Unlike modern cultivars selected for their growth performances in specific environmental conditions, local landraces have a high genetic variability that is an important resource for plant breeding. Consequent to their high adaptation to different environmental conditions, these landraces may have evolved adaptive gene complexes To promote the survival of endangered lentil landraces, we previou...

Esau sold his birthright to Jacob for a mess of red pottage, a dish thought to be the red lentil (Lens culinaris Medik.). Taking today's price of US $800 per tonne, this particular pulse must seem to be an attractive crop to many farmers. Unfortunately, red lentils are a rather poor yielding crop, so in the late 1980's when it was noted in Australia that the pinkish cotyledons of the “blanche f...

Excised Pisum sativum L. root tips were incubated in a pH 5.2 sucrose medium containing abscisic acid. Elongation growth was inhibited by 100 mum abscisic acid. However, decreasing the abscisic acid concentration caused stimulation of elongation, the maximum response (25% to 30%) occurring at 1 mum abscisic acid. Prior to two hours, stimulation of elongation by 1 mum abscisic acid was not detec...

Lectins extracted from corn (Zea mays L.) kernel with Tris-HCl buffer pH 7.5 were isolated from the crude extract by affinity chromatography on Sepharose 6B-N-acetyl-d-galactosamine and Sepharose 6B-methylalpha-d-mannoside, and also by lectin affinity chromatography using concanavalin A and Lens culinaris lectin as ligands. According to preferential monosaccharide specificity, salt-soluble lect...

Samples of the root nodules were collected to isolate different species genus Rhizobium from several leguminous plants; Trigonella foenum-graecum, Medicago sativa, Lens culinaris, Vigna mungo, Vicia faba, Phaseolus vulgaris, and Cicer arietinum, based on their morphological, cultural, biochemical characteristics, in addition identification each at level by amplified polymerase chain reaction (P...

This study surveyed a rapid, efficient and reproducible protocol for in vitro shoot regeneration and rooting by different explants and different concentration of BAP. Due to optimization of shoot regeneration, two media including of MS and modified MS (MS salts with double concentration of CaC21, and B5 vitamins), different explants such as decapitated embryo axes, epicotyls and cotyledonary no...
