determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

trr14 is a novel protein important in trehalose (α-d-glucosyl-[1,1]-α-d-glucopyranoside) signaling in arabidopsis. in this research, we provided evidences to demonstrate that trr14 plays role in arabidopsis responses to salt and drought stress. the transgenic arabidopsis plants over-expressing trr14 under the control of camv 35s promoter were generated. transformed lines showed higher transcrip...

objective: as we are approaching the global eradication of wild poliovirus, laboratory surveillance of poliovirus by the gold standard cell culture method becomes increasingly important. as there is a lot of concern about accurate and sensitive detection of imported wild and vaccine derived polioviruses (vdpvs) in polio-free countries, in this study we assessed and compared the sensitivity of t...

Polyploidy is a common phenomenon occurring in a vast number of land plants. Investigations of patterns of inheritance and the origins of plants (i.e., autopolyploidy vs. allopolyploidy) usually involve cytogenetic and molecular studies of chromosome pairing, chromosome mapping, and marker segregation analysis through experimental crosses and progeny tests. Such studies are missing for most wil...

A number of genetic systems are described which involve the use of the yeast Saccharomyces cerevisiae. The systems may be used to detect the production of aneuploid cells produced during both mitotic and meiotic cell division in the presence of genetically active chemicals. During mitotic cell division, monosomic colonies (2n - 1) may be detected by plating upon selective medium. Increases in s...

Common bermudagrass [C. dactylon (L.) Pers. var. dactylon] is economically and environmentally the most important member among Cynodon species because of its extensive use for turf, forage and soil erosion control in the world. However, information regarding the inheritance within the taxon is limited. Accordingly, the objective of this study was to determine qualitative inheritance mode in com...

INTRODUCTION Although cetuximab and panitumumab show an increased efficacy for patients with KRAS-NRAS-BRAF and PI3KCA wild-type metastatic colorectal cancer, primary resistance occurs in a relevant subset of molecularly enriched populations. PATIENTS AND METHODS We evaluated the outcome of 68 patients with advanced colorectal cancer and RAS, BRAF and PI3KCA status according to ALK gene statu...

Intra- and interspecific cross combinations between the tetraploid treefrog Hyla versicolor, and between H. versicolor and the diploid treefrog Hyla chrysoscelis were performed. Progeny phenotypes resulting from these crosses were examined electrophoretically using a polymorphic glutamate oxaloacetic transaminase (GOT-1) locus, to determine the mechanism of chromosome segregation in H. versicol...
