Seed fatty acid compositions and chemotaxonomy of wild safflower(Carthamus L., Asteraceae) species in Turkey

Abstract

Safflower is an important oilseed crop for the dry regions of the world. In the present study, we aimed to find out the seed oil content and composition of the wild relatives of safflower. For this purpose, 71 populations from 5 naturally growing Carthamus species were collected from Turkey: Carthamus dentatus (30 accessions), Carthamus lanatus (30 accessions), Carthamus persicus (2 accessions), Carthamus glaucus (6 accessions), and Carthamus tenuis (3 accessions). Our research covered all naturally growing safflower species in the flora of Turkey. The seeds belonging to 71 accessions were germinated in cabinets and transferred to vials in order to obtain seedlings and then sown in the field manually. After harvesting, the seed oil content (%) and fatty acid compositions were determined. The seed oil content ranged between 10.50% and 20.40% in all accessions. Thirteen fatty acids, mainly linoleic (58.8% to 82.6%), oleic (7.3% to 22.8%), and palmitic acids (4.8% to 8.8%) were determined. The fatty acid compositions were more or less similar in all investigated species; however, the seed oil contents were different. For the evaluation of fatty acid properties as a taxonomic character, cluster analysis was performed. The dendrogram based on the fatty acid ratios discriminated section Carthamus and section Atractylis of the genus Carthamus; however, the resulting tree was not compatible with the previously constructed phylogeny trees in detail.

MicroRNA expression patterns unveil differential expression of conserved miRNAs and target genes against abiotic stress in safflower

“…Safflower (Carthamus tinctorius L.) is one of the most desirable oilseed crops with remarkable yields (about 32-40% seed oil) [1], and can tolerate environmental stresses, including high temperatures, salinity, and dehydration. This oilseed crop has the ability to grow in most regions of the world, particularlywhere climatic and soil limitations prevent the cultivation of PLOS ONE | https://doi.org/10.1371/journal.pone.0228850 February 18, 2020 1 / 18 a1111111111 a1111111111 a1111111111 a1111111111 a1111111111…”

The Use of Wild Relatives of Safflower to Increase Genetic Diversity for Fatty Acid Composition and Drought Tolerance

“…The former is mainly used as an industrial oil for biodiesel and other biofuels (Meka et al, 2007) or application in chilled foods (Weiss, 1971), and the latter is used in cooking, salad dressing, and margarine (Meka et al, 2007). Wild species of Carthamus have high linoleic acid content ranging from 58.8 to 82% and low oleic acid content ranging from 7.3 to 22.8% (Sabzalian et al, 2008; Nazari et al, 2017; Arslan and Hacioglu, 2018). Variability for fatty acid profile in cultivated safflower affected by drought and salt stresses has been reported (Bagheri et al, 2012; Yeilaghi et al, 2012).…”

Fatty acids in wild hemp seeds (Cannabis sativa L. ssp. sativa var. spontanea Vavilov)

“…Poznavanje sastava masnih kiselina u lipidima semena može imati višestruki značaj. Više istraživača potvrdilo je da ovi podaci imaju hemotaksonomski značaj, odnosno mogu se koristiti kao taksonomski markeri pri determinaciji viših biljaka (Bağci et al, 2003;Arslan & Tarıkahya Hacıoğlu, 2018). Osim toga, sastav masnih kiselina u semenu može uticati na mnoge aspekte biologije semena, poput energije klijanja, životne sposobnosti i dugovečnosti semena, brzine klijanja i rasta klijanaca (Levin, 1974;Linder, 2000).…”
