| contents | Cross-species dissection of saline-related genes by genetically deciphering a euryhaline microalga Chlorella sp. Wang, Aoqi Gan, Qinhua Xin, Yi Deng, Ying Han, Xiao Lu, Yandu Chlorella Microalgae Salinity Phylogeny Salt Tolerance Deciphering adaptation to habitat shifts across the salinity boundary necessitates investigation of "lost" and "acquired" saline genes. By assembling a telomere-to-telomere genome, we propose that the euryhaline Chlorophyta Chlorella sp. MEM25 represents an early-diverging saltwater species that has evolved numerous genes essential for saltwater-freshwater transitions. By comparison with Viridiplantae genomes, we identify ancestral genes and lineage-specific genes related to salinity adaptation. Loss-of-function mutants of the proposed salt-sensitive genes in algae and plants exhibit increased salt resistance, highlighting the potential of the MEM25 genome as a breeding resource. Notably, the gene RMI1 plays an important role in salinity tolerance across species, from microalgae to higher plants. |
