Identification of Self- incompatibility Alleles in Some Almond Genotypes by Degenerate S-RNase Primers
The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...
متن کاملCompatible Pollinations in Solanum chacoense Decrease Both S-RNase and S-RNase mRNA
Gametophytic self-incompatibility (GSI) allows plants to block fertilization by haploid pollen whose S-allele constitution matches one of the two S-alleles in the diploid styles. GSI in Solanum chacoense requires a stylar S-RNase, first secreted from cells of the transmitting tract then imported into incompatible (self) pollen tubes. However, the molecular mechanisms allowing compatible pollen ...
متن کاملPolyacrylamide gel electrophoresis of S-RNase fragments for identification of S-genotypes of Japanese pear (Pyrus pyrifolia)
Japanese pear (Pyrus pyrifolia) exhibits gametophytic self-incompatibility (GSI) controlled by a complex and multiallelic S locus. The pistil-part product of the S locus is the polymorphic ribonuclease, S-RNase. Information on S-genotypes is important for the production and breeding of Japanese pears. Molecular analyses of S-genotypes of Japanese pear have been conducted with the CAPS (cleaved ...
متن کاملDetermination of Reservoir(s) and Vector(s) of Cutaneous Leishmaniasis by Nested-PCR in Marvdasht District, Fars Province, Southern Iran
Introduction: Cutaneous leishmaniasis (CL) is an increasing public health problem in several parts of Iran. In southern parts, the incidence of CL has been doubled over the last decade. This epidemiological study was done for determination of reservoir(s) and vector(s) of cutaneous leishmaniasis in rural regions of Marvdasht, Fars province,southern Iran during 2003 and 2004. Methods: A total of...
متن کاملAnalysis of Romance in Beighami\'s Darabnameh
For centuries, storytellers and scops recited epics and national, tribal, historical, and religious stories for people, through musical speeches. Some of these narrators wrote down what they recited, and some others dictated them for scribes to be recorded. Some kings and lords also had scops in their courts to recite the stories to scribes. One of the old, oral stories of Persian literature th...
