Hassler Whitneyf taro is more efficient than the particle bombardment transformation method based on current research. The development of a regeneration system starting from taro shoot tip explants could produce dasheen mosaic virus (DsMV)-free plantlets. Highly regenerative calluses could be developed from DsMV-f

Next, there were three major breakthroughs toward future methods in topology of great import for the future of the subject. And, more striking yet, in each of these the first presenter turned out not to be alone: At least one other h

Congruent Graphs and the Connectivity of Graphsraphs. These last theorems might also be proved by topological methods. The definitions and results of a paper by the author on “Non-separable and planar graphs,” † will be made use of constantly. We shall refer to this paper as N. For convenience, we shall say two arcs touch if they have a common v

Planar Graphsf it contains neither of two certain graphs within it. The author has shown .) (I, Theorem 29) that a graph is planar if and only if it has a dual as defined in I. It is the main purpose of the present paper to give a proof of the purely combinatorial theorem (Theorem 12 that a graph has a dual if a

We describe here an . root transformation protocol that can be used to determine transformation frequencies for wild-type and mutant . strains and for various . wild-type and mutant lines.
