Schematic representation of the Alba domain and RGG/RG repeat motifs identified in SlAlba proteins. RGG/RG repeat motifs are defined in accordance with Thandapani et al. [16] as follows: the di-RGG motif consists of two repeated RGG sequences spaced 0–4 residues apart, denoted as RGG(X0–4)RGG; the deca-, octa-, hexa-, penta-, tetra-, tri-, and di-RG motifs comprise ten, eight, six, five, four, three, and two repeated RG sequences, respectively, 0–4 residues apart
