A study was carried out to determine the effects of paraquat, pretilachlor and 2, 4-D on growth and nitrogen fixing activity of Stenotrophomonas maltophilia (Sb16) and pH of Jensen’s N-free medium. The growth of Sb16 and pH of medium were significantly reduced with full (X) and double (2X) doses of tested herbicides, but nitrogen fixing activity was decreased by 2X doses. The nitrogenase activity...
β-Galactosidase (EC 3.2.1.23) is a hydrolase which plays an important role in cell wall modification and fruit softening during ripening. In this study, three fulllength β-galactosidase cDNA clones were successfully obtained from papaya mesocarp using different approaches. pPGBII which is 2,771 bp in size, was isolated from a papaya ripe mesocarp cDNA library using a heterologous probe. The other...
Elicitation, the plant-based biotechnology approach that utilizes the ability of plant roots to absorb and secrete a vast variety of bioactive compounds, was studied on Polygonum minus using jasmonic acid (JA) as an elicitor. To understand the overall molecular responses of P. minus roots to JA induction, a subtracted cDNA library was constructed using the suppression subtractive hybridization (SSH)...
