Summary Twelve molecular markers linked to pseudogamous apospory, a form of gametophytic apomixis, were previously isolated from Pennisetum squamulatum Fresen. No recombination between these markers was found in a segregating population of 397 indivi

Isolation of genes controlling apomixis would be useful to plant breeders for fixing hybrid vigor. A single gene codes for aposporous apomixis in buffelgrass [Pennisetum ciliare (L.) Link]. This study was undertaken to assess the feasibility of using

Smooth bromegrass (Bromus inermis Leysser) germplasm PL-BDR1 and two seed increase generations derived from it are highly resistant to brown leaf spot caused by Pyrenophora bromi (Died.) Drechs. [Drechslera bromi (Died.) Shoemaker, conidial state = H

Previous studies on inheritance of monopolar (Panicum type) apospory in the Panicoideae resulted in three widely different genetic models and mutually incompatible data sets. We report additional data for tetraploid buffelgrass [Pennisetum ciliare (L

Genetic resistance is the only practical method to control foliar diseases on forage grasses. Once developed, resistance must be transmitted, without selection, through several generations of seed increase. This study was conducted to determine wheth

Sexual and aposporous apomictic embryo sac development in three Cenchrus ciliaris genotypes was evaluated in situ and in vitro. An aseptic procedure was developed to culture involucres in which the pistils contained archesporial cells. Development of

One new and 5 known flavone C -glycosides were isolated from leaves and stems of Coronilla varia . The new compound was shown to be isoorientin 2″- O -rhamnoside. The known compounds were isovitexin, isoorientin, isovitexin 4′- O -glucoside, isoo

The relationship of peroxidases to an inducible disease-resistance mechanism involving lignification of leaf epidermal cell walls was studied. Reed canarygrass (Phalaris arundinacea L.) leaf discs were inoculated with Helminthosporium avenae Eidam an

Lignin content and enzymes involved in lignification were measured in leaf discs of reed canarygrass (Phalaris arundinacea L.) inoculated with Helminthosporium avenae and floated on water or solutions of cycloheximide (25 mug/ml). Fungal germ tubes d
