The co-expression correlation coefficient indicated the regression linear results based on 1779 arrays. The

^aco-expression correlation ranged from −1 to +1, represented the correlation direction, closer to +1, the more positive relation. The

^bp-value indicated the strength of the correlation.

^CIn the interaction section, the Y2H means the preys were obtained from the Y2H screening from the corresponding baits, and the BiFC indicated this confirmation was performed on both XLG1 and XLG3 full length. The prey proteins used for the BiFC assay marked with ^*.
