Finding the shortest tour visiting all given points at least ones belongs to the most famous optimization problems until today (TSP . . . travelling salesman problem). Optimal solutions exist for many problems up to several ten thousand points. The major difficulty in solving larger problems is the required computational complexity. This shifts the research from finding the optimum with no time limitation to approaches that find good but sub-optimal solutions in pre-defined limited time. This paper proposes a new approach for two-dimensional symmetric problems with more than a million coordinates that is able to create good initial tours within few minutes. It is based on a hierarchical clustering strategy and supports parallel processing. In addition, a method is proposed that can correct unfavourable paths with moderate computational complexity. The new approach is superior to state-of-the-art methods when applied to TSP instances with non-uniformly distributed coordinates.

Arabidopsis thaliana polyamine oxidase 5 gene (AtPAO5) functions as a thermospermine (T-Spm) oxidase. Aerial growth of its knock-out mutant (Atpao5-2) was significantly repressed by low dose(s) of T-Spm but not by other polyamines. To figure out the underlying mechanism, massive analysis of 3’-cDNA ends was performed. Low dose of T-Spm treatment modulates more than two fold expression 1,398 genes in WT compared to 3186 genes in Atpao5-2. Cell wall, lipid and secondary metabolisms were dramatically affected in low dose T-Spm-treated Atpao5-2, in comparison to other pathways such as TCA cycle-, amino acid- metabolisms and photosynthesis. The cell wall pectin metabolism, cell wall proteins and degradation process were highly modulated. Intriguingly Fe-deficiency responsive genes and drought stress-induced genes were also up-regulated, suggesting the importance of thermospermi’ne flux on regulation of gene network. Histological observation showed that the vascular system of the joint part between stem and leaves was structurally dissociated, indicating its involvement in vascular maintenance. Endogenous increase in T-Spm and reduction in H2O2 contents were found in mutant grown in T-Spm containing media. The results indicate that T-Spm homeostasis by a fine tuned balance of its synthesis and catabolism is important for maintaining gene regulation network and the vascular system in plants.
