Proteomic profile data of Klebsormidium nitens alga grown in control and saline conditions

<i>Klebsormidium nitens (K. nitens)</i> is an alga of the charophyte class used as a model for studying the adaptation of plants to terrestrial life. Its genome has been completely sequenced and 16,215 protein-coding genes have been predicted. In this study, the proteome of <i>K. nitens</i> grown under standard conditions or after salt stress was investigated. A total of 1190 proteins were experimentally confirmed and 922 of them were classified according to their cellular location, molecular or biological function. Of these 922 proteins, 62 and 124 were specifically found in the control and salt-treated samples, respectively. However, no specific function or location could not be assigned on the basis of the primary sequences. A protein-protein interaction network based on the 124 proteins found in saline conditions was constructed using STRING analysis. All the data are accessible and are of interest for phycologists, as well as for evolutionary plant biologists, and provide a foundation for future studies investigating how <i>K. nitens</i> responds to salt stress.
