Acclimation of circadian rhythms in woodland strawberries (Fragaria vesca L.) to Arctic and mid-latitude photoperiods
Background Though many abiotic factors are constantly changing, the photoperiod is a predictable factor that enables plants to time many physiological responses. This timing is regulated by the circadian clock, yet little is known about how the clock adapts to the differences in photoperiod between...

The primary objective of this study was to compare how clock gene expression is modified in four woodland strawberry (Fragaria vesca L.) accessions originating from two different populations in Italy (IT1: Tenno, Italy, 45(degrees)N, IT4: Salorno, Italy, 46(degrees)N) and two in Northern Norway (NOR2: Alta, Norway, 69(degrees)N, NOR13: Indre Nordnes, Norway 69(degrees)N) when grown under simulated daylength conditions of an Arctic or mid-latitude photoperiod.

Free-running rhythms for FvLHY in IT1 and IT4 were higher after the Arctic photoperiod, while the free-running rhythm for FvLUX in IT4 was higher after the mid-latitude photoperiod. IT1 showed significantly higher expression of FvLHY and FvPRR9 than all other accessions, as well as significantly higher expression of the circadian regulated phytohormone, abscisic acid (ABA), but low levels of salicylic acid (SA).

Background Though many abiotic factors are constantly changing, the photoperiod is a predictable factor that enables plants to time many physiological responses.
