Citrinin is a nephrotoxic mycotoxin produced by several species of the genus and Monascus. Citrinin is generally formed after harvest and occurs mainly in stored grains. efficacy of different concentrations of aqueous leaf extracts of Rhazya stricta Decne and Cleome amblyocarpa two fungal strains Penicillium notatum and Aspergillus niger and fungal biomass by the isolates was suppressed, depend...

The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF) and nitrogen-fixing bacteria (NFB). This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart.) Macbr., which belongs to the Piptadenia group. Two consecutive experiment...

In leaves of most C(4) plants, the biochemistry of photosynthesis is partitioned between mesophyll and bundle sheath cells. In addition, their cell biology and development also differs from that in C(3) plants. We have a poor understanding of the mechanisms that generate the cell-specific accumulation of proteins used in the C(4) pathway, and there are few genes that have been shown to be impor...

Characeae (Charophyceae, Charophyta) contains two tribes with six genera: tribe Chareae with four genera and tribe Nitelleae, which includes Tolypella and Nitella. This paper uses molecular and morphological data to elucidate the phylogeny of Tolypella species in North America. In the most comprehensive taxonomic treatment of Characeae, 16 Tolypella species worldwide were subsumed into two spec...

The dynamics of mesophilic and thermophilic bacterial population was studied in the bulk soil and rhizosphere of the grass Aristida adscensionis L. in a caatinga of the semi-arid Brazilian Northeast. Mesophilic heterotrophic bacteria, spore–forming bacteria and actinomycetes were significantly more abundant than thermophiles, and their counts were 10 10 CFU g dry soil, showing weak fluctuations...

Riparian phreatophytes in hyperarid areas face selection pressure from limiting groundwater availability and high transpiration demand. We examined whole-plant water use hydraulic traits Populus euphratica Tamarix ramosissima seedlings to understand how they adapt variations. These species coexist the Tarim River floodplain of western China. Measurements were performed on 3-year-old grown lysim...

Bu çalışmanın amacı, Stenocephalae seksiyonuna dâhil olan Cousinia davisiana, C. foliosa, ramosissima ve stenocephala türlerinin hipoglisemik antimikrobiyal etkisinin incelenmesidir. Çalışma kapsamında bitkilerin toprak üstü kısmı toplandıktan sonra metanol ile oda sıcaklığında maserasyon yöntemiyle ekstreleri hazırlanmış bu ekstrelerin α-amilaz, α-glikozidaz inhibitör etkisi tayin edilmiştir. ...

Salicornia species are halophyte plants that an important source for food, pharmacy, and bioenergy. They can be consumed as a leafy vegetable, but they accumulate heavy metals carry health risk when knowledge of how each behaves in different types soil is lacking. This present work aimed to determine what extent S. ramosissima cultivated food estuaries contaminated by it used phytoremediation w...
