Comparative Transcriptome Analysis Suggests Convergent Evolution Of
Alejo-Jacuinde et al. BMC Plant Biology (2020) 20:468 https://doi.org/10.1186/s12870-020-02638-3 RESEARCH ARTICLE Open Access Comparative transcriptome analysis suggests convergent evolution of desiccation tolerance in Selaginella species Gerardo Alejo-Jacuinde1,2, Sandra Isabel González-Morales3, Araceli Oropeza-Aburto1, June Simpson2 and Luis Herrera-Estrella1,4* Abstract Background: Desiccation tolerant Selaginella species evolved to survive extreme environmental conditions. Studies to determine the mechanisms involved in the acquisition of desiccation tolerance (DT) have focused on only a few Selaginella species. Due to the large diversity in morphology and the wide range of responses to desiccation within the genus, the understanding of the molecular basis of DT in Selaginella species is still limited. Results: Here we present a reference transcriptome for the desiccation tolerant species S. sellowii and the desiccation sensitive species S. denticulata. The analysis also included transcriptome data for the well-studied S. lepidophylla (desiccation tolerant), in order to identify DT mechanisms that are independent of morphological adaptations. We used a comparative approach to discriminate between DT responses and the common water loss response in Selaginella species. Predicted proteomes show strong homology, but most of the desiccation responsive genes differ between species. Despite such differences, functional analysis revealed that tolerant species with different morphologies employ similar mechanisms to survive desiccation. Significant functions involved in DT and shared by both tolerant species included induction of antioxidant systems, amino acid and secondary metabolism, whereas species-specific responses included cell wall modification and carbohydrate metabolism. Conclusions: Reference transcriptomes generated in this work represent a valuable resource to study Selaginella biology and plant evolution in relation to DT. -
PTERIDOPHYTE DIVERSITY in WET EVERGREEN FORESTS of SAKLESHPUR in CENTRAL WESTERN GHATS Sumesh N
Indian Journal of Plant Sciences ISSN: 2319–3824(Online) An Open Access, Online International Journal Available at http://www.cibtech.org/jps.htm 2014 Vol.3 (1) January-March, pp. 28-39/Dudani et al. Research Article PTERIDOPHYTE DIVERSITY IN WET EVERGREEN FORESTS OF SAKLESHPUR IN CENTRAL WESTERN GHATS Sumesh N. Dudani1, 2, M. K. Mahesh2, M. D. Subash Chandran1 and *T. V. Ramachandra1 1Energy and Wetlands Research Group, Centre for Ecological Sciences, Indian Institute of Science, Bangalore – 560 012 2Department of Botany, Yuvaraja’s College (Autonomous), University of Mysore, Mysore - 57005 ABSTRACT The present study deals with the diversity of pteridophytes in the wet evergreen forests of Sakleshpurtaluk of Hassan district in central Western Ghats. A significant portion of the study area comprises of the Gundia river catchment region which is considered to be the ‘hottest hotspot of biodiversity’ as it shelters numerous endemic and threatened species of flora and fauna. Survey of various macro and micro habitats was carried out in this region, also a haven for pteridophytes. A total of 45 species of pteridophytes from 19 families were recorded in the study. The presence of South Indian endemics like Cyathea nilgirensis, Bolbitissub crenatoides, B. semicordata and Osmunda huegeliana signifies the importance of this region as a crucial centre of pteridophytes. Similar regions in the Western Ghats, rich in network of perennial streams have been targeted widely for irrigation and power projects. With regard to an impending danger in the form a proposed hydro-electric project in the Gundia River, threatening the rich biodiversity, an overall ecological evaluation was carried out in the entire river basin. -

Investigating Water Responsive Actuation Using the Resurrection Plant Selaginella Lepidophylla As a Model System
Investigating Water Responsive Actuation using the Resurrection Plant Selaginella lepidophylla as a Model System Véronique Brulé Department of Biology McGill University, Montréal Summer 2018 A thesis submitted to McGill University in partial fulfillment of the requirements of the degree of Doctor of Philosophy © Véronique Brulé 1 ! ABSTRACT Nature is a wealth of inspiration for biomimetic and actuating devices. These devices are, and have been, useful for advancing society, such as giving humans the capability of flight, or providing household products such as velcro. Among the many biomimetic models studied, plants are interesting because of the scope of functions and structures produced from combinations of the same basic cell wall building blocks. Hierarchical investigation of structure and composition at various length-scales has revealed unique micro and nano-scale properties leading to complex functions in plants. A better understanding of such micro and nano-scale properties will lead to the design of more complex actuating devices, including those capable of multiple functions, or those with improved functional lifespan. In this thesis, the resurrection plant Selaginella lepidophylla is explored as a new model for studying actuation. S. lepidophylla reversibly deforms at the organ, tissue, and cell wall level as a physiological response to water loss or gain, and can repeatedly deform over multiple cycles of wetting and drying. Thus, it is an excellent model for studying properties leading to reversible, hierarchical (i.e., multi length-scale) actuation. S. lepidophylla has two stem types, inner (developing) and outer (mature), that display different modes of deformation; inner stems curl into a spiral shape while outer stems curl into an arc shape. -

PhytoKeys 78: 83–107. https://doi.org/10.3897/phytokeys.78.12040 Abstract The monotypic fern genusDryopolystichum Copel. combines a unique assortment of characters that ob- scures its relationship to other ferns. Its thin-walled sporangium with a vertical and interrupted annulus, round sorus with peltate indusium, and petiole with several vascular bundles place it in suborder Poly- podiineae, but more precise placement has eluded previous authors. Here we investigate its phylogenetic position using three plastid DNA markers, rbcL, rps4-trnS, and trnL-F, and a broad sampling of Polypodi- ineae. -

Erstgutachter: Prof. Dr. Georg Miehe (Marburg) Zweitgutachterin: Prof. Dr. Maaike Bader Tag der mündlichen Prüfung: 25.04.2018 i Preface This study is part of an interdisciplinary research project in one of the least known mountain areas of Asia. Only the recent opening of Myanmar offered the unique possibility to conduct species diversity and mountain ecology research in an area, which harbors the last remaining virtually untouched forests of the Himalayas and possibly of Southeast Asia. Although three extensive expeditions were able to collect a unique dataset, I am fully aware that our results are preliminary and this area offers more to explore. However, I hope that this thesis can contribute to a better understanding of mountain biodiversity patterns and may provide enough incentives for future projects. This cumulative thesis submitted here includes first evaluations of datasets from the expedition areas in northern Myanmar, and connects these data with those from other mountain areas of East and Southeast Asia (see the list below).

During a sojourn of more than one hundred days, we observed and collected a comprehensive number of fern species as well as flowering plants and mosses. Here is given an enumeration of all pteridophytes collected on this trip. In this paper, however, only a list of the specific identifications of the collections has been made. In the course of the investigation of the fern flora of Thailand, we met with a good many facts new to science. This information will be forthcoming in other publications. The field work of the Expedition was accomplished by the following four Japanese botanists and a Thai entomologist, who accompanied the Japanese group from beginning to end: Motozi T AGAWA, the leader, on pteridophytes and general botany Kunio IWATSUKI, on pteridophytes Naofumi KITAGAWA, on bryophytes Nobuyuki FUKUOKA, on flowering plants in general Dumrong CHAIGLOM, on entomology in relation to forestry.

I attended a fern botanising course in the Cairngorms in Scotland a few years ago and there learnt the immeasurable educational value of seeing plants in their natural habitat. As my Horticultural career progressed, my focus turned more towards Tropical plants and I became employed at the glasshouses in Kew Gardens. At this point, the world of Tropical ferns was opened up to me and a whole new phase of my long-standing interest was born. It therefore seemed natural to apply for a travel bursary to see Tropical ferns in-situ, and take the opportunity to delve more deeply into the entire world of Pteridophytes. Pteridophytes of all shapes and sizes form a significant part of the flora in ecosystems all over the world, and can be found from sea level to high mountains. There are considered to be roughly 13,000 species of fern today, and despite lacking flowers, the diversity of their appearance is astonishing.
