Expression analysis of CsINV5 during CA periods in 2015–2016 and 2016–2017 and under different sugar and temperature conditions. a Changes in air temperature from October 2016 to March 2017. The maximum (Max), average (Avg) and minimum (Min) daily temperatures are shown. The red arrows indicate the Avg temperature of each sampling day. b-c Expression analysis of CsINV5 in the mature leaves of four-tea cultivars during cold acclimation periods in 2015–2016 and 2016–2017 by using qRT-PCR. The expression pattern of CsINV5 in different tea cultivars was showed with different color lines. d Expression analysis of CsINV5 in the leaves of tea plant cultivar ‘LJ43’ under different sugar and temperature conditions by using qRT-PCR. ‘CK’ represents the sugar deficiency control, ‘n’ represents the normal temperature, ‘c’ represents the 4 °C treatment, ‘re’ represents the temperature recovered to normal level. All results were calculated by using the 2–ΔCt method with CsPTB as housekeeping gene. Data are shown as the means ± SE (n = 3)
