications in research and commercial nurseries, this method could be used to conserve Gastrodia spp. in ex situ, many of which are endangered.
