The Research Institute for Plant Genetic Resources is the national center global genetic resources of cultivated plants and their wild relatives, which are preserved in form collections status, represented by seeds, vegetative reproductive organs parts plants, herbarium specimens, as well plantations perennial crops. Collections numbering more than 43 thousand accessions concentrated here over ...

The European Search Catalogue for Plant Genetic Resources, EURISCO, provides information about 1.8 million crop plant accessions preserved by almost 400 institutes in Europe and beyond. EURISCO is being maintained on behalf of the European Cooperative Programme for Plant Genetic Resources. It is based on a network of National Inventories of 43 member countries and represents an important effort...

The first botanical gardens and collections of preserved plants in the 16 century served didactic purposes and should ensure correct identification of medicinal, ornamental and other useful plants. Collections of preserved plants were nearly all book-herbaria, emulating illustrated books and owned by individual botanists. Curiosity cabinets of nobles and prominent scholars were larger collectio...

Assessment of genetic diversity and individual relationships in rice (Oryza sativa) germplasm collections seems to be necessary for future rice breeding program. In order to understand genetic relationships of 30 rice genotypes, nine morphological traits, seven physicochemical properties and twelve RAPD primers were used for study of 30 rice genotypes. Among morphological traits, numbe...

During the previous decade, a new array of analytical methodologies and technologies were introduced related to the analysis of microbial, plant and animal metabolomes (complete collections of all low molecular weight compounds in a cell). The scientific field of metabolomics was born. In this review, we discuss advances in methodologies and technologies, and outline applications. a 2005 Elsevi...

Sampling methods for square and boll-feeding plant bugs (Hemiptera: Miridae) occurring on cotton, Gossypium hirsutum L., were compared with the intent to assess if one approach was viable for two species occurring from early-season squaring to late bloom in 25 fields located along the coastal cotton growing region of south Texas. Cotton fleaphopper, Pseudatomoscelis seriatus (Reuter), damages s...

Sooty mold fungi are often associated with honeydew which insects secrete while feeding on the plant. A great variety of these fungi occur in the North of Iran, especially on Citrus ssp which is one of the most widely cultivated fruit trees in this region. During last 10 years, several collections of these fungi examined and 15 species have been recorded. In this paper seven previously unreport...

One of the world's greatest plant collections has won a top heritage award at a time when it is highlighting with a tree-top walkway the need to study the forest canopy which is one of the most crucial but least understood habitats.

The Coppermine River in western Nunavut is one of Canada's great Arctic rivers, yet its vascular plant flora is poorly known. Here, we report the results of a floristic inventory of the lower Coppermine River valley and vicinity, including Kugluk (Bloody Falls) Territorial Park and the hamlet of Kugluktuk. The study area is approximately 1,200 km2, extending from the forest-tundra south of the ...
