|a Temperate perennials require exposure to chilling temperatures to resume growth in the following spring. Growth and dormancy cycles are controlled by complex genetic regulatory networks and are governed by epigenetic mechanisms, but the specific genes and mechanisms remain poorly understood. To understand how seasonal changes and chilling regulate dormancy and growth in the woody perennial vine kiwifruit (Ac, Actinidia chinensis), a transcriptome study of kiwifruit buds in the field and controlled conditions was performed. A MADS-box gene with homology to Arabidopsis FLOWERING LOCUS C (FLC) was identified and characterized. Elevated expression of AcFLC-like (AcFLCL) was detected during bud dormancy and chilling. A long noncoding (lnc) antisense transcript with an expression pattern opposite to AcFLCL and shorter sense noncoding RNAs were identified. Chilling induced an increase in trimethylation of lysine-4 of histone H3 (H3K4me3) in the 5' end of the gene, indicating multiple layers of epigenetic regulation in response to cold. Overexpression of AcFLCL in kiwifruit gave rise to plants with earlier budbreak, whilst gene editing using CRISPR-Cas9 resulted in transgenic lines with substantially delayed budbreak, suggesting a role in activation of growth. These results have implications for the future management and breeding of perennials for resilience to changing climate
