An investigation of the phenotypic characteristics 19 rhizobial strains, isolated from root nodules different plant legumes grown in soil agriculture farms Ismailia governorate, transpired. Most isolates were creamy or white opaque, mucoid, with a convex elevation, translucent, and smooth margined. Microscopic revealed that all bacterial rod-shaped had no positive affinity for Gram-stain. Ident...

For the first time, genetic variability and differentiation among Ten Synconium white butterfly populations originating from tissue cultured plants maintained in pro-trays under the poly house & green house conditions in Indo American hybrid Seed Company, Bangalore were examined. Random Amplified Polymorphic DNA (RAPD) marker data were obtained and analysed with respect to genetic diversity. Th...

Bambusa balcooa Roxb. was in vitro propagated by optimizing protocol using nodal segment from secondary branches with 100% success MS liquid media containing 100 mg/l Myo-inositol, 3% sucrose supplement 4.4 - 26.64 ?M BAP for shoot multiplication, and 2.69 32.26 NAA root induction. The highest multiplication (14.53 ± 0.33 folds), length (5.9 0.6 cm), number per explants (4.0 0.24), rooting (89....

This study was accomplished to detect variation generated through eposure of fenugreek (trigonella foenum-graecum L.) seeds seven gamma irradiation doses (0,25,50,100,150,300 and 400) GY by using twenty RAPDs primers as molecular marker ,results indicated that OPA-14 ,OPC-19 OPH-01success in giving five treatments a unique fingerprint. Molecular size amplicon ranged between 2913 bp produced pri...

The Honey bee is an important model animal for behavioral study as it is a colonial insect with complex social behavior. Many studies have characterized its fascinating behavioral repatriate, but little is known about the genetic basis of its behavior because of difficulties in maintaining selected stocks and the scarify of genetic markers. However, it is now possible to construct detailed link...

Native diversity is well represented in northern and eastern parts of India for mango. We evaluated three important polymerase chain reaction (PCR) based marker techniques viz., random amplified polymorphic DNA (RAPD), inter simple sequence repeat (ISSR) and directed amplified mini satellite DNA (DAMD) and examined their suitability for depicting genetic relationships and discrimination among c...

Givotia rottleriformis Griff. is an economically important dioecious tree species known for the softwood used in making toys. Knowledge of genetic variation in a dioecious tree species is important for devising strategies for its successful management and conservation. Studies were conducted to examine the genetic variation in Givotia plants using RAPD (random amplified polymorphic DNA) analysi...

Two Vietnamese rice mutants (M2-2 and M2-4 second generation line 2 and line 4 respectively), induced by gamma irradiation were examined and compared to their parent (TT), and the Australian cultivar Amaroo (Am) for salt tolerance and genomic differences. Seedlings in tissue culture provided high yields and good quality DNA, especially with young shoots. Changes in DNA of the mutants in compari...
