“…Leaf water and osmotic potential decreased under salinity stress, but they were less affected in the salt-tolerant ecotypes than the sensitive ecotypes in safflower (Gadallah 1996;Gadallah and Ramadan 1997;Hameed and Ashraf 2008;Yermanos et al 1964). Under stress, osmotic potential of the soil solution become low and the seed germination will be inhibited due to difficulty in water absorption by seeds and casing sodium toxicity to embryo under alteration (Hasegawa et al 2000;Farsiani and Ghobadi 2009).…”

“…Safflower cultivation constitutes a more profitable crop for the farmers in some countries, compared to other conventional crops such as barley, lentil, and chickpea (Dajue and Mundel 1996;Yau 2004). The fact that safflower can overcome environmental stresses such as extreme temperatures, drought, and salinity has facilitated its expansion in areas around the world, where soil and climatic restrictions have impeded the cultivation of conventional food and cash crops (Yermanos et al 1964;Weiss 2000). In particular, safflower has demonstrated drought resistance with a slight decrease in crop yield and significant stability in water use efficiency (Lovelli et al 2007).…”

Safflower is one of the oldest cultivated crops, usually grown at a small scale. Safflower is grown for flowers used for coloring, flavoring foods, dyes, medicinal properties, and livestock feed. Safflower is underutilized but gaining attention due to oil yield potential and the ability to grow under high temperatures, drought, and salinity. Salinity and drought have negative effects by disrupting the ionic and osmotic equilibrium of the plant cells. The stress signal is perceived by membranes then transduced in the cell to switch on the stress responsive genes. This review discusses on stress tolerance mechanisms in safflower. Strategies are proposed for enhancing drought and salt resistance in safflower.

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

Environmental stresses influence the growth and development of plants by influencing patterns of gene expression. Different regulators control gene expression, including transcription factors (TFs) and microRNAs. MicroRNAs (miRNAs:~21 nucleotides long) are encoded by miRNA genes transcribed by RNA polymerase II (RNP-II) and play key roles in plant development and physiology. There is little knowledge currently available on miRNAs and their function in response to environmental stresses in safflower. To obtain more information on safflower miRNAs, we initially used a comparative genomics approach and succeeded in identifying 126 miRNAs belonging to 29 conserved families, along with their target genes. In this study, we investigated the expression profiles of seven conserved miR-NAs related to drought, salinity, heat, and Cd stress in the leaf and root organs using qRT-PCR, for the first time. Gene Ontology (GO) analysis found that target genes of miRNAs are often TFs such as AP2/ERF and HD-ZIP as well as NAC domain-containing proteins. Expression analyses confirmed that miRNAs can play a vital role in keeping safflower stress-tolerant. Differential expression of miR156, miR162, miR164, miR166, miR172, miR398, and miR408 regulate the expression of their respective target genes. These genes activate several pathways leading to physiological and biochemical responses to abiotic stresses. Some conserved miRNAs were regulated by abiotic stresses. Our finding provides valuable information to understand miRNAs in relation to different abiotic stresses in safflower.

“…Yield components such as seed yield, biomass yield (dry weight), number of plant per hectare, 1000‐seed weight, plant height, number of capitula per plant and capitula weight per plant were significantly decreased by high salinity levels in the irrigation water (Feizi et al , 2010). Safflower has been shown to be highly salt tolerant in terms of yield and oil production (Francois & Bernstein, 1964), although seed oil content has been reported to decrease with increasing salinity (Francois et al , 1964; Yermanos et al , 1964; Beke et al , 1995). Francois and Bernstein (1964) have attributed this oil decrease to an increase in hull percentage caused by faster physiological maturity under salt stress.…”

An intensive process of land deterioration of some regions in Uzbekistan including the Aral Sea basin has led to a significant increase in soil salinity levels and consequently to a considerable reduction of total fertile soil area, as these lands are of little use for plant growth. The area is estimated to be more than 1.4 million ha of seabed. As a result, there was an immediate need to cultivate new crops capable of stopping the movement of sands and the enlargement of saline soils. Safflower (Carthamus tinctorius) is considered to be a moderately salt-tolerant crop and, as such, one of a few crops well suited to the cropping systems of salt-affected soils. It is used in Uzbekistan as a reserve crop when the culture of the main crop fails. In spite of the great economic importance of this oil, there is almost no available information in the literature on the effect of salinity on oil quality and its chemical ingredients. The purpose of the present study was to determine, in greenhouse and field experiments, how irrigation with saline water would influence content of oil, lipids and other lipophylic components in safflower. We found that irrigation of safflower with moderate concentrations of saline water seems feasible, as far as oil and lipid composition is concerned. Consequently, safflower might be a potential crop for lands of little use for plant growth in Uzbekistan or other similar sites in the world.
