“…The use of ISSR markers has evolved rapidly and generated a large number of polymorphic bands at the intraspecific level, increasing reproducibility . This technique has already been used in numerous organisms for genetic characterisation, for assessment of genetic diversity, for identification of genetic trait loci and for understanding phylogenetic and/or interspecific relationships . Notably, ISSR was successfully used as an ideal tool for genetic structure analysis of P. xylostella populations even at low geographic scale .…”

Near-isogenic strains were constructed to provide a reliable biological system to investigate the mechanism of Cry1Ac resistance in P. xylostella. These data suggest that resistance to Cry1Ac, Cry1Ab and Cry1Ah is probably caused by the alteration of a common receptor not recognised by Cry1Ca or Cry1Ie. Understanding Bt toxin cross-resistance provides valuable information to consider when developing pest control strategies to delay resistance evolution. © 2014 Society of Chemical Industry.

“…S. tragus and S. kali ssp. austroafricana were differentially susceptible to potential biological control agents, a fungal pathogen, Colletotrichum gloeosporoides, and a gall-forming midge (Desertovellum stackelbergi) (Bruckart et al 2004;Sobhian et al 2003b). On the other hand, the eriophyid mite, Aceria salsolae, collected on S. tragus in Greece, successfully reproduced on S. tragus, S. kali ssp.…”

Tumbleweeds (Salsola species, section Kali) are road side and rangeland pest plants throughout the 48 contiguous states in the US. Three described tumbleweed species and two undescribed Salsola taxa occur in California. The known species are Russian thistle, Salsola tragus, introduced from Eurasia in the 1800s, Russian barbwire thistle, S. paulsenii, which grows in the desert regions of California, and is also native to Eurasia, and the recently identified S. kali subspecies austroafricana, possibly native to South Africa. Our goals were to investigate karyology, genome size, and molecular genetic affinities of the described species and the other taxa within their ranges in California using recently developed microsatellite loci, dominant nuclear DNA markers (RAPD and ISSR), and DNA sequence data. Chromosome counts and genome size assessments made with flow cytometry were compared. These analyses indicated that one undescribed taxon is a new allopolyploid hybrid between S. tragus and S. kali subspecies austroafricana, and the other undescribed taxon appears to be a complex hybrid involving all three described species. The invasion potentials for the hybrid taxa are unknown. Tumbleweeds are the focus of biological controls efforts but the identification of suitable agents for the hybrid taxa may be problematic because of the large amount of genetic variability encompassed within this evolving Salsola complex.

“…This species is unknown in Eurasia (Ryan et al, 2007) and may possibly be native to Australia, which is surprising considering its morphological and genetic similarity to S. tragus. Salsola australis previously has been called ''type B" by some authors (Ryan and Ayres, 2000;Sobhian et al, 2003;Ryan et al, 2007). Akhani et al (2007) recently placed all these species, with the possible exception of S. australis which was not studied, in the resurrected genus Kali, based on cladistic analysis of molecular genetic data.…”

Field assessment of host plant specificity and potential effectiveness of a prospective biological control agent, Aceria salsolae, of Russian thistle, Salsola tragus

assessment of host plant specificity and potential effectiveness of a prospective biological control agent, Aceria salsolae, of Russian thistle, Salsola tragus" (2009 The eriophyid mite, Aceria salsolae de Lillo and Sobhian, is being evaluated as a prospective classical biological control agent of invasive alien tumbleweeds, including Salsola tragus, S. collina, S. paulsenii and S. australis, in North America. Previous laboratory experiments to determine the host specificity of the mite indicated that it could sometimes persist and multiply on some nontarget plants, including Bassia hyssopifolia and B. scoparia. These are both European plants whose geographic range overlaps that of the mite, but the mite has never been observed on them in the field. A field experiment was conducted in Italy to determine if the mite would infest and damage these plants under natural outdoor conditions. The results indicate that this mite does not attain significant populations on these nontarget plants nor does it significantly damage them. Salsola tragus was heavily infested by A. salsolae, and plant size was negatively correlated to the level of infestation. Although S. kali plants were also infested, their size did not appear to be affected by the mites. The other nontarget plants were not as suitable for the mite in the field as in previous laboratory experiments. We conclude that there would be no significant risk to nontarget plants as a result of using A. salsolae as a biological agent to control Salsola species in North America.Published by Elsevier Inc.
