Screening of endophytic bacteria isolated from leaves of Sambung Nyawa [Gynura procumbens (Lour.) Merr.] for cytokinin-like compounds
UNLABELLED Endophytic bacteria are harmless in most plant species; and known to boost the growth and development of the host plants probably by secreting growth hormones. The isolation, identification and screening of endophytic bacteria for the plant growth regulators like cytokinin are needed to get the leads for their applications in agriculture sector. We describe the isolation and identifi...
متن کاملTranscriptome data of Epinephelus fuscoguttatus infected by Vibrio vulnificus
Vibriosis disease by Vibrio spp. greatly reduced productivity of aquaculture, such as brown-marbled grouper (Epinephelus fuscoguttatus), which is an economically important fish species in Malaysia. Preventive measures and immediate treatment are critical to reduce the mortality of E. fuscoguttatus from vibriosis. To investigate the molecular mechanisms associated with immune response and host-b...
متن کاملEffect of Cadmium and Copper Exposure on Growth, Secondary Metabolites and Antioxidant Activity in the Medicinal Plant Sambung Nyawa (Gynura procumbens (Lour.) Merr).
A randomized complete block (RCBD) study was designed to investigate the effects of cadmium (Cd) and copper (Cu) on the growth, bioaccumulation of the two heavy metals, metabolite content and antibacterial activities in Gyanura procumbens (Lour.) Merr. Nine treatments including (1) control (no Cd and Cu); (2) Cd 2 = cadmium 2 mg/L; (3) Cd 4 = cadmium 4 mg/L; (4) Cu 70 = copper 70 mg/L; (5) Cu 1...
متن کاملAntiherpetic Effects of Gynura procumbens
The ethanol extract of Gynura procumbens showed virucidal and antireplicative actions against herpes simplex virus HSV-1 and HSV-2. It was further chromatographed on MCI gel CHP20P column giving the extract fractions F1 (water), F2 (water-methanol) F3 (methanol), and F4 (ethyl acetate). All but F1 had virucidal action against both viral types. We reported here the active compounds from F2 and F...
متن کاملتغییرات هیستوپاتولوژیک کلیه ماهی هامور معمولی (Epinephelus coioides) تحت تاثیر بنزوآلفاپایرن و باکتری (Vibrio alginolyticus)
بنزوآلفاپایرن(BaP) از سمیترین ترکیبات موجود در نفت خام است که با آلودگی اکوسیستمهای آبی، موجب تضعیف سیستم ایمنی آبزیان و کاهش مقاومت آنها در برابر پاتوژنهای فرصت طلب میشود. باکتری V. alginolyticus گونهای از این پاتوژنهای فرصت طلب است که در شرایط استرسزا، موجب بیماری ویبریوزیس در موجودات مختلف میگردد. بهمنظور بررسی تغییرات هیستوپاتولوژیک ناشی از تاثیر دو استرسور BaP و باکتری V. alginoly...
