Analysis of the genetic diversity of selected East African sweet potato (Ipomea batatas [L.] Lam.) accessions using microsatellite markers

Sweet potato (Ipomea batatas [L.] Lam.) is an economically important crop in East Africa chiefly grown by small holder farmers. Sharing of vines for planting is a very common occurrence among these farmers and eventually varieties are given local names, making it hard to trace the original pedigree. It is therefore important to characterise the sweet potato germplasm for purposes of breeding and germplasm conservation....

Impact of the application of humic acid and sodium nitroprusside on nickel toxicity: Analysis of relative gene expression

Nickel (Ni) is an essential micronutrient for plants but in high concentrations may turn toxic. This paper discusses the potential role of humic acid (HA) and sodium nitroprusside in modulating or preventing oxidative stress in rice plants. Three genes [superoxide dismutase (SOD) glutathione reductase (GR) and ascorbate peroxidase (APx) were selected for an expression study using a real time PCR technique. Three...

Screening of successive extracts of Amorphophallus konjac for antibacterial activity

Amorphophallus is an Aroid family member, native to Asia. Amorphophallus konjac K. Koch ex N.E.Br. is also known as snake plant due to snake like outlines on its stem. In Mount Abu the plant is grown in wild and known for its toxic principles. In Traditional Chinese System of Medicine (TCM), it was mentioned that gel prepared from flour has been used in detoxification, tumor suppression, phlegm liquefaction and skin...

Lipid lowering and anti-atherosclerotic properties of Tinospora crispa aqueous extract on high-cholesterol diet-induced hyperlipidemic rabbits

This study was aimed to investigate the hypocholestrolemic and anti-atherosclerotic properties of Tinospora crispa aqueous extract (TCAE) on rabbits for 10 weeks. The hyperlipidemic rabbits were induced and the rabbit were given different concentration of TCAE (200, 450 and 600 mg/kg). Results from lipid analysis show that the level of total cholesterol (TC), triglyceride (TG) and LDL-C on the hyperlipidemic rabbits...

The inhibitory effect of Lactobacillus sakei KBL isolated from kimchi on the adipogenesis of 3T3-L1 cells

Abnormal adipocyte growth, in terms of increased cell numbers and increased cell differentiation, is considered to be a major pathological feature of obesity. Thus, the inhibition of preadipocyte mitogenesis and differentiation could help prevent and suppress obesity. Some probiotics and cellular components are known to modulate the lipid metabolism in vitro and/or in vivo. The aim of this study was to investigate...
