Abstract |

内容記述 |
Flowering time in plants is regulated by a photoperiod-responsive mechanism. Some plant species use a circadian clock-based control mechanism to adapt to variable environments. Strawberry is a horticultural crop that responds to certain photoperiods and temperatures to induce flowering. However, clock-associated genes in octoploid cultivated strawberry (Fragaria × ananassa) have not been defined, and their regulatory mechanism for responding to photoperiods is unclear. We herein targeted 12 clock-associated genes reported in other plant species and performed a genome-wide analysis and expression comparison in F. × ananassa seedlings. Seventy-eight sequences were selected from the F. × ananassa genome. The major domains and cis-acting elements were conserved in each sequence. Transcripts were clearly expressed under continuous light conditions in F. × ananassa seedlings (‘Yotsuboshi’) acclimated to long days. Among them, 9 genes maintained their unique autonomous circadian rhythms and may function as clock genes. LHY (LATE ELONGATED HYPOCOTYL) had the Myb domain and LHY expression peaked in the dawn. PRR (PSEUDO-RESPONSE REGULATOR) family members (PRR9, PRR7, PRR5, and TOC1 (TIMING OF CAB EXPRESSION 1)) had a pseudo-receiver domain and CCT domain, and peak expression times began sequentially from the afternoon for PRR9 to the evening for TOC1. LUX (LUXARRHYTHMO) had a Myb domain, and LUX expression peaked in evening with ELF3 (EARLY FLOWERING 3). FKF1 (FLAVIN-BINDING KELCH REPEAT F BOX 1) had PAS and F-box domains, and FKF1 expression peaked in the afternoon. GI (GIGANTEA) expression also peaked in the afternoon. F. × ananassa (‘Yotsuboshi’) appears to have multiple feedback loops comprising clock-associated genes. Although the rhythmic expression of CHE (CCA1 HIKING EXPEDITION) and ZTL (ZEITLUPE) was not observed, they had conserved domains, CHE with the TCP domain and ZTL with the PAS and F-box domains. The present results provide basic information on the circadian clock for the control of F. × ananassa flowering. |
