Vacuolar Sequestration of Paraquat Is Involved in the Resistance Mechanism in Lolium perenne L. spp. multiflorum
Lolium perenne L. spp. multiflorum (Lam.) Husnot (LOLMU) is a winter annual weed, common to row crops, orchards and roadsides. Glyphosate-resistant populations of LOLMU are widespread in California. In many situations, growers have switched to paraquat or other postemergence herbicides to manage glyphosate-resistant LOLMU populations. Recently, poor control of LOLMU with paraquat was reported i...
متن کاملDifferential Resistance Mechanisms to Glyphosate Result in Fitness Cost for Lolium perenne and L. multiflorum
Multiple mechanisms of resistance to glyphosate are exhibited by populations of Lolium spp. worldwide. Association of resistance with growth and reproductive fitness is an important predictor for long-term success of glyphosate-resistant (R) versus glyphosate-susceptible (S) biotypes. Numerous studies were conducted on R- and S-biotypes of Italian ryegrass (Lolium multiflorum) and perennial rye...
متن کاملکارایی نشانگر مولکولی SCoT در بررسی تمایز دو گونه Lolium perenne و Lolium multiflorum
چچم یکی از گیاهان مهم علوفهای در مناطق سردسیری جهان میباشد و در شرایط مختلف آب و هوایی رشد میکند. تنوع ژنتیکی دو گونه بین نه ژنوتیپ از Lolium perenne و نه ژنوتیپ از Lolium multiflorum با استفاده از 15 نشانگر مولکولی SCoT بررسی شد. آغازگرهای ScoT در مجموع 86 باند تولید کردند که از این تعداد 12 باند یکشکل مشاهده شد و سایر باندها چندشکل بودند. آغازگرهای SC35، SC36 و SC26 بهترتیب با 9 و 8 ب...
متن کاملImplementation of Genomic Prediction in Lolium perenne (L.) Breeding Populations
Perennial ryegrass (Lolium perenne L.) is one of the most widely grown forage grasses in temperate agriculture. In order to maintain and increase its usage as forage in livestock agriculture, there is a continued need for improvement in biomass yield, quality, disease resistance, and seed yield. Genetic gain for traits such as biomass yield has been relatively modest. This has been attributed t...
متن کاملGenetic diversity and relationships in cultivars of Lolium multiflorum Lam. using sequence-related amplified polymorphism markers.
Sequence-related amplified polymorphism (SRAP) markers were used to analyze and estimate the genetic variability, level of diversity, and relationships among 20 cultivars and strains of annual ryegrass (Lolium multiflorum Lam.). Eighteen SRAP primer combinations generated 334 amplification bands, of which 298 were polymorphic. The polymorphism information content ranged from 0.4715 (me10 + em1)...
