Genetic Diversity Among Nile Delta Isolates Of Rhizoctonia Solani Kühn Based On Pathogenicity, Compatibility, Isozyme Analysis And Total Protein Pattern, Yehia A.G. Mahmoud, Reda M. Gaafar, H. M. Mubarak
Turkish Journal of Botany
The present study obtained 12 isolates from Rhizoctonia solani Kühn isolated from Cotton L., Trifolium L. and Vicia faba L. from different localities in the Nile Delta of Egypt. All strains were pathogenic and caused seed rot, wilt, stunting, and pre-emergence and post-emergence damping-off. The isolated strains produced different forms of infection cushions that ensure the pathogenicity of these strains. SDS-PAGE of the 12 R. solani isolates showed that although the R. solani isolates were isolated from very divergent host plants, the total soluble protein patterns among them were similar. Isozyme analysis revealed higher polymorphism among R. solani isolates using …

Effects Of Salinity: Calcium Interaction On Growth And Nucleic Acid Metabolism In Five Species Of Chenopodiaceae, Essam E. M. Abo-Kassem
Turkish Journal of Botany
Seed germination, seedling growth, and some enzyme activity of nucleic acid metabolism were studied in 5 members of Chenopodiaceae [Beta vulgaris L., Chenopodium quinoa Willd., Spinacea oleracea L., Allenrolfia occidentalis (S.Watson) Kuntze, Atriplex hortensis L.] under NaCl salinity alone or combined with 0.5 mM CaSO_4. High salinity delayed radical emergence and decreased germination percentage in all plants. Combined CaSO_4 reduced inhibition of seed germination in B. vulgaris, S. oleracea, and A. hortensis, but increased it in C. quinoa and A. occidentalis. CaSO_4 reduced plant growth to a greater degree than high salinity did. High salinity decreased total nucleic acid content …
Evaluation Of Karyotype Status Of Musa L. Somaclonal Variants (Musaceae: Zingiberales), Gordian C. Obute, Philip C. Aziagba
Evaluation Of Karyotype Status Of Musa L. Somaclonal Variants (Musaceae: Zingiberales), Gordian C. Obute, Philip C. Aziagba
Turkish Journal of Botany
Tissue culture regenerated materials of Musa L. spp. (banana and plantain) along with their somaclonal variants were assessed for karyotype abnormalities to be used as indicators for rapid cytological marking. The results show that although slight variations were noted in karyomorphometric characters, like chromosome number, arm length, total chromosome length, and total chromosome volume, these were not significant (P £ 0.05). Therefore, chromosomal abnormalities may not be accurate markers for somaclonal variation in these species. The need to not overemphasise chromosomal instability resulting from culture techniques was highlighted. Other possible causes of somaclonal variations were proposed to explain this phenomenon …
