On the other hand, fallen leaves cover a larger area Raffles Institution and can be found more easily. Singapore, Singapore 2. Hypothesis The usage of GLCM features as a computational approach Abstract - This paper briefly describes two methods used to to identify Hopea sangal, Shorea pauciflora, Anisoptera differentiate leaves of five species, Anisoptera megistocarpa, Dipterocarpus grandiflorus and Vatica megistocarpa, Dipterocarpus grandiflorus, Hopea sangal, maingayi achieves a higher accuracy than the usage of a Shorea pauciflora and Vatica maingayi, that belong to the dichotomous key. Dipterocarpaceae family. The two methods are: a) the traditional approach, namely, a dichotomous key and b) the 3. Method and materials computational method which consists of the use of Gray Level Co-occurrence Matrix (GLCM). Through the two approaches, we then compare the accuracy rates in identifying the leaf species by running tests using both methods. GLCM achieved an overall identification accuracy of 93.3%, while the dichotomous key achieved an average Fig 1. Overview of methodology accuracy rate of 85%. 3.1. Species selection and Data collection The sample species were selected based on three criteria, Keywords: dichotomous key, Gray Level Co-occurrence using the Checklist of Total Vascular Flora of Singapore. Matrix The first criterion is the native status of each species. All the chosen species are locally cultivated so that educators and amateur botanists would be able to identify the trees they 1.

Characterization of a Type 3 Metallothionein Isolated from Porteresia Coarctata
BIOLOGIA PLANTARUM 55 (1): 119-124, 2011 Characterization of a type 3 metallothionein isolated from Porteresia coarctata B. USHA, N.S. KEERAN, M. HARIKRISHNAN, K. KAVITHA and A. PARIDA* Plant Molecular Biology Laboratory, M.S. Swaminathan Research Foundation, Taramani, Chennai-600113, India Abstract Metallothioneins are involved in detoxification of heavy metals. A cDNA encoding type 3 metallothionein (PcMT3) was isolated from the salt stressed leaf cDNA library of Porteresia coarctata (Roxb.) Tateoka (wild rice) that grows well in the heavy metal laden estuarine soils. The PcMT3 cDNA (581 bp) encodes a protein of 64 amino acids. PcMT3 is highly homologous (82 %) to OsMT-I-3a of rice, but is unique from other type 3 plant MTs due to the presence of an additional glycine residue in the C-terminal domain. Analysis of the 5′ upstream region of PcMT3 showed the presence of cis-acting elements like the CG box and STRE previously reported to be involved in gene expression under heavy metal stress. Southern analysis suggested the presence of more than one copy of PcMT3-like sequences in the P. coarctata genome. Analysis of genomic clone of PcMT3 revealed the presence of two introns. A comparison of the genomic sequence of PcMT3 with closely similar type 3 MTs from rice and mangrove species revealed conservation in the number and position of introns. Transcript profiling for PcMT3 in P. coarctata leaves in the presence of Cd, Cu and Zn showed an increase in transcript accumulation. Additional key words: cis-acting elements, heavy metals, salt stress, wild rice. Introduction Plants acquire heavy metal tolerance through various reported in plants like rice, hybrid poplar, oil palm and mechanisms like compartmentalization, sequestration, lichens (Abdullah et al. -

In this study, oil was extracted from the seed by conventional soxhlet extraction with n-hexane and ultrasonication technique. Seeds without wing were found to contain about 15% oil for 6 hours soxhlet extraction at 50°C and 45 minutes ultrasonication at 40°C. Fatty acid composition of the soxhlet extracted oil analyzed by GC-FID showed stearic acid and oleic acid as the major components. Acid value, iodine value, saponification value, peroxide value, refractive index, viscosity were also determined. Thermogravimetric analysis of the oil for the determination of the thermal stability of the oil. Transesterification and Saponification process were carried out to produce Biodiesel and the soap from the extracted seed oil. The produced biodiesel and the soap were characterized and a comparative studies were carried out with international standards. The optimum yield for biodiesel was found around 40% of the raw materials and the cytotoxic analysis of the produced soap were carried out. The integrated production of biodiesel and soap from Sal seed oil will bring a drastic change in the realization fuel and cosmetic industries. -

Study Design: Kola nuts were purchased in open markets within South Western, Nigeria. Place and Duration of Study: The samples were obtained in markets within Oyo, Osun and Ogun States, Nigeria between November and December, 2012. Methodology: Kola nuts were sun-dried and pulverized. 3 g of each of the pulverized samples was extracted with acetonitrile saturated with hexane. Each of the extracts was subjected to clean-up followed by pesticide residue determination using HP 5890 II Gas Chromatograph. Results: Result show that, 50% of kola nuts samples obtained from Oyo State contained chlordane residue ranging from nd – 0.123 µg kg-1; all the samples from Osun State had chlordane residue ranging from 0.103 to 0.115 µg kg-1 while 70% of kola nuts from Ogun State had chlordane residues (nd – 0.12 µg kg-1). -

To describe reproductive phenological stages, since the formation of flower buds, flowering, fruiting, up to the formation of the ripe fruit and foliation of 21 Couepia polyandra trees; and correlation of allometric data of tree height, diameter at breast height (DBH) and crown diameter, as well as the correlation of precipitation with reproductive phenology data. Methodology. The description of the reproductive phenology (foliage, formation of flower buds, flowers, fruits) was done by direct monthly observation with a digital camera (Canon SX60HS, 65). The correlation among precipitation, allometry, and types of soils where the trees grow was calculated by recording data from each tree by measuring height, diameter at breast height (DBH) and foliage. Results. The highest tree was 21.0 m; the widest DBH measured 68 cm; and the greater crown diameter was 34.45 m; the overall averages were 10.38 m, 33.17 cm and 9.37 m, respectively. A significant correlation was found between height and DBH (r0.91, p0.05); the correlations for the variables Height-Crown and DBH-Crown were not significant (p0.05). Conclusions. Water as a factor is responsible for the formation of inflorescence and fruit; determining that these phenological events are dependent variables with precipitation, highlighting a mean positive relation with the growth of flowers.
