Life Sciences Leaflets is an international INTRODUCTION: open access print & Out of the estimated tens of millions of species on earth only about 1.7 million e journal, peer species could be described taxonomically [1]. Tropics which harbour the major reviewed, worldwide abstract listed, diversity of Earth’s species is under potential thread by global climate change published every month [2]. Global climate change is majorly due to human activities and possible with ISSN, RNI Free- future changes in the global climate is predicted by climatologists. With the membership, downloads and access. predicted climate change and no immediate change in the behaviour, there will be a drastic impact on the biosphere within just a few decades, with the number of species facing extinction estimated to be around one million by http://lifesciencesleaflets.ning.com/ PEER-REVIEWED Page | 1 Life Sciences Leaflets FREE DOWNLOAD ISSN 2277-4297(Print) 0976–1098(Online) 2050 [3]. Therefore, it requires the use of tools like DNA bar coding for quicker identification of species, in biological conservation such as biodiversity survey or when traditional methods are unrevealing i.e. identification of specimen from the remains of the specimens such as egg and larvae, analysis of stomach contents or excreta to determine the food webs [4]. A DNA barcode is a short, highly variable, standardized, orthologous DNA sequence use to identify species through comparison to a DNA sequence database [5]. DNA Bar coding construct a public reference library of species identifiers which could be used to assign unknown specimens to known species [6]. One such important plant under thread, whose number is declining, is Lilium mackliniae, the state flower of Manipur [Fig.no.1]. The plant is endemic to the state. The main threats to the species and habitats are frequent forest fire and rapid colonization by a dwarf bamboo after forest fire [7]. Uncontrolled visits by tourists and collection of the Lily has also led to its severe decline [8]. The word “Lilium” (latin) derives from leirion (Greek) used by Theophrastus for Madonna lily. Lilies are horticulturally classified in Division 9 under eight sub-divisions and Lilium mackliniae comes under subdivision “H” [9]. There are approximately 2000 lily species under 200 genera of the family Liliaceae. The genus Lilium comprises of 110 to 120 species [10]. The species of the genus Lilium have the largest genomes in plant kingdom with a haploid DNA content (1C) ranging from 32.75 to 47.90 pg, which makes it a difficult crop for molecular marker techniques [11]. After 60 years of the original discovery of Lilium mackliniae by Frank kingdom Ward in 1949 from Mount Siroi (2,700m), two more Lilium species have been claimed to be discovered and spread to two other mountains, viz. Mount Saramati (3,700m), Japvo (about 3,000m) with the three peaks approximately 100km apart [12]. There are 34 recognized biodiversity hotspots in the world which cover 2.3 percent of the Earth's land surface. These hot spots have been declined by 70 percent from their original vegetation coverage. But despite the decreasing size of these hotspots they are still the home to 50 percent of the world's plant species [13]. Observing the fast changing nature in the biodiversity, continuous thread in the Lilium population and unavailability of the taxonomic characteristic genomic sequence of the endemic lily in the GeneBank library (no research report published of the plant from Manipur, India, the native to the endemic L. mackiliniae), the present study of DNA bar coding of the endemic plant was carried out. METHODOLOGY: i) Plant material Lillium mackliniae was collected during June, 2007 from Siroi hill which is 1730m–2590m above sea level in Ukhrul district, located under 25° 7' 0N latitude and 94° 22' 0E longitude and an altitude of 1661m [14] of Manipur, India [Figure No.2], which experiences, subtropical hill and mid-temperate climate with wet summer and extreme cold, occasionally snowfall and dry winter. Plant siblings collected were planted under natural conditions without fertilizer in earthen pots at home at Imphal West, Manipur, located at 24.82°N, 93.95°E, average http://lifesciencesleaflets.ning.com/ PEER-REVIEWED Page | 2 Life Sciences Leaflets FREE DOWNLOAD ISSN 2277-4297(Print) 0976–1098(Online) elevation of 786metres [15] which is comparatively warmer or hotter and dryer than Siroi. The adaptability and survivality under warmer/hotter and dryer sub-tropical climate was observed. Herbarium voucher specimen is deposited at Manipur University, Kanchipur, Imphal, Manipur [MUID No.000817, 2012]. Plant material under fresh condition are performed DNA barcoding using chloroplast rbcL and matK genes with nuclear ribosomal ITS gene as markers. The DNA Sequences generated in the lab were blasted to NCBI BLAST with those available in GeneBank for checking their similar base sequences availability. The sequence of matK was not on report hence it is submitted to NCBI, USA [GenBank accession number KC539824], later it is release on May 5, 2013 and made it available to EMBL [Europe] and DNA Data Bank [Japan]. ii) DNA extraction, amplification and sequencing Genomic DNA was extracted from fresh leaves of Lillium mackliniae following the protocol associated with the Plant Genomic DNA Kit (Sigma GeneElute TM Plant Genomic DNA Miniprep kit, Sigma-Aldrich, Inc., USA). Polymerase chain reaction (PCR) of the chloroplast rbcL, matK and nuclear ribosomal ITS regions were carried out in a Mastercycler personal 120V (Eeppendorf, USA) using approximately 30ng of genomic DNA as a template in a 20 µl reaction mixture (2µl of 10 x PCR buffer without MgCl2, 2µl of 25mM MgCl2, 2µl of 2mM dNTPs, 0.5µl each of forward and reverse primers, 0.2 µl of (5u/ µl) Tag DNA polymerase (AmpliTaq Gold® 360 DNA Polymerase, 1000U, Biosystems, USA), and 9.8µl of HPLC grade distilled water. Universal primers such as rbcL primers, matK primers and ITS2 primers were used (CCDB, Canada). The PCR products were run on a 1.0% agarose gel in 0.5XTBE buffer and purified with ExoSAP-IT treatment by incubating to PCR at 37C for 1hr then at 85C for 15 mins. The purified PCR product was sequenced by Sanger dideoxy sequencing Technology under sequencing PCR conditions in GeneAmp® PCR System 9700 (Applied Biosystems Inc.) using 1µl (~20ng) of cleaned PCR product in a 10µl reaction volume (1.86µl of 5X sequencing buffer, 0.28 µl of Sequencing Mix (Big Dye Terminator, Applied Biosystems), 0.32µl of primer (forward/reverse-10 µM), 6.45µl of distilled water (HPLC grade)). The post sequence cleaning is done using in master mix of 5 µl distilled water, 0.1 µl 0.5M EDTA and 1 µl of 3M sodium acetate and 44 µl of ethanol per 10 µl sequence PCR reaction. The cleaned up sequence is air dried and sequenced in ABI 3730DNA Analyzer (Applied Biosystems). Gene scan is done in 1.0 µl PCR product using ABI 3730 in the sample volume of 20 µl obtained from the mixture of 20 µl Hi-Di Formamide and 0.5 µl of GeneScan 600 Liz-Size standard. http://lifesciencesleaflets.ning.com/ PEER-REVIEWED Page | 3 Life Sciences Leaflets FREE DOWNLOAD ISSN 2277-4297(Print) 0976–1098(Online) iii) Sequence alignment and data analysis: Separate sequences forward (F) and reverse (R) were obtained for each of the chloroplast rbcL and chloroplast matK and nuclear ribosomal ITS marker genes of Lillium mackliniae and extracted the sequences using Sequence Scanner (Applied Biosystems) and by alignment following Assembly Method using Geneious Pro 5.0.3, the consensus sequences for each of the markers were obtained. The consensus sequences of the each of the markers were perform nucleotide BLAST to confirm whether marker sequence of the plant is already in the GeneBank and so as to make a new submission or if already submitted confirming for the correct identification and checking of the best BLAST hit for the query sequence. RESULT: Measurement of DNA Sequences alignment for Lillium mackliniae for matK and ITS2 markers in nucleotide BLAST shows 100% similarity score with the one reported in NCBI, GeneBank from Japan. There was no sequence report for rbcL genes and was submitted as a new sequence submission by direct submission to NCBI and was assigned with the accession number KC539824. The sequence results for matK and ITS are comparatively inferior than rbcL as both contains wrong and mismatch pair with a few stop codons within the length of the sequences. No phylogenetic tree is constructed as the study focuses on the submission of the new rbcL marker sequence to GeneBank for open access and public use and not on their phylogeny.

Various methods in tissue culture and molecular breeding have been applied to the production of commercially important lily species and cultivars. However, scientific research data of such species and varieties that have potential in the northern climate is scarce. In this work, different biotechnological methods were developed and used in the production and culture of a diversity of lily species belonging to different taxonomic groups. The aim was to test and develop further the existing methods in plant biotechnology for the developmental work and the production of novel hardy lily cultivars for northern climates.

Gianfagna The Easter lily (Lilium longiflorum Thunb., Liliaceae) has beautiful white flowers and a delicate aroma and is appreciated worldwide as an attractive ornamental plant. In addition to its economic importance and popularity in horticulture, lily bulbs are regularly consumed in Asia, as both food and medicine. The Easter lily is a rich source of steroidal glycosides, a group of compounds that may be responsible for some of the traditional medicinal uses of lilies and may play a role in the pant-pathogen interaction. This research project was designed to: 1) Isolate and characterize new steroidal glycosides from the bulbs of L. longiflorum, 2) quantify their contents in all of the organs of L. longiflorum, and 3) perform studies on the antifungal activity and fungal metabolism of the compounds. A phytochemical investigation conducted on the bulbs resulted in the discovery of several novel steroidal glycosides.
