Suppression of radiation-induced tumorization in fern prothalli.
نویسنده
چکیده
By quantitative techniques it has been shown that the expected tumor frequency after x-irradiation of spores of the fern Pteridium aquilinum can be reduced by the addition of casein hydrolyzate or amino acids to the medium upon which the spores are germinated and grown into either prothalli or tumors.

Dopp (1) demonstrated that the extract from mature prothalli of the fern species Ptcridiwtn1 aquiilinunil (L.) Kuhln hastened the onset of antheridium formation in young prothalli of this species by several days and in the prothalli of Dryopteris filixwwlas (L). Schott by several weeks. Dopp's conclusion that the prothalli of P. aquilinit elaborate a specific antheridium-inducing factor was con...
متن کاملPhototropins and neochrome1 mediate nuclear movement in the fern Adiantum capillus-veneris.
In gametophytic cells (prothalli) of the fern Adiantum capillus-veneris, nuclei as well as chloroplasts change their position according to light conditions. Nuclei reside on anticlinal walls in darkness and move to periclinal or anticlinal walls under weak or strong light conditions, respectively. Here we reveal that red light-induced nuclear movement is mediated by neochrome1 (neo1), blue ligh...

Actiniopteris radiata (Swartz) Link. is a fern belonging to the family Pteridaceae. The spores collected from the pinnae of A.radiata was inoculated in Knudson’s C and Knop’s medium at pH 5.8. The ontogenic pattern such as germination type, prothallial development and micromorphological changes were studied in detail. The germination of the spore was Anemia type. The gametophyte development was...

recently a new structure called groove gap waveguide (GGW) is introduced to implement low loss microwave component devices especially for millimeter wave applications. This paper presents a new type of H-plane horn antenna making use of this new technology in which backward radiation is significantly suppressed by introducing a high impedance surface at the antenna aperture. The high impe...
