Evaluation of buffalograss genotypes and full-sibs for chinch bug resistance.

Fifteen buffalograss, Buchloe dactyloides (Nutt.) Engelm, genotypes and 94 diploid full-sib progeny were evaluated for western chinch bug, Blissus occiduus Barber (Hemiptera: Lygaeidae), resistance in two separate studies. The experimental design for each study was a completely randomized design.

Genome-wide profiling and analysis of Festuca arundinacea miRNAs and transcriptomes in response to foliar glyphosate application.

Glyphosate is a broad spectrum herbicide which has been widely used for non-selective weed control in turfgrass management. Festuca arundinacea cv. Falcon was shown to be one of the tolerant turfgrass species in response to varying levels of glyphosate [5% (1.

Polyploidy creates higher diversity among Cynodon accessions as assessed by molecular markers.

Developing a better understanding of associations among ploidy level, geographic distribution, and genetic diversity of Cynodon accessions could be beneficial to bermudagrass breeding programs, and would enhance our understanding of the evolutionary biology of this warm season grass species. This study was initiated to: (1) determine ploidy analysis of Cynodon accessions collected from Turkey, (2) investigate associations between ploidy level and diversity, (3) determine whether geographic and ploidy distribution are related to nuclear genome variation, and (4) correlate among four nuclear molecular marker systems for Cynodon accessions' genetic analyses. One hundred and eighty-two Cynodon accessions collected in Turkey from an area south of the Taurus Mountains along the Mediterranean cost and ten known genotypes were genotyped using sequence related amplified polymorphism (SRAP), peroxidase gene polymorphism (POGP), inter-simple sequence repeat (ISSR), and random amplified polymorphic DNA (RAPD).

Molecular characterization of cDNA encoding resistance gene-like sequences in Buchloe dactyloides.

Current knowledge of resistance (R) genes and their use for genetic improvement in buffalograss (Buchloe dactyloides [Nutt.] Engelm.) lag behind most crop plants.

Evolution of Buchloë dactyloides based on cloning and sequencing of matK, rbcL, and cob genes from plastid and mitochondrial genomes.

Buffalograss (Buchloë dactyloides (Nutt.) Englem), a C4 turfgrass species, is native to the Great Plains region of North America. The evolutionary implications of buffalograss are unclear.
