A molecular marker for identifying allelic variations of a soluble acid invertase gene AcoInv-1 in pineapple fruits and application thereof
The present application relates to the field of agricultural biotechnology, and particularly relates to a molecular marker capable of identifying allelic variations of a soluble acid invertase gene AcoInv-1 in pineapple fruits and application thereof. The molecular marker is amplified by using the following primers: forward primer 5-CTGCGAAATGAACTAGTCAACTC-3 and reverse primer 5-TAGAGAACCGTTCTTGG AATGG-3. The primers can identify allelic variations of the soluble acid invertase gene AcoInv-1 in pineapple fruits, i.e. AcoInv-1a and AcoInv-1b. It is found through research that the two allelic variations are extremely significantly related to the total sugar content of the pineapple fruits. It is proved through verification that the pineapple material of the AcoInv-1a type is related to high sugar content, and the pineapple material of the AcoInv-1a and AcoInv-1b types is related to low sugar content. The application of the molecular marker obtained by the present application in selecting pineapple varieties with high sugar content potential will help to accelerate the breeding selection cycle.

A molecular marker for identifying allelic variations in the AcoInv-2 gene, a soluble acid invertase gene in pineapple fruit, and its application.
This invention relates to the field of agricultural biotechnology, specifically to a molecular marker and its application for identifying allelic variations of the soluble acid invertase gene AcoInv-2 in pineapple fruit. This molecular marker is amplified using the following primers: forward primer: 5-AGCGAGCACGCCGACATCC-3, reverse primer: 5-CGTCTATATTTGAGGACGACTAGT-3. These primers can identify the allelic variation types of the soluble acid invertase gene AcoInv-2 in pineapple fruit: AcoInv-2a and AcoInv-2b. Studies have shown that both allelic variation types are significantly correlated with the total sugar content of pineapple fruit. Verification has demonstrated that pineapple materials with the AcoInv-2a type are associated with high sugar content, while pineapple materials with both AcoInv-2a and AcoInv-2b types are associated with low sugar content. The application of the molecular marker obtained in this invention in selecting pineapple varieties with high sugar content potential will help accelerate the breeding selection cycle.
