Genetic structure and diversity of natural populations of prickly lettuce (Lactuca serriola) were studied using AFLP markers and then compared with the diversity of the RGC2 disease resistance gene cluster. Screening of 696 accessions from 41 populations using 319 AFLP markers showed that eastern Turkish and Armenian populations were the most diverse populations and might be located in the orig...

New data on 10 adventive plant species are given. Two and one subspecies (Atriplex hortensis, Solanum nigrum subsp. schultesii, Nepeta cataria) new for the Republic of Buryatia. Five two interspecies hybrids (Arctium × mixtum, Galinsoga parviflora, Hesperis pycnotricha, Lactuca serriola, Medicago varia, Onobrychis viciifolia, Viola tricolor) recorded first time in Ulan-Ude city its neighborhood.

This work addresses the issue of Zn, Cu, Pb, Cd, Ni and Cr accumulation in wildgrown plants in the context of their possible use for the sanitation of sludge and waste substrates. The highest contents of heavy metals were noted in Lactuca serriola, Chenopodium album, Artemisia vulgaris and Atriplex nitens. Assuming maximum crop production which is to be obtained from sludge and waste substrates...

Prickly lettuce (Lactuca serriola L., Asteraceae), a wild relative of cultivated lettuce, is an autogamous species which greatly expanded throughout Western and Northern Europe during the last 2 centuries. Here, we present a large-scale biogeographic genetic analysis performed on a dataset represented by 2622 individuals from 110 wild European populations. Thirty-two maternally inherited chloro...

the specimens of the mealybug peliococcus kimmericus (kiritshenko) were collected on lactuca serriola l. from different parts of the fars province, iran. four parasitoid wasps, anagyrus orbitalis (ruschka), leptomastix histrio mayr, cheiloneurus kollari (mayr) and c. paralia (walker) (hym.: encyrtidae), were reared from this mealybug and the identifications confirmed by dr zhihong xu. the relat...

Background: Desert condition in which plants grow and survive and altering biochemical properties of plants are known to increase the secondary metabolite induction in a variety of medicinal plants. Cancer is a terrible disease and fighting it is of abundant significance to public health. Aims and Objective: To search for new compounds with cytotoxic activity isolated from natural source. In th...
