citrullus ecirrhosus/nicotine

The present study examines the possible ameliorative effects of the hydromethanolic extract of Citrullus lanatus rind (HECL) on some reproductive function and oxidative indices of the testes in male Wistar rats following administration of nicotine. Twenty male rats were assigned into four groups:

In 1989, a wilt and stem rot of muskmelon (Cucumis melo L.) was reported on seedlings grown under plastic in northern Serbia (1). In 1998, a similar disease of watermelon (Citrullus vulgaris L.) transplants occurred in central Serbia, resulting in losses estimated at 20% of plants grown in the

Fatty acid hydroperoxide lyase (HL) is the key enzyme for the production of the "green note"compounds, leaf aldehyde [(2E)-hexenal] and leaf alcohol [(3Z)-hexenol], in plant tissues. A cDNA encoding HL was cloned from leaves of watermelon (Citrullus lanatus) and expressed in Nicotiana tabacum. The

Papaya ringspot virus (PRSV, genus Potyvirus, family Potyviridae) is economically important due to its worldwide distribution and because it can cause serious losses in both cucurbit crops and papaya (3). PRSV has been previously reported from cucurbit crops in Iran (2). In Khuzestan Province,

BACKGROUND Mitogen-activated protein kinase (MAPK) cascades, which consist of three functionally associated protein kinases, namely MEKKs, MKKs and MPKs, are universal signaling modules in all eukaryotes and have been shown to play critical roles in many physiological and biochemical processes in

The advances in molecular genetics and biotechnology in the field of medicinal plant research are discussed with focusing on the works using transgenic plants. Differentiated organ cultures and transgenic teratomas, incited by the infection with mutants of Agrobacterium Ti and Ri plasmids, were

Cucumber green mottle mosaic virus (CGMMV) was first discovered in 2003 in China (2) and developed an epidemic during 2005 (1). To know the occurrence scale and damage level of CGMMV, a survey was carried out in the main areas of cucurbitaceous plant production and seed trading in 2006 and 2007 in

Plant cells are endowed with an aphidicolin inactivating activity. Data on cultured cells show that the rate of inactivation depends on the cell type, Daucus carota cells being the most effective among the other tested materials (Oryza sativa and Nicotiana plumbaginifolia). Also germinating seedling
