  1. BLAST analyses were performed to identify putative homologues in the indicated streptophyte algae. The number of contigs and the best e-value obtained are given.
  2. n.d. not detected, ? no clear result. 1)for most species ESTs showing similarity to several different Lea proteins were found (e.g., in Klebsormidium ESTs we detected additional sequences showing similarity to Lea14, Lea76 and Lea D29)
