A Systematic View Exploring the Role of Chloroplasts in Plant Abiotic Stress Responses

Figure 4

Heatmap analysis of cold- and heat-responsive plastid genes which show leaf-preferred or ubiquitous expression patterns. Heatmap of cold or heat stress-responsive plastid-related genes. Similarly to the anatomy clustering, we used KMC algorithm with Euclidean distance matric to cluster abiotic-responsive genes. To define stress responsiveness, we applied criteria that were greater than average 1 log₂-fold change (2-fold) in each stress and p-value less than 0.05 in one-way ANOVA test. As a result, we identified 264 cold or heat stress-responsive plastid genes.
