Sixty isolates of Pythium aphanidermatum as the causal agent of sugar beet root rot were selected on the basis of their geographical origins, morphological and genetic diversity studies. Pathogenicity test using the Kruskal-Wallis analysis showed significant differences between the pathogenic potential of isolates. Based on the growth rate, isolates were categorized in two groups with low and h...

Thyme is an important medicinal plant in cosmetic, pharmaceutical and food industries. The first step for breeding of thyme is evaluating of genetic variation and relationship between thyme’s accessions. Therefore, the objective of this study was to evaluate morphology, chemical and molecular variation of 13 accessions of Thyme medicinal plant. ANOVA showed significant differences between acces...

Historical background Rheumatologists have long known that the common chronic arthropathies of childhood have both similarities and differences from adult-onset rheumatoid arthritis (RA), although it is also recognized that a few patients with typical RA will present in childhood. Arthritis in children is more heterogeneous than RA, and just as in RA, the pathological basis for juvenile arthrit...

Group II introns encode highly structured, frequently self-splicing RNAs; they are also mobile genetic elements. This mobility has been found to involve DNA-primed reverse transcription, with similarities to retrotransposition and telomere maintenance.

Recent work has revealed striking similarities in the genetic mechanisms underpinning somitogenesis in zebrafish and segmentation in the spider. Could this mean that the bilaterian common ancestor was segmented after all?

garlic (allium sativum .l) has been and is clonally propagated, because it does not produce seed under standard conditions. knowledge of plant recourses genetic diversity can be a first and most important step in achieving breeding program purposes. because of its high accuracy and reproducibility among different genetic diversity assessment techniques amplified fragment length polymorphism (af...

Similarities between the three related "PCI" complexes--eIF3, the COP9 signalosome and the proteasome lid--have hinted at novel pathways controlling protein homeostasis. Recent experiments with fission yeast have begun to weigh in with genetic evidence.
