The basic residues in pollux are proposed to bind proteoglycans. The expression of PAM1 transcripts was determined by RNA blot analysis. The mRNA was constitutively expressed in Arabidopsis roots, stems, leaves, flowers and young siliques. The expression did not change in seedlings in response to either abscisic acid, cold or high salt stress treatment. Southern blot analysis indicated that the Arabidopsis genome contains another gene highly homologous to PAM1.
Dashes indicate amino acid identity, dots indicate a gap in the protein sequence.
