-
CoTPS2 is highly expressed at the floral bud stage
additional information
Mg25 is much more evident in young developing leaf tissues than in older, more mature leaves
-
the enzyme expression increases from undeveloped small flowers to mature green flowers, is absent in mature yellow flowers, but very high in flower buds
additional information
in orange tissues, the sesquiterpene profile is qualitatively rich. Overall, up to 25 sesquiterpenes are identified in total, overview. Small amounts of beta-caryophyllene are detected in all samples, while alpha-copaene, beta-elemene, alpha-humulene, and alpha-selinene are emitted by all tissues except young leaves. Beside this, each tissue shows a characteristic sesquiterpene emission profile. Major sesquiterpenes emitted by adult leaves are beta-elemene and beta-caryophyllene, while flowers emitt nerolidol, absent from most tissues analyzed. In fruit tissues, valencene emission contributes greatly to total emitted volatiles, in much more extent in peel than in pulp
additional information
Mg25 transcript levels are low or below detection limits in tepal and carpel tissues
