Genetic Transformation of Elite Turf-type Cultivars of Tall Fescue
Biotechnology approaches can supplement conventional breeding efforts for turfgrass improvement. The objective of this study was to develop reliable transformation and selection schemes for elite turf-type tall fescue cultivars. Transgenic tall fescue (Festuca arundinacea Schreb.) plants were obtained by microprojectile bombardment of embryogenic suspension cells of two elite turf-type cultivar...
متن کاملHigh efficiency transformation of tall fescue with Agrobacterium tumefaciens
An efficient genetic transformation system for tall fescue ( Festuca arundinacea Schreb.), using Agrobacterium tumefaciens-mediated TDNA delivery, is described. Seed-derived embryogenic calli were infected with Agrobacterium tumefaciens strain EHA105 harboring plasmids pTOK47 and pCAMBIA1301. Infected calli were selected at 250 mg L 1 hyg B and the regenerated plantlets at 50 mg L . Using the p...
متن کاملA Preliminary Experiment on Agrobacterium tumefaciens-Mediated Transformation of the P5CS1 GENE in Tall Fescue
Abiotic stress conditions can be imposed on plants through either poor water quality or adverse climate condition. These types of stress affect plant growth and development throughout their life cycle. Plants that are tolerant to drought are therefore valuable, and turf grasses have the potential to grow tolerant. Turf grasses provide ground cover and offer multiple benefits, from their aesthet...
متن کاملGenetic diversity in a world germplasm collection of tall fescue
Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated that it contains different species from the genus Festuca and allowed their rapid classification into the three major morphotypes (Continental, Mediterranean and Rhizomatous...
متن کاملTall Fescue Toxicosis
widely used forage crop. It is insect and nematode resistant, tolerates poor soil and climatic conditions well and has a long growing season. Unfortunately, tall fescue also has a downside. Most tall fescue in the state is infected with a fungal endophyte, Neotyphodium coenophialum (formerly called Acremonium coenophialum) that is toxic to animals. Tall fescue was brought to this country from E...
