Abstract

Yellow hornpoppy (Glaucium flavum Crantz.) is a herbaceous plant with gray-green leaves in coastal sands, rocky areas, and heavily eroded soils up to 500 meters above sea level. Glaucium flavum is native to Northern Africa, temperate zones in Western Asia and Europe, and is indigenous to Iran. The plant has been widely recognized for its aporphine-type isoquinoline alkaloids, which are pharmacologically active. Thus, we conducted a combination of morphological and molecular data analysis on such species because of the plant species' relevance. One hundred seven randomly collected plants from 14 natural populations in 5 provinces were evaluated using ISSR markers and morphological traits. The evaluation of molecular variance (AMOVA) demonstrated significant genetic divergence between the examined populations. It indicated that 25% of overall genetic variability was related to intra-population variety, whereas 75% was due to inter-population genetic differentiation. ISSR primers discovered 156 bands, 139 (83 %) of which have been polymorphic, each primer containing an average of 13 bands. The Polymorphic Bands (PPB) Percentage (ISSR-6) varied from 50% to 100%. (ISSR-1, ISSR-4, and ISSR-5). The average polymorphic information content (PIC), Shannon's information indexes (I), and several effective alleles (Ne) were correspondingly 0.39, 0.26, and 1.2.

木瓜科黄Glaucium flavum的群体分化与基因流动

黄角罂粟(Glaucium flavum Crantz.)是一种草本植物，叶子灰绿色，生长在沿海的沙子、岩石地区和海拔500米以上严重侵蚀的土壤中。黄Glaucium flavum原产于北非、西亚和欧洲的温带地区，原产于伊朗。该植物因其具有药理活性的阿啡类异喹啉生物碱而被广泛认可。因此，由于植物物种的相关性，我们对这些物种进行了形态学和分子数据的结合分析。采用ISSR标记和形态性状对5个省14个自然居群的107株植物进行了评价。分子方差(AMOVA)评价表明，被测群体之间存在显著的遗传差异。结果表明，总遗传变异中25%与群体内变异有关，75%与群体间遗传分化有关。ISSR引物共发现156条条带，其中139条(83%)为多态性条带，平均每个引物包含13条条带。多态性带(PPB)百分比(ISSR-6)在50% ~ 100%之间变化。(ISSR-1, ISSR-4, ISSR-5)。平均多态性信息含量(PIC)、Shannon信息指数(I)和若干有效等位基因(Ne)分别为0.39、0.26和1.2。
