The Orchid MADS-Box Genes Controlling Floral Morphogenesis
Review Article Special Issue: Evolution of MADS-box genes in Monocots TheScientificWorldJOURNAL (2006) 1, 109–120 TSW Development and Embryology ISSN 1537-744X; DOI 10.1100/tswde.2006.321 The Orchid MADS-Box Genes Controlling Floral Morphogenesis Wen-Chieh Tsai1 and Hong-Hwa Chen1,2,* 1Department of Life Sciences and 2Institute of Biotechnology, National Cheng Kung University, Tainan 701, Taiwan E-mail: [email protected] Received May 15, 2006; Accepted June 29, 2006; Published July 14, 2006 Orchids are known for both their floral diversity and ecological strategies. The versatility and specialization in orchid floral morphology, structure, and physiological properties have fascinated botanists for centuries. In floral studies, MADS-box genes contributing to the now famous ABCDE model of floral organ identity control have dominated conceptual thinking. The sophisticated orchid floral organization offers an opportunity to discover new variant genes and different levels of complexity to the ABCDE model. Recently, several remarkable research studies done on orchid MADS-box genes have revealed the important roles on orchid floral development. Knowledge about MADS-box genes’ encoding ABCDE functions in orchids will give insights into the highly evolved floral morphogenetic networks of orchids. KEYWORDS: orchids, MADS-box genes, ABCDE model, floral development, floral morphogenetic networks INTRODUCTION With more than 270,000 known species, angiosperms are by far the most diverse and widespread group of plants. The ancestry of the angiosperm is still uncertain. The fossil records show that the angiosperms appear at the early Cretaceous period, about 130 million years ago. By the end of the Cretaceous, 65 million years ago, the angiosperms had radiated and become the dominant plants on Earth, as they are today. -

Shakuntala Manay Here is Nagesh’s story, the first recipient of TOSKAR Rolling Shield for the Best Orchid. His interest in growing plants started as a child of eight when he would pick up sprouting onions from Mom’s kitchen onion and plant them in the yard and watched them grow into green leeks. This got him into the hobby to grow vegetables. By this time he was 14. Later he turned to growing foliage plants like succulents, Anthuriums and Cacti. Thus he dared to enter into annual shows at Lalbagh and won many prizes. In “small homes garden” categories he won eight awards from Urban Art Commission such as “Best Maintained Building & Garden” “Pride of Bangalore” “Role of Honour” etc. Ex- commissioners of Bangalore City Corporation Late N. Laxman Rao and Late Mr. Parthsarathy would visit his house as Judges. He received these prestigious prizes amidst distinguished guests and dignitaries at Rajbhavan. Trophies gathered so fast that there was no place for them at home. Twenty years ago he got one orchid from Indo American Nursery. Thus he began collecting orchids from Kerala, North East India and Western Ghats. Now on his terrace of 800 sq ft he has 1500 orchids! Among these Dracula Orchid (Monkey face) which grows in cloud mountains of Mexico, Central America and Colombia is one of his special collections, and more than 15 varieties of Carnivorous Plants and many Tillandsias also add to his collection. -

These authors contributed equally to the works. y Received: 15 March 2020; Accepted: 9 April 2020; Published: 10 April 2020 Abstract: Dendrobium has been widely used not only as ornamental plants but also as food and medicines. The identification and evaluation of the genetic diversity of Dendrobium species support the conservation of genetic resources of endemic Dendrobium species. Uniquely identifying Dendrobium species used as medicines helps avoid misuse of medicinal herbs. However, it is challenging to identify Dendrobium species morphologically during their immature stage. Based on the DNA barcoding method, it is now possible to efficiently identify species in a shorter time. In this study, the genetic diversity of 76 Dendrobium samples from Southern Vietnam was investigated based on the ITS (Internal transcribed spacer), ITS2, matK (Maturase_K), rbcL (ribulose-bisphosphate carboxylase large subunit) and trnH-psbA (the internal space of the gene coding histidine transfer RNA (trnH) and gene coding protein D1, a polypeptide of the photosystem I reaction center (psaB)) regions. -

Sporadic floristic exploration has been made for as long as 60 years but no more than 60 species of orchids had ever recorded. Thus, the intensive orchid exploration in Phu Kradueng plateau was conducted from October, 2014 to February, 2016. Together with herbarium specimens and orchid’s census data, it was suggested that as many as 111 species of orchids should have been found on the plateau. Thus far, however, only 78 species had been recorded, and as many as 33 species still have not been seen in this study. Possible causes include illegal smuggling of wild orchids, habitat losses and changes caused by severe wild fires and climate changes. Keywords: orchids, Phu Kradueng National Park, Loei 1. Introduction Sanctuaries, Forest Parks, and reserved forest. However, the Orchidaceae in the “Flora of Thailand” has not been Orchidaceae is one of two largest families of flowering completed; reports on area-based “catalogs” of orchids still plants, consisting of about 27,800 accepted species in 736 remain largely undone. -

North Point, District Darjeeling, (WB) - India Abstract Assam is one of the eight North East Indian states and Orchids are the major component of the vegetation at different climatic conditions. The agroclimatic condition of Assam is most congenial for the lavish growth and development of wide varieties of Orchid species in natural habitat. During pre-independence time, Hooker (1888 – 1890) in his work Flora of British India include about 350 species of Orchids from Assam- the present North East India. Present paper deals with checklist of 398 specific and 6 intraspecific taxa belonging 102 genera of Orchids in Assam out of which 129 species under 49 genera are terrestrial and 275 specific and intraspecific under 53 genera are epiphytic or lithophytic. Dendrobium represents the largest genus with 58 taxa and 51 are monotypic genera found in the regions. Key-Words: Checklist, Orchid Species, Assam, North East India Introduction Assam found in the central part of North-East India. It extends between the latitudes of 24°8´ N – 28°2´ N and The Brahamaputra valley: The Brahamaputra valley longitudes of 89°42´ E – 96° E.
