polar transport मीनिंग इन हिंदी

Together, this indicates that PIN-mediated auxin polar transport plays a central role in flower initiation at the shoot apical meristem.
Overall, auxin polar transport plays a central role in the spatio-temporal control of organ initiation and in tissue patterning in plants.
Many external and internal signals ( e . g . blue light, mechanical stress, gravity or cytokinins ) can interfere with PIN protein polarity and therefore with the directionality of auxin polar transport.
For long distances, relocation occurs via the stream of fluid in phloem vessels, but, for short-distance transport, a unique system of coordinated polar transport directly from cell to cell is exploited.
