Stereum hirsutum is a white-rot fungus which produces laccase and manganese peroxidase as part of its ligninolytic system. Maximal ligninases production (under the conditions studied) was obtained in the media containing 250 microM Cu++ along with a pH value of 5.5. The fitting of ligninase production to a linear equation showed negative interaction between increasing values of pH and concentra...

Alternate-1 and alternate-2 orientation of chromosomes, as well as the two types of adjacent orientation, were observed cytologically in the ring configurations of three reciprocal translocation heterozygotes of Gossypium hirsutum L. The observations indicate that the two types of alternate orientation should be characteristic of ring-forming translocations.

Opportunities to directly study infrequent forest disturbance events often lead to valuable information about vegetation dynamics. In mesic temperate forests of North America, stand-replacing crown fire occurs infrequently, with a return interval of 2000-3000 years. Rare chance events, however, may have profound impacts on the developmental trajectories of forest ecosystems. For example, it has...

Gossypiumbarbadense is a cultivated cotton species and possesses many desirable traits, including high fiber quality and resistance to pathogens, especially Verticilliumdahliae (a devastating pathogen of Gossypium hirsutum, the main cultivated species). These elite traits are difficult to be introduced into G. hirsutum through classical breeding methods. In addition, genetic transformation of G...

Allelopathic plants are important resources for the discovery of bioherbicides. Rosebay willowherb [Chamaenerion angustifolium (L.) Scop. syn. Epilobium L.] widely distributes in Western Asia, Europe, and North America, behaves as a dominant species within community due to production substances that restrict growth other plants. This study aims at investigating allelopathic potential rosebay by...

Background: Gossypium arboreum is resistant to Cotton leaf curl Burewala virus and its cognate Cotton leaf curl Multan betasatellite (CLCuBuV and CLCuMB). However, the G. arboreum wax deficient mutant (GaWM3) is susceptible to CLCuV. Therefore, epicuticular wax was characterized both quantitatively and qualitatively for its role as physical barrier against whitefly mediated viral transmission a...

In this study, six taxa of micromycetous fungi collected from Golestan province (N Iran) during spring and summer of 2010, are reported. Melanospora zobelii on Picoa lefebvrei, Diachea leucopodia on Sambucus nigra, Choanephora cucurbitarum on Brassica oleracea, Trichurus spiralis on Prunus domestica, tuber of Solanum tuberosum and seeds of Gossypium hirsutum and Dictyosporium heptasporum on dea...

The supplementary botanical list features 64 species of vascular plants which are new, rare or forgotten records from the Faroe Islands. They cumulative notes produced numerous excursions over two last decades. new described with who discovered them, and literature references given where appropriate. Some not discoveries for Faroes but have been found in localities missed most recent lists. als...

Polyamines have been associated with a large number of plant growth and developmental processes. In particular, they have been associated with floral initiation with increased polyamines concentration occurring during flowering in horticulture plants. However, there is limited information about polyamines in cotton (Gossypium hirsutum L.) and how they are distributed in the cotton plant. In add...
