Description Increasing concentration of glucose not only controls root length, root hair and number of lateral roots
but can also modulate root growth direction. Since root growth and development is also controlled by auxin, whole
genome transcript profiling was done to find out the extent of interaction between glucose and auxin response pathways.
Glucose alone could transcriptionally regulate 376 (62%) genes out of 604 genes affected by IAA. Presence of glucose could
also modulate the extent of regulation 2 fold or more of almost 63% genes induced or repressed by IAA. Interestingly,
glucose could affect induction or repression of IAA affected genes (35%) even if glucose alone had no significant effect on
the transcription of these genes itself. Glucose could affect auxin biosynthetic YUCCA genes family members, auxin
transporter PIN proteins, receptor TIR1 and members of a number of gene families including AUX/IAA, GH3 and SAUR
involved in auxin signaling. Arabidopsis auxin receptor tir1 and response mutants, axr2, axr3 and slr1 not only display a
defect in glucose induced change in root length, root hair elongation and lateral root production but also accentuate
glucose induced increase in root growth randomization from vertical suggesting glucose effects on plant root growth and
development are mediated by auxin signaling components.
