About this 3D model

This is a 3D sculpture of a Principal Component Analysis performed on the expression profiles of >20,000 genes from Solanum lycopersicum (domesticated tomato) and a desert relative, Solanum pennellii. Gene expression was sampled in the inflorescence, mature leaf, root, seedling, stem, and vegetative apex. This sculpture is derived from the PCs 1-3 (x, y, z), with each "rod" representing data from a single gene. Data used in this sculpture is derived from the linked publication (http://www.ncbi.nlm.nih.gov/pubmed/23585653). Data pertaining to the PCA is below: Percent variance explained by each PC: PC1: 34.4% variance PC2: 23.9% variance PC3: 20.1% variance PC1 loadings Inflorescence: 0.004 Leaf: 0.239 Root: -0.477 Seedling: 0.379 Stem: -0.461 Vegetative Apex: 0.600 PC2 loadings: Inflorescence: -0.740 Leaf: 0.646 Root: 0.047 Seedling: 0.015 Stem: 0.096 Vegetative Apex: -0.151 PC3 loadings: Inflorescence: 0.300 Leaf: 0.354 Root: -0.559 Seedling: -0.556 Stem: 0.398 Vegetative Apex: 0.069
