cotyledon enzyme form MsrB2 is detectable in the embryonic axes and in cotyledons Acer platanoides
-
seed enzyme form MsrB2 is detectable in the embryonic axes and in cotyledons. A greater amount of MsrB2 is revealed in embryonic axes at the 14th weeks after flowering (WAF). The two redox MsrB2 forms (two different redox forms with molecular masses of 12000 Da and 13000 Da) are revealed in cotyledons at the 12th-16th WAF. During later stages, the 12000 Da form is hardly detectable in the cotyledons, and the protein abundance decreases. Higher abundance of reduced MsrB2 during the first stages of seed formation Acer platanoides
-
seed in embryonic axes, detectable amounts of the enzyme form MsrB1 are revealed at the 13th weeks after flowering (WAF). In cotyledons, MsrB1 is detectable one week earlier, and the protein is present in larger amounts throughout the whole development and during the maturation phase. Linear increase in the amount of the enzyme form MsrB1 at the 12th-17th WAF in cotyledons. Increased abundance of enzyme form MsrB1 at the 15th-17th WAF in embryonic axes. MsrB2 is detectable in the embryonic axes Acer pseudoplatanus
