Genetic diversity of Iranian melon cultigens revealed by AFLP markers
Iran is a part of the secondary centre of origin of melons, and therefore, there is a wealth of genetic variation of these species in this country. The Amplified Fragment Length Polymorphism (AFLP) marker was applied to investigate the genetic variations among five major Iranian melon cultigens (Cucumis melo) and ‘Ananasi’ as a general well-known cultivar. Ten primer pairs were used on 90 indiv...
متن کاملGenetic Control of Water and Nitrate Capture and Their Use Efficiency in Lettuce (Lactuca sativa L.)
Robustness in lettuce, defined as the ability to produce stable yields across a wide range of environments, may be associated with below-ground traits such as water and nitrate capture. In lettuce, research on the role of root traits in resource acquisition has been rather limited. Exploring genetic variation for such traits and shoot performance in lettuce across environments can contribute to...
متن کاملgenetic diversity of aegilops triuncialis l. accessions of iran revealed by microsatellite markers
in order to study the genetic diversity among 35 accessions of ae. triuncialis l. from17 ssr loci of 56 primer pairs originated from a and d genomes of bread wheat were used. seventy one fragments amplified totally and 68 of them were polymorph between genotypes. allele number ranged from 1 to 8 with average 4.18 per locus. pic value of markers was from 0.593 (xgwm-30-2d, xgwm-383-3d, xgwm-654-...
متن کاملInduction of Light Sensitive Dormancy in Seed of Lactuca sativa L. (Lettuce) by Patulin.
The antibiotic patiilin (I) has been reported to inhibit seed germination becauise of its toxicity (7). We considered that this butenolide (I) might induce light sensitive dormancy in seeds of lettuce because of its structural similarity to coumarin (II) and ramulosin (III), (see fig 1), which have been demonstrated to possess this biological activity (2,5,6). Possible activitv was tested in th...
متن کاملAgrobacterium-mediated transformation of cotyledonary leaf of lettuce (Lactuca sativa L.) by the GCHI gene
Lactuca sativa is widely used as a leafy vegetable belonging to the Asteraceae family. Cotyledonary leaves of in vitro lettuce seedlings were transformed by plasmids containing the GCHI gene. Also the effects of number of days of pre-cultivation and co-cultivation of explants were examined on the transformation frequency. After co-cultivation, the explants were transferred onto the regeneration...
