Morphological and metabolic changes in Changshan Huyou (Citrus changshan-huyou) following natural tetraploidization.

ABSTRACT:

Background

Polyploids in citrus are generally used to improve crop varieties. Changshan Huyou (Citrus changshan-huyou) is a native citrus species in China that is highly adaptable and has pharmaceutical value. However, the influence in Changshan Huyou following polyploidization remains unclear. Here we evaluated the adult tetraploid scions of Changshan Huyou with contemporary diploid scions as the control in the phenotypic variations, metabolic alterations of fruits and associated transcriptomic changes.

Result

The tetraploid scions had rounder and thicker leaves, larger floral organs and fruits, and satisfactory viability of pollen grains and ovules. The tetraploid fruits accumulated lower levels of soluble solids but similar levels of organic acids. Metabolic profiling of
