Glyoxalase I expression pattern in Hevea brasiliensis seedlings under varied stress conditions

Drought is one of the most important stress factors which adversely affect plants’ growth and productivity. Global climate change may make this situation more serious in the years ahead.  Considering the long time span required for the generation of drought resistant genotypes in Rubber (Hevea brasiliensis) through conventional breeding, molecular interventions to engineer plants to have either drought...

Nutritional food content of seed and effects of five different growing media on the seed germination and seedling growth of Afzelia africana SM Caesalpiniaceae

Nutritional food content of seed and effect of five different growing media: Top forest soil (TS), sawdust (SD), 2:1 mixture of; TS+SD, TS+composted poultry manure (TS+PM) and 2:1:1 mixture of TS+SD+PM on the seed germination and seedling growth of Afzelia Africana SM Caesalpiniaceae  were investigated. Thirteen chemical food nutrients were detected in the species seed. These occurred in varying percentages. The...

Response of African eggplants to Fusarium spp. and identification of sources of resistance

Eggplant (Solanum spp.) production in Arumeru district and other parts of Africa is severely affected by wilting diseases of unknown etiology. Fusarium spp. characterized through morphological and sequence analysis of the translation elongation factor associated with Fusarium wilt of eggplants was used to test the response of three different eggplant species. Three Solanum spp. accessions were tested in a screen house...

A commercial micropropagation protocol for virupakshi (AAB) banana via apical meristem

In vitro micropropagation of banana (Musa spp.) cv.virupakshi (Hillbanana) was studied. Suckers were collected from the germ plasm block of Jain R&D (originally established from the suckers from Palani Hills, Tamil Nadu) during summer. The sucker surface sterilized with 1% NaOCl for 30 min gave 100% survival without any contamination. Apical meristems that were isolated and cultured on MS based media supplemented...

Detection of extracellular enzymatic activity in microorganisms isolated from waste vegetable oil contaminated soil using plate methodologies

In the present study, from a total of 100 strains isolated from waste vegetable oil contaminated soil, 38 bacterial and 14 fungi strains that presented positive lipolytic activity were obtained by detection through Rhodamine B Agar 0.02% w/v as a screening method. Additionally, two other enzymatic activities were determined. Positive proteolytic activity was evaluated in Casein Hydrolysis Agar and chitinolytic activity...

Production of thermophilic and acidophilic endoglucanases by mutant Trichoderma atroviride 102C1 using agro-industrial by-products

Many traditional mutagenic strategies have been used to improve cellulase production by micro-organisms, especially fungi species. Trichoderma species are among cellulolytic fungi, those that have been most extensively studied, due to their efficient production of these enzymes. In the present study, N-methyl-N´-nitro-N-nitrosoguanidine (NTG) was used as mutagenic agent to obtain cellulolytic mutant from wild...

Genetic diversity and structure of goats within an early livestock dispersal area in Eastern North Africa

In this study we genotyped 14 microsatellites to assess genetic diversity, population stratification and demographic dynamics using Egyptian local goats (Zaraibi, Baladi, Saidi and Barki) and the Shami (Damascus) goat from the Middle East and West Asia close to the geographic center of goat domestication. We observed high levels of allelic and genetic diversity that was partitioned into six gene pools. Cluster analyses...

Histological and biochemical evaluations of the liver and kidney of Wistar rats fed with fish meal of Sarotherodon melanotheron captured with Tephrosia vogelii’s powder

To evaluate the toxicity of fish captured with Tephrosia Vogelii (TV), an ichtyotoxic plant, the Wistar albino rats were fed with the flour of tilapias Sarotherodon melanotheron poisoned with TV leaves powder. This study aimed to evaluate the poisonous effects of TV on various organs of rats, especially the liver and kidney. Three groups of Wistar rats were constituted and fed for 28 days. Histological sections were...
