  • Ethnobotanical plants of Veligonda Hills, Southern Eastern Ghats, Andhra
           Pradesh, India

    • Authors: S K M Bhasha, P Siva Kumar Reddy
      Pages: 1 - 11
      Abstract: The Veligonda range which separates the Nellore district from Kadapa and Kurnool is the back bone of the Eastern Ghats, starting from Nagari promontory in Chittoor district. It runs in a northerly direction along the western boarders of the Nellore district, raising elevation of 3,626 feet at Penchalakona in Rapur thaluk. Veligonda hill ranges have high alttudinal and deep valley. These hills have rich biodiversity and many rare, endangered, endemic and threatned plants are habituated in these hills. The present paper mainly deals with the ethanobotanical plants used by local people.

  • Molecular characterization of two AP2/ERF transcription factor genes from
           Egyptian tomato cultivar (Edkawy)

    • Authors: Kareem Mosa, Eslam Heb El-din, Ahmed Ismail, Fawzy El- Feky, Ali El-Refy
      Pages: 12 - 20
      Abstract: The tomato is ranked first amongst vegetable crops in Egypt in relation to surface area and production. The Egyptian tomato cultivar Edkawy has shown abiotic stress tolerance characteristics. However, there is not much information about the molecular characterization of this cultivar. Furthermore, information regarding the identification of abiotic stress tolerance genes from the Edkawy tomato cultivar is lacking. Here, we investigated the ability of the Edkawy cultivar to tolerate drought stress. Two varieties were used as a control in this study; Peto86 (sensitive variety) and Strain B (tolerant variety). Edkawy, Peto86 and Strain B varieties were exposed to drought stress by reducing the water supply gradually. Interestingly, Edkawy demonstrated a remarkable tolerance phenotype to drought stress. Furthermore, we identified and isolated two members of the AP2/ERF transcription factor family from Edkawy which are associated with abiotic stress, particularly drought, i.e. ERF1 and ERF5. Protein prediction, validation and active site prediction of ERF1 and ERF5 were also determined. In addition to the domain obtained by the pfam online tool, the interaction between Edkawy ERFs proteins and other proteins in the Solanaceae family was obtained. Furthermore, subcellular localization was determined by the ngLOC and Plant-mPLoc online tools. Characterization of the Edkawy tomato cultivar and isolation and identification of such transcription factors will help in the engineering of tomato plants with abiotic stress tolerance.

  • In vitro conservation protocol of Ceropegia bulbosa: An important
           medicinal and threatened plant species of Western Rajasthan

    • Authors: Suman Parihar
      Pages: 21 - 27
      Abstract: In vitro regeneration protocol has been standardized for highly medicinal and threatened succulent Ceropegia bulbosa Roxb. The paper focuses on morphogenic response of nodal explant when cultured on MS media. Murashige and Skoog medium supplemented with 6-benzyladenine (BA) (2.0 mgl-1) was found optimum for axillary shoot bud induction with 83.4 % response. Further shoots were multiplied through repetitive (3-4 times) transfer of the original explant and by subculture of the in vitro generated shoots. Maximum number of shoots 5.7±0.78 with shoot length of 3.6±0.82 cm was achieved on MS medium augmented with combination of 0.25 mgl-1 BA + 0.25 mgl-1 KN + 0.1 mgl-1 IAA and additives (50.0 mgl-1 ascorbic acid, 25 mgl-1 each of citric acid, arginine and adenine sulphate). For ex vitro rooting, pulse treatment of IBA 250 mgl-1 for 3 min was found optimum. The rooted shoots were successfully hardened in the green house condition (RH 75-80% at 26-28˚C) and about 80 % shoots were transferred to the garden.

  • Amelioration of salinity stress by NaCl pretreatment with reference to
           sugar metabolism in legumes Cajanas cajan L. and Vigna mungo L.

    • Authors: Paramita Chatterjee, Sabarni Biswas, Asok Kumar Biswas
      Pages: 28 - 40
      Abstract: The effect of salinity stress and its amelioration by pretreatment with low concentration of NaCl (50mM) on growth and sugar metabolism in arhar (cv. T120) and maskalai (cv. WBU109) seedlings were studied. Salinity was found to be more toxic for root growth than shoot growth. Fresh weight and dry weight of the seedlings gradually decreased with increasing concentrations of NaCl treatment. It was demonstrated that direct germination on NaCl solution increased both reducing sugar and non-reducing sugar contents while decreased the starch contents which were to some extent decreased by pretreatment of seeds with 50mM NaCl prior to germination in salt solutions. Salinity stress also affected the activites of different sugar metabolizing enzymes. The increase in the activities of starch phosphorylase, sucrose phosphate synthase, sucrose synthase and decrease in the activities of acid invertase were observed in directly salt treated test seedlings that were altered by pretreatment with sublethal concentration of NaCl in both the cultivars arhar (cv. T120) and maskalai (cv. WBU109) seeds. Thus the application of pretreatment by sublethal concentration of NaCl in both arhar (cv. T120) and maskalai (cv. WBU109) seeds exhibited significant alteration of all the partinent parameters tested under salinity stress and the effect of pretreatment in most of the parameters were more prominent in arhar (cv. T120) with compared to maskalai (cv. WBU109) seedlings.

  • Bryophyte diversity of Thamarassery pass (Wayanad pass) in the Western
           Ghats of Kerala

    • Authors: Mithun Venugopal, Manju C Nair
      Pages: 41 - 48
      Abstract: The bryophyte diversity in the Thamarassery pass (Wayanad pass) a historically important place of Kozhikode district is documented. This report represents many interesting finds such as Taxiphyllum giraldii (C.Muell.) M.Fleisch., Taxithelium laeviusculum Dixon are new records for Peninsular India.

  • Checklist of Mosses (Bryophyta) of Bodamalai Hills in Eastern Ghats, Tamil
           Nadu

    • Authors: R Palani, S Sahaya Sathish, T Thamizharasi, P Vijayakanth
      Pages: 49 - 54
      Abstract: Bodamalai Hills, situated on the Southern Eastern Ghats of Tamil Nadu, were explored for mosses (bryophyta) for the first time. As a result a checklist of mosses has been prepared comprising 52 species belonging to 38 genera and 21 families. The dominant families with the maximum number of species are Pottiaceae, Bryaceae, Stereophyllaceae, Sematophyllaceae and Brachytheciaceae. The dominant genera are Brachymenium and Bryum and the dominant species are Barbula javanica and Bryum capillare.
