To locate the genes controlling adaptability in bread wheat using AMMI (additive main effect and multiplicative interaction) model, twenty-one substitution lines derived from the parents Chinese Spring (recipient) and Chayan (donor) were used in a randomized complete block design with three replications in three different environments in the Agricultural College of Razi University, Kermanshah, ...

Secale cereale L. has been used worldwide as a source of genes for agronomic and resistance improvement. In this study, a stable wheat-rye substitution line and 3 primary 1RS.1BL translocation lines were selected from the progeny of the crossing of the Chinese local rye Aigan variety and wheat cultivar Mianyang11. The substitution and translocation lines were identified by molecular cytogenetic...

Mutation is the ultimate source of all genetic variation and is, therefore, central to evolutionary change. Previous work on Paramecium tetraurelia found an unusually low germline base-substitution mutation rate in this ciliate. Here, we tested the generality of this result among ciliates using Tetrahymena thermophila. We sequenced the genomes of 10 lines of T. thermophila that had each undergo...

Mutation is the ultimate source of all genetic variation and is, therefore, central to evolutionary change. Previous work on the ciliate Paramecium tetraurelia concluded that the presence of a transcriptionally silent germline genome has caused the evolution of a low base-substitution mutation rate in the germline genome of that ciliate. Here, we use mutation accumulation (MA) lines of the cili...

Abstmet. A method of surface definition and smoothing using a set of three-dimensional skeletal-lines is given. The skeletal-lines represent the essential features of a surface and can be individually smoothed using the first divided difference. The modified skeletal-lines are automatically generated by back substitution from the smoothed first divided difference lines. In this way a surface ca...

Developing stable Chinese hamster ovary (CHO) cell lines for biotherapeutics is an irreversible process and therefore, key quality attributes, such as sequence variants, must be closely monitored during cell line development (CLD) to avoid delay in the developmental timeline, and more importantly, to assure product safety and efficacy. Sequence variants, defined as unintended amino acid substit...
