Establishment of transgenic herbicide-resistant creeping bentgrass (Agrostis stolonifera L.) in nonagronomic habitats.
Concerns about genetically modified (GM) crops include transgene flow to compatible wild species and unintended ecological consequences of potential transgene introgression. However, there has been little empirical documentation of establishment and distribution of transgenic plants in wild populations. We present herein the first evidence for escape of transgenes into wild plant populations wi...
متن کاملExpression of a Novel Antimicrobial Peptide Penaeidin4-1 in Creeping Bentgrass (Agrostis stolonifera L.) Enhances Plant Fungal Disease Resistance
BACKGROUND Turfgrass species are agriculturally and economically important perennial crops. Turfgrass species are highly susceptible to a wide range of fungal pathogens. Dollar spot and brown patch, two important diseases caused by fungal pathogens Sclerotinia homoecarpa and Rhizoctonia solani, respectively, are among the most severe turfgrass diseases. Currently, turf fungal disease control ma...
متن کاملCloning and expression of the 1-aminocyclopropane-1-carboxylic oxidase gene from Agrostis stolonifera.
A gene encoding 1-aminocyclopropane-1-carboxylic oxidase (ACO), which catalyzes the terminal step in ethylene biosynthesis, was isolated from Agrostis stolonifera. The AsACO gene is composed of 975 bp, encoding 324 amino acids. Three exons interspersed by two introns form AsACO gDNA. A BLAST search of the nucleotide sequence revealed a high level of similarity (79-91%) between AsACO and ACO gen...
متن کاملEcophylogeny of the endospheric root fungal microbiome of co-occurring Agrostis stolonifera
BACKGROUND Within the root endosphere, fungi are known to be important for plant nutrition and resistance to stresses. However, description and understanding of the rules governing community assembly in the fungal fraction of the plant microbiome remains scarce. METHODS We used an innovative DNA- and RNA-based analysis of co-extracted nucleic acids to reveal the complexity of the fungal commu...
متن کاملCultivation Effects on Organic Matter Concentration and Infiltration Rates of Two Creeping Bentgrass (Agrostis stolonifera L.) Putting Greens
Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...
