LaTRE1

Gene Details:

Under P deficiency, validamycin A treatment, which inhibits trehalase, led to the accumulation of trehalose and promoted the formation of CR with enhanced organic acid production, whereas overexpression of the white lupin TREHALASE1 (LaTRE1) led to decreased trehalose levels, lateral rootlet density, and organic acid production.
Transcriptomic and virus-induced gene silencing results revealed that LaTRE1 negatively regulates the formation of CRs, at least partially, by the suppression of LaLBD16, whose putative ortholog in Arabidopsis (Arabidopsis thaliana) acts downstream of ARF7- and ARF19-dependent auxin signaling in lateral root formation.
LaTRE1 is involved in the trehalose metabolism pathway and is associated with the formation and function of CR in white lupin under P deficiency.
Overexpression of LaTRE1 leads to decreased lateral rootlet density and altered organic and amino acid metabolism.
Overall, our findings provide an association between the trehalose metabolism gene LaTRE1 and CR formation and function with respect to organic acid production in white lupin under P deficiency.
