Growth, antioxidant enzyme activity and transcriptome response to low-temperature induction of flowering in cultivated strawberry
This study aimed to investigate the impact of low-temperature treatment on growth, antioxidant enzyme activity, flowering physiology and transcriptome change of the cultivated strawberry, cultivar 'Baiyu'. By comparison with the plants just before treatment (at day 0), it was shown that during the 15-day low temperature treatment, plant height, leaf area, and dry weight significantly, amino acid and soluble sugar contents all decreased with concurrent calyx formation, while the levels of MDA, activities of SOD and CAT increased significantly. Flower bud differentiation began before day 5, as evidenced by significant upregulation in expression of several known flower -related genes including FaAP1, FaSVP, FaCO1, and FaLFY.
