Proposed models of CsA-IPT5 transcripts in the regulation of shoot branching in tea plant. A A proposed model of CsA-IPT5 transcripts in the regulation of shoot branching induced by exogenous 6-BA application in tea plant. B A proposed model of CsA-IPT5 transcripts in the regulation of shoot branching induced by the second pruning in tea plant. Each shoot branching process regulated by CsA-IPT5 transcripts are included in a single rectangle composed by brown dashed lines, respectively. Black dashed arrows represent exogenous 6-BA spraying. Black dashed lines represent the second pruning. Light blue ellipses represent the transported CTKs. Blue rectangles represent locally biosynthetic CTKs. Black arrows represent activation. Light blue solid arrows represent transportation, whereas light blue dashed arrows represent long-distance transportation.
