Ribonuclease A (RNase A) enzyme was immobilized on solid holders by matrix-assisted pulsed laser evaporation (MAPLE) technique. The experiments were performed inside a stainless steel irradiation ...chamber. A UV KrF* (λ = 248 nm, τ
FWHM
≅ 25 ns, ν = 10 Hz) excimer laser source was used for irradiations. Surface morphology, molecular structure, and enzymatic activity of laser transferred RNase A samples were investigated as a function of RNase A concentration in the frozen composite MAPLE targets. Surface morphology and thickness of the immobilized enzyme were investigated by atomic force microscopy, scanning electron microscopy, and surface profilometry. The molecular structure of the laser transferred RNase A was determined by Fourier transform infrared spectroscopy. The enzymatic activity of RNase A after immobilization was tested through ribonucleic acid removal from deoxyribonucleic acid (DNA) extract solutions isolated from plant and animal tissues. A molecular method based on polymerase chain reaction was used to investigate the functional properties of DNA extracts treated with laser immobilized RNase A.
We describe the first reported intergeneric, which naturally occurs between two subspecies belonging to different genera, Dactylorhiza fuchsii subsp. sooana (genus Dactylorhiza) and Pseudorchis ...albida subsp. tricuspis (genus Pseudorchis), as × Pseudorhiza nieschalkii (Senghas) P.F.Hunt nothosubsp. siculorum H.Kertész & N.Anghelescu, 2020. The hybrid was found and digitally photographed for the first time by Hajnalka Kertész in June, 2020, within Terra Siculorum, in one of the Natura 2000 protected areas, known as Harghita Mădăraș, ROSCI00090. Following detailed morphometric analysis using 67 characters and molecular karyological analyses, we identified this unique specimen as an intergeneric hybrid, new to science. The hybrid, an F1 generation plant, most likely representing a single intergeneric pollination event, is phenotypically intermediate between its parental species in most of the characters scored, but it significantly closely resembles Pseudorchis albida subsp. tricuspis parent. Since several individuals of the parental species occurred in near proximity, within 1-10 meters distance, we suggest that the production of this hybrid required a minimum travel distance of ca 1-10 meters, by the pollinators and frequent exchange of pollen between the parental species was very likely. The parental species and the hybrid, which display a considerable synchronicity in their flowering time, overlap in the pollinator community, sharing various species of Hymenopterans and Dipterans, very abundant in the heathland. This Terra Siculorum hybrid is thus best described as a rarely occurring intergeneric hybrid that shows strong Pseudorchis albida subsp. tricuspis parental dominance in inheritance patterns.
