implications of zinc fertilization for ameliorating toxicity (neurotoxin) in grasspea (lathyrus sativus)

Genetic diversity among induced mutants of grasspea (Lathyrus sativus L.)

Introduction Knowledge about genetic diversity is a prerequisite of any breeding programme. Inclusion of diverse parents in hybridisation programmes serves the purpose of combining desirable genes in new recombinations. Mahalanobi’s D statistic (7) is a powerful tool in quantifying the degree of divergence at genotypic level. Several workers have used this method to quantify the degree of diver...

Excitotoxicity of lathyrus sativus neurotoxin in leech retzius neurons.

The effects of Lathyrus sativus neurotoxin were studied on the cell membrane potential and cellular cation composition in Retzius nerve cells of the leech Haemopis sanguisuga, with ion-selective microelectrodes using liquid ion-exchangers. Bath application of 10(-4) mol/l Lathyrus sativus neurotoxin for 3 min depolarized the cell membrane potential and decreased the input resistance of directly...

Mutagenesis as a tool for improvement of traits in grasspea (Lathyrus sativus L.)

Introduction Grasspea (Lathyrus sativus L.) is produced as major crop in Bangladesh, China, India and Pakistan, and to a lesser extent in many countries of Europe, the Middle East, northern Africa, as well as in South America. It is extensively cultivated and naturalised in the Middle East countries of Iraq, Iran, Afghanistan, Syria and Lebanon and in Ethiopia, Egypt, Morocco, Algeria and Libya...

Possible mechanism of action of neurotoxin from Lathyrus sativus.

Evaluation of selected traits in grasspea ( Lathyrus sativus L . ) genetic resources

Introduction Grass pea (Lathyrus sativus L.) is one of the most important species of the Lathyrus genus. It has two subspecies : spp. asiaticus Zalk., which has small, coloured seeds, occurring mainly in the continental part of Asia and Africa and spp. europaeus Zalk. with large seeds, occurring predominantly in Central Europe and European Russia. According to Vavilov (8) its genetic centre is ...

Analysis of genetic diversity among selected grasspea (Lathyrus sativus L.) genotypes using RAPD markers.

Randomly amplified polymorphic DNA (RAPD) technique was applied to assess the genetic variability among five selected genotypes of grasspea. Out of 30 random decamer primers tested for the present investigation 20 showed reproducible DNA amplification. A total of 257 loci were amplified of which 159 were polymorphic including 57 genotype-specific unique bands. Amplicons had molecular weights ra...
