onion is one of the important strategic crop plants of a highly valuable nutritional food source, consumed almost around the whole world. thus, the genetically oriented studies around the plant are valuable and inevitable. for a following of these studies, some onion masses from various regions throughout iran, including: kashan-white, azarshahr-red, isfahan-dorcheh, ghom-white, zanjan-gholighe...

this experiment was performed based on split plot in rcbd with three replications in minab agricultural research station during two successive years. main plots were allocated to planting method (basin and furrow) and sub plot to four onion cultivars (‘primavera’, ‘white early grano 502’, ‘ht3544’ and ‘ht3560’). nursering was done in october and the transplants were transferred to main land in ...

This study was carried out to determine the resistance levels of some onion genotypes in Yalova gene pool by Fusarium testing during seedling stage. The isolate used oxysporum f. sp. cepae, which causes damping off stage and later basal rot bulbs. variance analysis for test mean differences against control were analyzed using General Linear Model Tukey test. germination rate seeds varied betwee...

Rho-binding kinase and myosin phosphatase regulate the contraction of actomyosin filaments in non-muscle and smooth muscle cells. Previously, we described the role of C. elegans genes encoding Rho-binding kinase (let-502) and myosin phosphatase targeting subunit (mel-11) in epidermal cell-shape changes that drive morphogenesis and in spermathecal contraction. Here we analyze their roles in a th...

Cell shape changes are crucial for metazoan development. During Caenorhabditis elegans embryogenesis, epidermal cell shape changes transform ovoid embryos into vermiform larvae. This process is divided into two phases: early and late elongation. Early elongation involves the contraction of filamentous actin bundles by phosphorylated non-muscle myosin in a subset of epidermal (hypodermal) cells....

one of the growth limiting factors of onion plants is root and basal plate rot disease, caused by fusarium oxysporum f. sp. cepae. in this research, eight iranian onion genotypes, azarshahr red, ghom white, herssin, isfahan dorcheh, kashan white, nishabour ishaghabad, yazd abarkoh, zanjan gholigheseh and two commercial genotypes, texas erly grano and yellow sweet spanish were investigated. geno...

let-502 rho-binding kinase and mel-11 myosin phosphatase regulate Caenorhabditis elegans embryonic morphogenesis. Genetic analysis presented here establishes the following modes of let-502 action: (i) loss of only maternal let-502 results in abnormal early cleavages, (ii) loss of both zygotic and maternal let-502 causes elongation defects, and (iii) loss of only zygotic let-502 results in steri...
