Four representative species from three genera of gram-negative bacteria that secrete exopolysaccharides acquired resistance to the antibiotic bacitracin by stopping synthesis of the exopolysaccharide. Xanthomonas campestris, Sphingomonas strains S-88 and NW11, and Escherichia coli K-12 secrete xanthan gum, sphingans S-88 and NW11, and colanic acid, respectively. The gumD gene in X. campestris i...
Tıbbi ve aromatik bitkilerden olan kekik, önemli ihraç ürünlerinden biridir. Daha çok baharat olarak tüketilen kekik pek alanda kullanılmaktadır. Ege Bölgesinde özellikle Denizli İlinde yoğun üretim yapılmaktadır. İli İzmir kekiği (Origanum onites L.) tarlalarında yürütülen çalışmada; söz konusu alanlarda bulunan yabancı ot türleri tespit edilmiş, yoğunlukları rastlanma sıklıkları belirlenmiş, ...
By washing out (14)C-solutes or (3)H-solutes in 0.5 mm CaSO(4) during a period of 5 to 6 hours, the release of amino acids by excised stem segments of broad bean (Vicia faba L. cv Witkiem) was studied. Three hours after pulse labeling with l-valine, l-asparagine, or alpha-aminoisobutyric acid (AIB), hollow stem segments were excised from the plant and incubated in a washout solution.In experime...
In the present study, xanthophyll composition of eight parasitic Cuscuta species under different light conditions was investigated. Neoxanthin was not detected in four of the eight species examined, while in others it occurred at the level of several percent of total xanthophylls. In C. gronovii and C. lupuliformis it was additionally found that the neoxanthin content was considerably stimulate...
The random amplified polymorphic DNA method was used to distinguish strains of Xanthomonas campestris pv. pelargonii from 21 other Xanthomonas species and/or pathovars. Among the 42 arbitrarily chosen primers evaluated, 3 were found to reveal diagnostic polymorphisms when purified DNAs from compared strains were amplified by the PCR. The three primers revealed DNA amplification patterns which w...
Of ten mushroom cultures investigated, only Agaricus campestris, Boletus indecisus, and Tricholoma nudum were capable of growing in submerged culture in medium of vinasse with added salts. Higher fermentative efficiencies were found under these conditions than in medium containing molasses or waste sulfite liquor. A. campestris showed a better capacity to produce protein but, since B. indecisus...
The importance of plant volatiles in mediating interactions between plant species is much debated. Here, we demonstrate that the parasitic plant Cuscuta pentagona (dodder) uses volatile cues for host location. Cuscuta pentagona seedlings exhibit directed growth toward nearby tomato plants (Lycopersicon esculentum) and toward extracted tomato-plant volatiles presented in the absence of other cue...
We investigate braneworlds modeled by topological solutions that arise from the so-called Cuscuta-Galileon model. develop a first order framework and illustrate our procedure with scalar field having well-known hyperbolic tangent profile. find conditions must be imposed to parameters of model in have connecting minima potential, brane constrained interpolate Minkowski anti de Sitter geometries....
During the development of the haustorium, searching hyphae of the parasite and the host parenchyma cells are connected by plasmodesmata. Using transgenic tobacco plants expressing a GFP-labelled movement protein of the tobacco mosaic virus, it was demonstrated that the interspecific plasmodesmata are open. The transfer of substances in the phloem from host to the parasite is not selective. Afte...
