Hassler Whitneyormation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an . strain carrying a standard binary vector. In addition to step-by-step laboratory transformation procedures, we include extensive details in growing donor plants and caring for transgenic plants in the greenhouse.无目标 发表于 2025-3-22 08:24:28

Moscow 1935: Topology Moving Toward Americaconference in a specialized part of mathematics, on a broad scale. 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 had been working up the same material.阻碍 发表于 2025-3-22 16:34:12
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 vertex.庇护 发表于 2025-3-22 18:16:00
On reducibility in the four color problemfiguration . of H. Heesch were proved “.-reducible.” A computer program has been run (considering nearly 200,000 different colorings of the boundary . of ., each one a complicated problem); the computer said “yes.” I am told that the computer was asked the wrong question.小歌剧 发表于 2025-3-23 00:43:08
