Fig. 6From: The LEA gene family in tomato and its wild relatives: genome-wide identification, structural characterization, expression profiling, and role of SlLEA6 in drought stressClustering heat map of LEA genes from leaves of cultivated and wild tomato species under (a) normal and (b) abiotic stress conditions. Salt stress: S. lycopersicum (salt-susceptible cultivar) versus S. pimpinellifolium (salt-tolerant wild tomato species) (GEO accession number GSE16401). Plants were treated with 200 mM NaCl for 5 h. Drought stress: S. lycopersicum (drought-susceptible cultivar) versus S. habrochaites (drought-tolerant wild tomato species) (GEO accession number GSE22304). Plants were subjected to water stress by holding water for 7 d. Heat stress: S. lycopersicum (heat-susceptible cultivar) versus S. habrochaites (heat-tolerant wild tomato species) (GEO accession no. GSE22304). Plants were treated at a high temperature of 40 ℃ for 1 hBack to article page
