the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower. therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...
During hindbrain development, facial branchiomotor neurons (FBM neurons) migrate from medial rhombomere (r) 4 to lateral r6. In zebrafish, mutations in planar cell polarity genes celsr2 and frizzled3a block caudal migration of FBM neurons. Here, we investigated the role of cadherins Celsr1-3, and Fzd3 in FBM neuron migration in mice. In Celsr1 mutants (knock-out and Crash alleles), caudal migra...
With the objective to identify previously unknown parental relationships among grapevine cultivars, 352 cultivars of Vitis vinifera L. were analyzed at 17 microsatellite loci. 29 were found to be duplicate genotypes of other cultivars. From the 323 unique genotypes, 89 possible pairs of parents were identified for 52 cultivars (i.e., each putative progeny cultivar shared at least one allele wit...
Abstract Short vase life and low quality of cut rose flowers are the main problems of most rose greenhouses in Iran. Calcium is one of the most important nutrients that plays a major role in vase life of cut rose flowers. In this study, a factorial experiment was conducted based on completely randomized blocks design to elucidate the effects of foliar application of calcium rates and sources o...
Ethylene plays an important role in wide-ranging aspects of plant growth and development, includingfruit ripening, leaf and flower senescence. In this study, the expression patterns of two genes involved in theethylene signal transduction pathway (RhCTR1 and RhCTR2) were investigated during the flower openingstages in two Rosa hybrida cultivars, ‘Black magic’ and ‘Maroussia’, ...
We used native polyacrylamide gel electrophoresis to identify polymorphism levels in α- and β-esterase loci from leaf tissues of Brazilian soybean cultivars for the analysis of population genetic diversity and structure, and to investigate relationships between conventional and genetically modified cultivars. The cultivars included lines developed by a soybean-grower cooperative (CD), by ...
Acytogenetic study was performed on 66 tetraploid cotton cultivars (Gossypium hirsutum L.) and their hybrids. The cultivars studied differed significantly in their chiasma frequency and distribution as well as chromosome pairing indicating their genetic differences. Adjacent and alternate quadrivalents were formed in most of the cultivars. A-A or D-D heterozygote translocations occurred in most...
A replicated field study was conducted from 1972 to 1980 involving soybeans grown in 2-, 3-, and 4-year rotations with maize in soil infested with Meloidogyne incognita. Monocultured soybeans were maintained as controls. Cropping regimes involved root-knot nematode susceptible and resistant soybean cultivars and soybeans treated and not treated with nematicides. Yields of susceptible cultivars ...
