In the present study, six species of Bipolaris viz. B. heveae, B. neergaardii, B. papendrofii, B. zeae, B. oryzae, and B. australiensis and two species of Curvularia viz. C. intermedia and C. heteropogonicola were identified on graminicolous species. Bipolaris heveae on Echinochloa sp., Cynodon dactylon and Arundo sp., B. neergaardii on Oryza sativa, B. papendrofii on Saccharum officinarum and ...

From the bulbils of Dioscorea bulbifera L. var sativa, two clerodane diterpenoids, Bafoudiosbulbins F (1) and G (2), together with five known compounds: Bafoudiosbulbins A–C, 3,5,40-trihydroxy-30-methoxybibenzyl, and kaempferol were isolated. Their structures were established by spectroscopic techniques, Y, COSY he basi as revis

Cannabis sativa L. is one of the oldest plants known in medicine and one that has been most studied with respect to its phytochemistry (Turner et al., 1980). Currently, a total of 483 constituents have been identified in cannabis of which 66 are cannabinoids (Ross et al., 1995). About 20 flavonoids have been reported to be present in the cannabis plant as aglycones or as conjugated O-glycosides...

Various beneficial properties has been attributed to Nigella sativa, including its antioxidant potential. Previously, it was reported that supercritical fluid extraction (SFE) could be used to obtain N. sativa extract rich in antioxidants. In the present study, N. sativa extracts prepared using the previously optimized SFE as well as the traditional Soxhlet extraction approaches were analyzed f...

The genus Avena comprises four distinct genomes organized in diploid (AA or CC), tetraploid (AABB or AACC) and hexaploid species (AACCDD), constituting an interesting model for phylogenetic analysis. The aim of this work was to characterize 45S rDNA intergenic spacer (IGS) variability in distinct species representative of Avena genome diversity-A. strigosa (AA), A. ventricosa (CvCv), A. erianth...

In this work 13 populations of the leafhopper species Alebra albostriella (Fallén, 1826) (6 populations) and A. wahlbergi (Boheman, 1845) (7 populations) (Cicadellidae: Typhlocybinae) from Greece were studied cytogenetically. We examined chromosomal complements and meiosis in 41 males of A. albostriella sampled from Castanea sativa, Fagus sylvatica and Quercus cerris and in 21 males of A. wahlb...

Camelina sativa is an annual oilseed crop that is under intensive development for renewable resources of biofuels and industrial oils. MicroRNAs, or miRNAs, are endogenously encoded small RNAs that play key roles in diverse plant biological processes. Here, we conducted deep sequencing on small RNA libraries prepared from camelina leaves, flower buds and two stages of developing seeds correspon...

Nitrogen (N)-fixing Acacia species are often aggressive invaders outside their native range. When invading riparian temperate forests, they can decrease tree diversity, alter the quality of litter inputs to streams and increase water N concentration. Although effects diversity nutrient enrichment on decomposition associated microbial decomposers have been widely studied, individual combined rem...

A satellite DNA sequence, As120a, specific to the A-genome chromosomes in the hexaploid oat, Avena sativa L., was isolated by subcloning a fragment with internal tandem repeats from a plasmid, pAs120, that had been obtained from an Avena strigosa (As genome) genomic library. Southern and in situ hybridization showed that sequences with homology to sequences within pAs120 were dispersed througho...

The use of naturally-occurring agents to regulate tumorigenesis is on the rise. Several herbal extracts, pure plant-derived active constituents, and food additives have been reported to possess potent anti-cancer properties and cancer-ameliorating effects. The wide-range anti-cancer effects of Nigella sativa, also known as black seed or black cumin, have been extensively studied using different...
