Manganese (Mn) excess is a major abiotic stress for plant growth. In the present study, we investigated effects of Mn on photosynthesis in Ligustrum lucidum and Melia azedarach leaves using chlorophyll fluorescence transients. Both species were exposed to two concentrations (0.5 1 mmol) 10 30 d. Results showed that significantly inhibited photosynthesis. With increase concentration time, inhibi...

To each category C of modules of finite length over a complex simple Lie algebra g, closed under tensoring with finite dimensional modules, we associate and study a category AFF(C)κ of smooth modules (in the sense of Kazhdan and Lusztig [9]) of finite length over the corresponding affine Kac– Moody algebra in the case of central charge less than the critical level. Equivalent characterizations ...

Medicinal plants play a key role in human life as they are helpful in curing several diseases. They not only support health by the pharmacological nature but also utilizable as contraceptive options. The present study reveals that the medicinal plants Melia azedarach and Dodonaea viscosa leaf extracts showing antifertility activity. The decreased sperm count and reproductive organ weights inclu...

O fungo Penicillium sp foi isolado do córtex das raízes de Melia azedarach após a esterilização da superfície de seus tecidos e foi cultivado durante três semanas sobre arroz previamente esterilizado. Um novo meroterpeno, denominado austinoneol, e os meroterpenos já conhecidos 7-β-acetoxi-dehidroaustina, neoaustina e de-hidroaustina foram isolados do extrato metanólico desta cultura. Suas estru...

Penicillium janthinellum, isolado como um fungo endofítico dos frutos de Melia azedarach, foi cultivado por 20 dias em milho branco triturado e autoclavado, onde os policetídeos conhecidos citrinina, emodina, 1,6,8-triidróxi-3-hidroximetilantraquinona, e uma nova antraquinona modificada, denominada janthinona, foram produzidos e isolados por procedimentos cromatográficos clássicos e identificad...
