Project description:Using RNA sequencing, we compared transcriptomes of root and aerial tissues of S. parvula and Arabidopsis and identified genes and pathways with significantly different basal expression strengths. Many stress-related ion transporter genes in S. parvula showed increased copy numbers and basal expression strengths compared with Arabidopsis, with evidence of subfunctionalization. These results provide a blueprint for mechanisms of plant ion stress tolerance as well as potential genetic resources for crop improvement in closely related species. Note: All samples in SRA were assigned the same sample accession (SRS845940 and SRS845941). This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.
