Pistachio is a nut crop domesticated in the Fertile Crescent and a dioecious species with ZW sex chromosomes. We sequenced the genomes of Pistacia vera cultivar (cv.) Siirt, the female parent, and P.
The study focuses on the cultivated strawberry, which has been the subject of increased genetic research, specifically looking at sucrose metabolism in two varieties: 'Rubygem' and 'Fortuna'.
The research examines fruit development stages (red, pink, green, and white), finding red fruits contained the highest sugar content while green fruits had the lowest; overall sugar levels were similar between varieties.
The study reveals a positive correlation between sugar content and invertase enzyme activity, but a negative correlation between enzyme activity and gene expression, with the lowest invertase activities observed in green fruits.
