The genus Labisia (Myrsinaceae) is a popular medicinal plant in Malaysia. We examined the genetic relationship among three varieties of L. pumila var. pumila, L. pumila var. alata, L. pumila var. lanceolata and Labisia paucifolia using an ISSR assay. Fifty-eight primers were tested, among which 18 gave reliable polymorphic banding patterns; these yielded 264 polymorphic markers. A similarity ma...

BACKGROUND Polymalic acid (PMA) has many applications in food and medical industries. However, so far it has not been commercially produced by fermentation. Therefore, it is very important how to develop an economical process for a large scale production of PMA by one step fermentation. RESULTS After over 200 strains of Aureobasidium spp. isolated from the mangrove systems in the South of Chi...

Investigation of allelopathic substances from herbal plants may lead to the development allelochemical-based natural herbicides. Croton oblongifolius (Roxb.) is a well-known plant with long history being used for traditional medicines and source diverse range bioactive compounds. This has been reported have potential; however, its allelopathic-related not yet described. Therefore, we conducted ...

In recent years strains previously grouped within Cryptococcus neoformans have been divided into two species C. neoformans and C. gattii, with Cryptococcus neoformans comprising serotypes A, D, and AD and C. gattii comprising serotypes B and C. Cryptococcus neoformans have also been subdivided into two varieties C. neoformans var. grubii, serotype A, and C. neoformans var. neoformans, serotype ...

The effects of two different harvest stages (full flowering and full podding) on forage yield and quality of ten forage rape (Brassica napus L. var. oleifera) and three turnip (Brassica rapa L. var. rapa) cultivars were evaluated under rainfed conditions in a Mediterranean type climate at Bursa, Turkey, during the 2002/2003 and 2003/2004 growing seasons. Plant height, branches per plant, leaf l...
