“…Since then, relatively abundant annexins have been identified and isolated from a number of plants (Smallwood et al, 1990;Blackbourn et al, 1992;Clark et al, 1992;Andrawis et al, 1993). Although the general functions of plant annexins are still in question (for review, see Clark and Roux, 1995;Delmer and Potikha, 1997), recent isolation of partial or complete annexin cDNA clones from higher plants, including monocots (Battey et al, 1996) and dicots (Pirck et al, 1994;Gidrol et al, 1996;Proust et al, 1996;Potikha and Delmer, 1997), provides some insight into the structural characteristics of plant annexins. The endonexin repeats found in animal annexins are also observed in plant annexins; however, it seems that plant annexins contain fewer predicted Ca 2ϩ -binding sites than animal annexins (see Clark and Roux, 1995).…”
