Comparative Transcriptome Profiling of Two Tomato Genotypes in Response to Potassium-Deficiency Stress.

ABSTRACT: Tomato is a crop that requires a sufficient supply of potassium (K) for optimal productivity and quality. K⁺-deficiency stress decreases tomato yield and quality. To further delve into the mechanism of the response to K⁺-deficiency and to screen out low-K⁺ tolerant genes in tomatoes, BGISEQ-500-based RNA sequencing was performed using two tomato genotypes (low-K⁺ tolerant JZ34 and low-K⁺ sensitive JZ18). We identified 1936 differentially expressed genes (DEGs) in JZ18 and JZ34 at 12 and 24 h after K⁺-deficiency treatment. According to the Gene Ontology (GO) and Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway analyses, the DEGs that changed significantly primarily included transcription factors, transporters, kinases, oxidative stress proteins, and hormon
