Hook. ex G. Don. Mani M, Rasangam L, Selvam P, Shekhawat MS Microscopy research and technique Microsc Res Tech Micro-morpho-anatomical mechanisms involve in epiphytic adaptation of micropropagated plants of Vanda tessellata (Roxb.) Hook. ex G. Don. 712-722 10.1002/jemt.23630 Vanda tessellata (Roxb.) Hook. ex G. Don. (grey orchid, family Orchidaceae) is an epiphytic orchid of horticultural importance and currently under threat due to overharvesting and habitat destruction. Micropropagation protocols were developed for the production of grey orchid but the survival success of in vitro regenerated plantlets is uncertain due to lack of understanding about the adaptation mechanism during hardening. The present study describes the structural adaptation mechanism of V. tessellata when the in vitro regenerated plantlets were acclimatized under the greenhouse conditions. Light microscopy has been implicated to identify the adaptational alterations during in vitro to ex vitro transition of micropropagated plantlets. The in vitro induced morpho-anatomical anomalies were more prominently observed in the density of stomata, veins (architecture) and raphides, leaf, and root structural parameters such as water cells and velamen tissues. The results indicated that remarkable reconciliation occurred in structural developments of mechanical and vascular tissues upon epiphytic adaptations of V. tessellata. The study could help in understanding the adaptation mechanism of in vitro regenerated plantlets (especially velamen tissues of epiphytic roots) when transferred to the greenhouse for acclimatization. RESEARCH HIGHLIGHTS: Vanda tessellata is an epiphytic orchid of horticultural importance. Comparative micro-morpho-anatomical analysis at subsequent stages of in vitro regeneration was conducted. Foliar structural and developmental mechanisms towards epiphytic adaptation were studied. In vitro induced structural abnormalities were repaired and epiphytic adaptation was visualized. Stomata, leaf, and root architectures and velamen tissues were well developed in acclimatized plantlets. The report could be useful in the conservation and sustainable utilization of Vanda tessellata. © 2020 Wiley Periodicals LLC.

However, several plants known as mycoheterotrophs exploit fungal partners by reversing the polarity of carbon movement, which usually moves from plant to fungus. We investigated the physiological ecology of a photosynthetic orchid, Apostasia nipponica, which belongs to the first branching group within the Orchidaceae, to improve our understanding of mycoheterotrophic evolution in orchids. The fungal symbionts and nutrition modes of A. nipponica were investigated using molecular barcoding and carbon-13 (13 C) and nitrogen-15 (15 N) measurements, respectively. Community profiling based on a metabarcoding technique revealed that A. nipponica associates with specific Ceratobasidium spp. within ectomycorrhizas-forming clades, whereas isotope analysis revealed that A. nipponica was similar to fully mycoheterotrophic orchids in its 13 C signature and was even more enriched in 15 N than most of the fully mycoheterotrophic orchids that exploit ectomycorrhizal fungi. Our molecular and mass-spectrometric approaches demonstrated, for the first time, that a member of the Apostasioideae, the earliest-diverging lineage of the Orchidaceae, gains carbon through both photosynthesis and fungal cheating (i.e. partial mycoheterotrophy) during the adult stage. © 2020 The Authors New Phytologist © 2020 New Phytologist Foundation.
