Auxin flow-mediated anatomical modifications in Indian Meso–Cenozoic plants

TLDR: The present investigation records the evidence of such disrupted polar auxin flow in the form of auxin whirlpool in fossil woods of Tracheidoxyl, Ailanthoxylon indicum and Calophylloxylon sp.

Abstract: Polar transport of the phytohormone auxin is a well-known physiological phenomenon recorded in different extant plant groups including bryophytes and pteridophytes. Earlier, this phenomenon has bee...
