Fig. 2 in Variation in the amino acids, volatile organic compounds and terpenes profiles in induced polyploids and in Solanum tuberosum varieties

Fig. 2. Biplot of Principal Component Analysis based on VOCs and Amino acids from leaves of Solanum allotetraploids (a), autotetraploids (b) and cultivated varieties (c). Components were calculated using Euclidean distances. Amino acids are depicted in the three-letter code. a) Allotetraploids (4xAL2 and 4xAL4) and diploid S. tuberosum x S. kurtzianum parental interspecific hybrid (2xPIH). b) Autotetraploids (4xAuL1, 4xAuL2 and 4xAuL3) and diploid S. kurtzianum parental line (2xPL). c) S. tuberosum cultivated varieties (4xCalen, 4xInnovator and 4xPampeana).

Fig. 3. Hierarchical cluster analysis (represented by a heat-map) of amino acids content in leaves of potato allo- and autotetraploids and cultivated varieties. Dendrograms were constructed by UPGMA clustering method for 18 amino acids and 10 lines: diploid S. kurtzianum parental line (2xPL), diploid S. tuberosum x S. kurtzianum parental interspecific hybrid (2xPIH), three autotetraploids (4xAuL1, 4xAuL2 and 4xAuL3), two allotetraploids (4xAL2 and 4xAL4) and three cultivated varieties (4xCalen, 4xInnovator and 4xPampeana).

Fig. 1 in Variation in the amino acids, volatile organic compounds and terpenes profiles in induced polyploids and in Solanum tuberosum varieties

Fig. 1. Fold change of compounds content in allotetraploids (a) and autotetraploids (b) relative to their respective diploid parental line. Fold change is expressed as log10(Tetraploid/Diploid). Horizontal lines are the average of the absolute logFC for each evaluated line, letters denote differences by Duncan's multiple range test (P <0.05).

Fig. 6. Ridgeline plot showing the distribution of the summed values of the γ-terpinene compound group (γ-terpinene, limonene, α-thujene, α-terpinene, terpinolene, and p-cymene; as % relative to total monoterpenes in each plant). In order from top to bottom: the plots coloured red (Celestún) and orange (Sisal) are located at the west of the peninsula. The plot coloured yellow (Chicxulub) is in the centre, and the cream coloured plot (Coloradas) is located at the east of the peninsula.
