| Abstrak/Abstract |
Strawberries are non-climacteric fruits and highly demanded for its distinctive flavor and aroma, as well as its benefits as a cancer preventive. The ripening of strawberry fruits is regulated by abscisic acid (ABA). Through the ABA signaling pathway involving receptor proteins, protein phosphatases and protein kinases, ABA will activate the fruit ripening genes. One of the ABA receptor genes is FaPYR. Increased expression of FaPYR1, followed by the expression of fruit ripening genes such as FaCHS, which encodes the enzyme for the synthesis of anthocyanin, indicates that the ripening of strawberry fruits has begun. The purpose of the present study was to study the role of the expression of FaPYR1 and FaCHS in the ripening of strawberry fruits. The present study analyzed the level of expression of FaPYR1 and FaCHS using Real-Time Polymerase Chain Reaction (RT-qPCR) on two species of strawberry plants, Fragaria x ananassa ‘Festival’ and Fragaria vesca ‘Californica’ obtained from Banyuroto Agrotourism, Magelang, Central Java. Results showed that FaPYR1 and FaCHS played a role in the ripening of strawberries, but within a different duration. FaPYR1 was expressed at a higher level in the pink stage, while FaCHS was expressed higher in the red stage, both on the Californica and Festival cultivars. |
