Background: Dermatophytes create the most common fungal disease in humans, called dermatophytosis. The two species of Trichophyton rubrum and Trichophyton interdigital are responsible for over 80% of types of dermatophytosis. So far, several morphological and physiological methods have been used to differentiate these very similar species, but these methods are generally time-consuming and have...

Legumes host their Rhizobium spp. symbiont in novel root organs called nodules. Nodules originate from differentiated root cortical cells that dedifferentiate and subsequently form nodule primordia, a process controlled by cytokinin. A whole-genome duplication has occurred at the root of the legume Papilionoideae subfamily. We hypothesize that gene pairs originating from this duplication event ...

cell expansion and cell division are two main processes in plant growth and development. expansin proteins play a role key in cell expansion. these non-enzyme proteins involve in many growth and developmental processes. this protein affects drought tolerance. atexpb2 gene belongs to these proteins family. atexpb2 gene mainly expresses in the root tissue. in this study the expb2 gene, that was i...

A global map of gene expression within an organ can identify genes with coordinated expression in localized domains, thereby relating gene activity to cell fate and tissue specialization. Here, we present localization of expression of more than 22,000 genes in the Arabidopsis root. Gene expression was mapped to 15 different zones of the root that correspond to cell types and tissues at progress...

Our question answering system was built with a number of priorities in mind. First, we wanted to experiment with natural language processing (NLP) technologies such as shallow parsing, named entity tagging, and coreference chaining. We felt that the small number of terms in the questions coupled with the short length of the answers would make NLP technologies clearly beneficial, unlike previous...

Three closely related parthenogenetic species of root-knot nematodes, collectively termed the Meloidogyne incognita-group, are economically significant pathogens of diverse crop species. Remarkably, these asexual root-knot nematodes are capable of acquiring heritable changes in virulence even though they lack sexual reproduction and meiotic recombination. Characterization of a near isogenic pai...

Rhizobium Nod factors (NFs) are specific lipochitooligosaccharides that activate host legume signaling pathways essential for initiating the nitrogen-fixing symbiotic association. This study describes the characterization of cis-regulatory elements and trans-interacting factors that regulate NF-dependent and epidermis-specific gene transcription in Medicago truncatula. Detailed analysis of the ...

armillaria root and crown rot is an important disease of woody plants including fruit, forest and ornamental trees in different regions. the disease is common in isfahan and causes economical losses on a broad range of fruit trees. there only a few tolerant varieties to disease, and there is no efficient method in controlling the disease. therefore, detection of the pathogen from soil is necess...

The large size and complexity of the garden pea (Pisum sativum L.) genome hamper its sequencing and the discovery of pea gene resources. Although transcriptome sequencing provides extensive information about expressed genes, some tissue-specific transcripts can only be identified from particular organs under appropriate conditions. In this study, we performed RNA sequencing of polyadenylated tr...
