“…Transgenic asulam-resistant potatoes infested with Orobanche and engineered with the herbicide resistance gene sul that codes for a modified dihydropteroate synthase (DHPS)-the target site of the herbicide asulam, suppressed development of the parasite after application of the herbicide asulam (Surov et al 1998; Table 4). Aviv et al (2002) engineered a mutant ALS gene into carrot, allowing the control of broomrape by imazapyr (an imidazolinone ALS inhibitor). Several tobacco cultivars transformed with a mutant acetohydroxy acid synthase (AHAS) 3R gene (isolated from a sulfonylurearesistant Brassica napus cell line) were resistant to the herbicide chlorsulfuron (Glean®, DuPont; Slavov et al 2005).…”

On a worldwide basis, parasitic weeds represent one of the most destructive and intractable problems to agricultural production in both developed and developing countries. About 20 families (3,000-5,000 species) of higher plants are parasitic on the plant kingdom and may cause production losses of 30-80% in staple food and industrial crops on every continent. Compared with the other weeds, parasitic weeds are difficult to control by conventional means because of their life style: Parasites are intimately involved with the host and have so much metabolic overlap with the host that differential treatments are very difficult to develop. In some cases, the parasites are closely associated to the host root, concealed underground, and undiagnosed until they irreversible damage the crop. Several different approaches (cultural, mechanical, chemical, use of resistant varieties, and biological) to control parasitic weeds are currently in use, but are only partially successful. Recent reviews have covered the physiology and interactions between parasitic plants and their hosts, taxonomy, and the biology and classical control of parasitic weeds. The current review will discuss why alternative methods are needed to control parasitic weeds and will summarize conventional and new biotechnologybased control measures against the major world pests Striga, Orobanche, Cuscuta, and mistletoes (Phoradendron and Viscum genera). Effectiveness, advantages and disadvantages, environment safety, and simplicity of these new biotechnological methods will be reviewed.

“…However, it is of little use in controlling broomrape, because the herbicide is degraded by the crop before it can reach the parasite. This is the case with glufosinate, which is metabolised by the product of the bar gene in transformed plants and therefore becomes ineffective for broomrape control 49…”

“…In this case, the parasite takes the herbicide together with the nutrients from the protected host and thereby accumulates toxic levels. This hypothesis has already been borne out by using transgenic crops with target‐site resistance for the acetolactate synthase (ALS), enolphosphate shikimate phosphate (EPSP) synthase and dihydropteroate synthase‐inhibiting herbicides allowing control of Striga or Orobanche 49–53. This is therefore a promising solution for controlling Orobanche in pea.…”

When people take drugs such as propranolol in response to trauma, it may dampen their bad memories – tempering recall of a traumatic event. We examined people's attitudes toward these drugs. Americans and New Zealanders read about a hypothetical assault inserting themselves into a scenario as a victim attacked while serving on a peace keeping mission (soldier role) or while walking home from a job as a restaurant manager (civilian role). Then they told us whether they should receive a memory dampening drug, and whether they would want to take a memory dampening drug. Subjects were negatively disposed towards a memory dampening drug, but Americans who adopted the soldier role were more in favor of having access to the drug than those who adopted the civilian role. We discuss the implications of these findings in relation to an increasing trend in ‘cosmetic neurology’, medicating with the goal of enhancement, rather than therapy.

“…One ALS inhibitor, sulfosulfuron (Monitor ® ), has recently been licensed in Israel for use against P. aegyptiaca in tomato fields, but it is only partially effective, and its residues may damage subsequent crops. Transgenic carrots resistant to the herbicide imazapyr allowed for movement of unmetabolised herbicide through the crop to control the attached P. aegyptiaca (Aviv et al ., ). Seed dressing with herbicides using an ALS inhibitor was also used for Striga spp.…”

Parasitic plants have evolved various methods of invading host plants. Some invade aerial parts, whereas others invade the roots to obtain necessary nutrients for their development. Phelipanche and Orobanche spp. (broomrapes) and Cuscuta spp. (dodders) are holoparasitic plants that subsist on roots and shoots, respectively, of a variety of agricultural crops. These weeds are able to connect directly with the vascular system of the host, thereby acquiring the water, minerals and carbohydrates necessary for their own growth and reproduction. This exploitation by parasitic plants often causes severe losses in yield quality and quantity of host crops. The key to an effective means for controlling parasitic plants lies in the development of resistant crops, supported by an improved understanding of broomrape and dodder biology. The
