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...

Differential 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...

کارایی 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...

Implementation 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...

PART OF A HIGHLIGHT ON BREEDING STRATEGIES FOR FORAGE AND GRASS IMPROVEMENT New chloroplast microsatellite markers suitable for assessing genetic diversity of Lolium perenne and other related grass species

†Background and Aims Lolium perenne (perennial ryegrass) is the most important forage grass species of temperate regions. We have previously released the chloroplast genome sequence of L. perenne ‘Cashel’. Here nine chloroplast microsatellite markers are published, which were designed based on knowledge about genetically variable regions within the L. perenne chloroplast genome. These markers w...
