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 کاملGeographic Variation in Festuca rubra L. Ploidy Levels and Systemic Fungal Endophyte Frequencies
Polyploidy and symbiotic Epichloë fungal endophytes are common and heritable characteristics that can facilitate environmental range expansion in grasses. Here we examined geographic patterns of polyploidy and the frequency of fungal endophyte colonized plants in 29 Festuca rubra L. populations from eight geographic sites across latitudes from Spain to northernmost Finland and Greenland. Ploidy...
متن کاملDraft Genome Sequence of Pseudomonas putida Strain GM4FR, an Endophytic Bacterium Isolated from Festuca rubra L.
Pseudomonas putida GM4FR is an endophytic bacterium isolated from aerial plant tissues of Festuca rubra L. Functional annotation of the draft genome (7.1 Mb) revealed 6,272 predicted protein-encoding genes. The genome provides insights into the biocontrol and plant growth-promoting potential of P. putida GM4FR.
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 کاملمطالعه واکنش‌های فیزیولوژیک و بیوشیمیایی چمن Agrostis stolonifera و Festuca arundinacea Schreb. نسبت به تنش خشکی
تنش خشکی از مهم‌ترین عوامل محیطی محدود کننده رشد چمن‌ها در مناطق خشک و نیمه خشک است. در پژوهش حاضر، تغییرات فیزیولوژیک و بیوشیمیایی دو گونه چمن، Agrostis stolonifera var. palustris و Festuca arundinacea Schreb. var ky 31 طی یک دوره 40 روزه تنش خشکی (نیروی مکش 70-75 سانتی‌بار خاک) با فواصل زمانی 10 روز یک بار و همچنین مرحله رشد مجدد در پایان دوره تنش ارزیابی گردید. گیاهان شاهد در مدت اعمال تنش خ...
