Wall-bound proteins of pollen tubes after self- and cross-pollination in Lilium longiflorum

Wall-bound proteins of Lilium longiflorum pollen tubes grown in vivo constitute 20–27% of the dry matter. Twenty-two-twenty-six percent of these proteins are NaCl soluble. Wall-bound proteins of in vivo pollen tubes are present in amounts 5–7 times that found in tubes grown in vitro. The protein pattern of wall-bound proteins is different between in vitro… (More)
