Global transcriptome dissection of pollen-pistil interactions induced self-incompatibility in dragon fruit (.

Self-incompatibility (SI) is a major issue in dragon fruit () breeding and production. Therefore, a better understanding of the dragon fruit SI mechanism is needed to improve breeding efficiency and ultimate production costs. To reveal the underlying mechanisms of SI in dragon fruit, plant anatomy, RNA sequencing-based transcriptomic analysis, and multiple bioinformatic approaches were used to analyze gene expression in the pistils of the self-pollinated and cross-pollinated dragon fruit flowers at different intervals of time after pollination.

Metabolomics and Transcriptomics Analysis of Pollen Germination Response to Low-Temperature in Pitaya ().

Cross-pollination can improve the percentage of fruit set and fruit weight for most red flesh varieties in pitaya. The technology of pollen storage was very important for successful cross-pollination. However, till present, the technology of pollen storage is unsatisfactory in pitaya production.
