Trichoderma as biological control weapon against soil borne plant pathogens

The genus of Trichoderma is widely applied for the biocontrol of phytopathogenic fungi in agriculture sector. Moreover, Trichoderma species are also excessively exploited in different industrial purposes due to their production of important lytic enzymes such as chitinases, glucanases and proteases. Several genetic improvement trials are carried out for maximizing the role of Trichoderma as biological control agents via...

Overexpression of key enzymes of the 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway for improving squalene production in Escherichia coli

2-C-Methyl-D-erythritol-4-phosphate (MEP) pathway has been extensively employed for terpenoids biosynthesis in Escherichia coli. In this study, to obtain key-enzymes of MEP pathway for squalene production, overexpression of different combination of MEP pathway genes were compared. Squalene production in strain YSS12 with overexpressed dxs, idi and ispA of MEP pathway from E. coli was improved by 71-fold when compared...

Genetic and population diversity of bacuri (Platonia insignis Mart.) in Chapada Limpa extractive reserve, Maranhão State, Brazil

Landscape studies illustrate how the structure and configuration of ecological/agroecological zones influence the genetic diversity of a species. Thus, the aim of the present study is to assess how landscape structure and conservation influence the genetic diversity indices of Platonia insignis Mart. (bacuri) in Chapada Limpa Extractive Reserve, Chapadinha County, Maranhão State, Brazil. The study was carried out...

Evaluation of serum sialic acid and other risk factors in diabetes mellitus

The main cause of diabetes mellitus type 2 (DM2) is disturbed carbohydrate metabolism indicated by hyperglycemia. Insulin secretion is disturbed by inflammatory process in the body due to imbalanced diet, hormonal disturbance and genetics. The serum sialic acid has been investigated as a parameter to evaluate intensity of DM2. 200 individuals of both genders were included and were divided into four groups (50 each)...
