Fig. 3From: Comparative transcriptome study provides insights into acquisition of embryogenic ability in upland cotton during somatic embryogenesisPrincipal component analysis on NEC and EC samples of CCRIÂ 12 and CCRIÂ 24 (bad correlative duplicates were removed). NEC samples of CCRIÂ 12 and CCRIÂ 24 were divided clearly into two clusters, while EC samples of CCRIÂ 12 and CCRIÂ 24 mingled. PC1 stands for principle component 1, and PC2 stands for principle component 2Back to article page
