We intend to apply MAB to improve Nitrogen Use Efficiency (NUE) and biomass conversion in corn that is adapted to North America Production environments.

Abstract. Self-incompatibility (SI) is a genetically controlled mechanism to prevent inbreeding in flowering plants. Ryegrasses (Lolium spp.) display a gametophytic self-incompatibility response controlled by the two multi-allelic loci S and objective is to identify genes involved in the self-incompatibility response in perennial ryegrass, using the cDNA-AFLP : Inge Van Daele, Erik Van Bockstaele, Isabel Roldán-Ruiz.

Perennial ryegrass is an obligate outbreeding pasture grass of the Poaceae family, with a two-locus (S and Z) gametophytic self-incompatibility (SI) mechanism. This system has provided a major obstacle to targeted varietal development, and enhanced knowledge is expected to support more efficient breeding strategies.

Comparative genetics and physical mapping approaches have been developed to. Perennial ryegrass (Lolium perenne L.) is one of the most important forage crops worldwide. Its outcrossing nature is caused by self-incompatibility (SI), a genetic mechanism preventing self-pollination in most forage grasses.

Pages Identification and Mapping of Self-incompatibility Related Genes in Lolium perenne. Pages Perennial ryegrass (Lolium perenne) is a diploid (2n = 2x = 14) member of the subfamily Pooideae, belonging to the tribe Poeae, genus Lolium. First attempts to describe synteny between Poeae, Aveneae, and Triticeae species found that the genetic maps of perennial ryegrass and Triticeae cereals are conserved in terms of orthology and.

Septem The Lolium perenne genome untitled “A synteny-based draft genome sequence of the forage grass Lolium perenne” was successfully accepted for publication in The Plant Journal.

J There is a rising interest of moving towards hybrid breeding in outcrossing species. Self-compatibility (SC), which occurs at low rates in self-incompatible species, could be used to develop inbred lines, a key requirement for hybrid breeding programs.

In perennial ryegrass, the existence of SC independent from the self-incompatibility (SI) loci S and Z has been reported. Lolium perenne (perennial ryegrass) is the most widely cultivated forage and amenity grass species in temperate areas worldwide and there is a need to understand the genetic architectures of key agricultural traits and crop characteristics that deliver wider environmental services.

Ryegrass occurs naturally as a diploid (2n=14). However, several autotretraploid cultivars were obtained via colchicination. Ryegrass displays a two-locus gametophytic self-incompatibility system (SI) that remains.
