• Spring phenological traits of plant species in Northeast China are analyzed. plants phylogenetically conserved. Reproductive phenology is more conserved than vegetative phenology. Native climate has a stronger effect phylogeny on spring traits. The effects change have been widely recognized around the world. However, internal factors (such as phylogeny) variations among remains unclear. In th...

cucumber mosaic virus (cmv) belongs to the genus cucumovirus in the family bromoviridae. althaea officinalis, commonly known as hollyhocks in the family malvaceae, is an annual plant whose fruit, flower and root are used as medicinal products. in this study, five samples of hollyhocks leaves with viral symptoms were collected and cmv was detected using das-elisa from the samples. ta-alth isolat...

sixteen isolates of colletotrichum were collected from leaves with anthracnose symptoms or leaf spots of twelve wild, cultivated and ornamental plant species from the guilan, mazandaran, and golestan provinces in northern iran. five different species, including c. aenigma, c. gigasporum, c. godetiae, c. karstii, and c. musae were identified based on the dna sequence data (tub2, gs, gapdh). four...

colletotrichum species are associated with citrus plants as pathogens, saprobes and endophytes. according to the most recent multigene phylogenetic analysis, a lot of changes were happened in the taxonomy and species delimitation in the genus colletotrichum. in this investigation, 292 colletotrichum isolates were obtained from leaves, fruits and stems of citrus species at golestan, mazandaran, ...

infectious bronchitis virus (ibv) is a contagious pathogen in fowl that results in economic loss in the poultry industry. in this study, the amino acids sequences of three structural proteins m, n, and s1 for five iranian ibv isolated during 1998-2011 have been analyzed. conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by bioedit ve...

A taxonomic overview of the genus Anticharis (Scrophulariaceae) especially in Namibia and Angola is presented. Three new species are described, viz. A. namibensis B. Nord., A. kaokoensis B. Nord. and A. angolensis B. Nord. A key to the Anticharis species of Namibia and Angola is presented. Some aspects of phytogeography, molecular phylogeny and photosynthetic pathways (C3-C4) are briefly discus...

background: the sry gene (sry) provides instructions for making a transcription factor called the sex-determining region y protein. the sex-determining region y protein causes a fetus to develop as a male. in this study, sry of 15 spices included of human, chimpanzee, dog, pig, rat, cattle, buffalo, goat, sheep, horse, zebra, frog, urial, dolphin and killer whale were used for determine of bioi...

Arbuscular mycorrhizal fungi (AMF) are associated with almost all plants in nature and are ubiquitous. The arbuscular mycorrhizal fungi status of 10 wild herb and shrub was investigated during winter and summer season in Pine forest of himalaya(HP). The herbs and shrubs investigated for studied are: Reinwardtia indica, Berberis lycium, Viola serpens,Taraxacum officinale, Caryopteris wallichiana...
