Red dragon fruit or red pitaya (Hylocereus polyrhizus) is the only edible fruit that contains betalains. The color of betalains ranges from red and violet to yellow in plants. Betalains may also serve as an important component of health-promoting and disease-preventing functional food. Currently, the biosynthetic and regulatory pathways for betalain(More)
An efficient propagation system of pitaya with diverse genetic background was established by using tender stem as explants. Various types of plant growth regulators (PGRs) were used to determine the most effective hormone combination for shoot proliferation. Zeatin (ZT), thidiazuron (TDZ), 2, 4-dichlorophenoxyacetic acid (2, 4-D) and 6-benzylaminopurine(More)
We investigated the effect of water stress on yield and quality of tomato plants overexpressing Solanum lycopersicum thylakoid-bound ascorbate peroxidase gene (StAPX). APX activity, hydrogen peroxide content, net photosynthetic rate of tomato leaves, and yield and nutrition quality of tomato fruits were measured under soil moisture 70, 60, and 50 % of full(More)
