self-incompatibility in almond and prunus species is an important genetic trait that prevents self-fertilization. self-incompatibility in almond is controlled gametophytically by the multiallelic s-locus. this study was done in order to identification and preliminary selection of self-compatible progenies resulted from controlled crosses in almond using specific primer sff-sfr.some important mo...

Self-incompatibility in almond and Prunus species is an important trait that prevents self-fertilization. Selfincompatibility in almond is controlled gametophytically by the multiallelic S-locus. Present study was done in order to identification and preliminary selection of self compatible progenies resulted from controlled crosses in almond using specific primer SfF/SfR. Some important morphol...

self-incompatibility is one of the main problems in almond production. in this research work, at the first step, some local cultivars as well as some imported ones were evaluated from the point of their male and female organ compatibility. then, ten selected commercial self-incompatible cultivars(female parents) were crossed with two self-compatible cultivars(male parents) i. e. tuono and super...

The aims of this study were to isolate and identify of methicillin resistant Staphylococcus aureus (MRSA) from mastitic cow milk. The investigation presence of mecA genes and molecular characteristics of these isolates using eight primers of repetitive element palindromic-PCR (Rep-PCR) analysis were achieved. Ninety six milk samples, collected from clinical mastitic cows from Sharkia Governorat...

Self-incompatibility is one of the most important difficulties in almond production which reduce fruit set dramatically and makes orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. In this research identification and screening of 86 almond progenies obtained from selfing Touno after the self-pollination by PCR reaction with specific ...

In the gut tissues and contents of the earthworm Pheretima (Metaphire) hilgendorfi, cellulase activity which contributes to the terrestrial ecosystem nutrient cycling has been detected. The origin of the cellulase production, whether it is the earthworm itself or the microorganisms, has not been established at the molecular level. In our study, a cellulase [endo-β-1,4glucanase (EGase), EC3.2.1....

breeding of almond to attain self compatible cultivars is among the objectives followed in almond breeding. early identification of self-compatible genotypes from self-incompatible ones is very important in saving of time and expenses. there are different methods of either classical or molecular nature to recognize self-compatibility in genotypes. in this study, pcr-based method with specific p...

Cotton cultivar Coker has been already transformed with recombinant pBI121-chi via Agrobacterium tumefaciens. The T-DNA region of pBI121-chi carries the chitinase (chi ) gene from bean and is under the control of the CaMV35S promoter. T1 and T2 progenies of transgenic cotton containing the chi gene were used in this study.  Polymerase chain reaction (PCR), Southern and Western blotting data con...

Mutual relationship between endophytic fungi and some gramineuos plants is one of the recently known host-microbe interactions. Endophytic fungi are classified in class Ascomycetes, order Hypocreales, tribe Balansieae and mostly genus Neotyphodium. They are transferred into the progeny via maternal stock and have many benificial effects to their host plants, such as resistance to pests and dise...

Maize developed from its ancestor, teosinte, about 10,000 years ago. The evolution has gone teosinte with multiple tillers to single-tiller maize plants. An investigation took place identify and sequence genes related tillering ability in perform In silico analysis. Mating proceeded by manual pollination between the commercial hybrid SC2031 of (Zea mays L.) genotype Domiata (Durra rayyana). par...
