Socioeconomic Inequality in Fruit and Vegetable Consumptions in Elderly People: A Cross Sectional Study in North West of Iran

Molecular and Biochemical Evaluation of Ethyl Methanesulfonate-Induced Mutant Lines in Camelina sativa L

Background

Camelina sativa is one of the most important oilseeds that has a proportionate profile of essential unsaturated fatty acids that are suitable for human nutrition. In this regard, we can mention a high percentage and a reasonable ratio of omega 3 and omega 6.

Objectives

In the current study, the created variation of second-generation mutant (M2) camelina lines in terms of fatty acid profiles and ISSR molecular markers in C. sativa was evaluated.

Materials and Methods

For this purpose, while producing the first-generation of mutant plants (M1), 200 M2 seeds with 0.1% and 0.5% ethyl methanesulfonate (EMS) mutations were treated in two replications for 8 and 16 hours based on a completely randomized design.

Results

The results of mean comparisons showed that there was no significant difference between treatments in terms of fatty acids of palmitic acid, stearic acid, linoleic acid, eicosadienoic acid, oleic acid and erucic acid. The cluster analysis revealed that all the treatments used with five replications were divided into eight groups. It was found that all replications of the treatment with a concentration of 0.1% and a time of 16 hours (C1T2) were in the second group with the lowest palmitic acid was present among other treatments. Therefore, C1T2 treatment is recommended as the best treatment to reduce palmitic acid. Examination of the information content of ISSR molecular markers also showed that markers 2, 5, and 6 were the best informative markers in the detection of camelina fatty acid profiles.

Conclusion

A significant variation has been created in the fatty acids profile and it can be applied in future breeding programs depending on the intended purpose.
