    Journal PapersFrontiers in Plant Science , Volume 11 , 2021 February 15, {Pages 2326 }

    Abstract

    Tolerance to salinity is a complex genetic trait including numerous physiological processes, such as metabolic pathways and gene networks; thereby, identification of genes indirectly affecting, as well as those directly influencing, is of utmost importance. In this study, we identified and elucidated the functional characterization of AtPAP17 and AtPAP26 genes, as two novel purple acid phosphatases associated with high-salt tolerance in NaCl-stressed conditions. Here, the overexpression of both genes enhanced the expression level of AtSOS1, AtSOS2, AtSOS3, AtHKT1, AtVPV1, and AtNHX1 genes, involving in the K+/Na+ homeostasis pathway. The improved expression of the genes led to facilitating intracellular Na+ homeostasis and decreasing the io

    Abstract

    Persian poppy (Papaver bracteatum Lindl.) is a perennial medicinal plant belonging to the Papaveraceae family that is endemic to the mountainous areas in Northern Iran. It is known for high amounts of the valuable benzylisoquinoline alkaloid thebaine. The effects of induced polyploidy as well as the effect of methyl Jasmonate (MeJA) elicitation on the root production of thebaine and on the expression of five alkaloid biosynthesis related genes were studied. The in vitro tetraploidy induction caused a significant increased expression of norcoclaurine synthase (NCS) and salutaridinol (SAT), and a significant decreased expression of berberine bridge enzyme (BBE) in the leaves. In the root tissues, the BBE, NCS, and SAT showed an increased expr

    Abstract

    Pears (Pyrus spp.) mainly are divided into two main groups of Asian and European species with a wide diversity or similarity in fruit and morphological traits. In this study, flow cytometry was performed to evaluate the genome size of 37 cultivars and genotypes of Asian, European, and Iranian indigenous pears. Besides, the relationship between cytological and morphological traits was investigated for the first time. Morphological traits were measured based on the International Union for the Protection of New Varieties of Plants (UPOV) descriptor. There were positive relationships between genome size, the fruit pedicel length, and the length to fruit diameter ratio. Although, as the genome size was increased, the fruit diameter and size were

    Abstract

    Papaver bracteatum Lindl. grows as a wild perennial medicinal plant in Northern Iran and is known mainly for its high amounts of the pharmaceutically valuable alkaloid of thebaine. In vitro production of tetraploid P. bracteatum through colchicine treatment of imbibed seeds is reported. Resulted tetraploid and mixoploid plants were effectively identified by chromosome counting and flow cytometry technique. The chromosome number in diploid and successfully induced tetraploids were confirmed to be 2n= 2x= 14 and 2n= 4x= 28, where their calculated 2C DNA values were 6.15?0.03 and 11.95?0.07 pg, respectively. The highest induction efficiency was obtained by colchicine concentration of 0.05% and the treatment duration of 24 h. The effects of col

    Journal PapersPlant Cell, Tissue and Organ Culture (PCTOC) , Volume 137 , Issue 3, 2019 June 1, {Pages 627-635 }

    Abstract

    Garden cress (Lepidium sativum L., Brassicaceae) is one of the most popular leafy vegetables which is widely used, and has also various medicinal properties and industrial usage. Small and very delicate leaves of this short period and fast growing species cause lots of crop losses along production to consumption; so it was supposed that increase in thickness and size of the leaves via induction of polyploidy possibly will improve post-harvest quality. Primary trial proved that seed treatments, via immersion of dry and wet seeds in different concentrations and durations of colchicine, were completely ineffective. Thereafter dropping method was conducted on apical bud of cotyledon and two true leaf stages with different concentra

    Abstract

    Artemisinin is an efficient anti-malarial drug and it possesses biological activity against a wide range of cancers. The combined application of two different elicitors can be an efficient way to increase the production of secondary metabolite in plant cell cultures. The results of coronatine (Cor) pretreatment and three concentrations of sorbitol were assessed on the growth, biochemical traits, expression of artemisinin biosynthetic genes, and artemisinin production in Artemisia annua cell suspension culture (CSC). After pretreating CSC with 0.05??M Cor [on the 14th day (three days before the stationary phase) for 48?h], liquid medium in the culture flasks was decanted and replaced with fresh medium (containing 30?g/L sucrose)

    Abstract

    Papaver bracteatum, belonging to Papaveraceae, is considered to be a primary ingredient in the production of codeine and anti-drug drugs (e.g., naloxone and Naltrexone) without the involvement of morphine. For polyploidy induction, papaver seedlings were treated with various colchicine concentrations (0, 0.05, 0.1, 0.2 and 0.5% w/v) in three time durations (24, 48 and 72?h). The effects of polyploidy induction on morphological, physiological, alkaloid production and gene expression levels in the pathway of benzylisoquinoline alkaloids were analyzed. High rates of seedling survival were observed at lower colchicine concentrations (0.05 and 0.1% w/v) versus higher concentrations (0.2 and 0.5% w/v). The best polyploidy treatment
