Dietzia natronolimnaea
STR1 protecting wheat plants from salt stress by modulating the transcriptional machinery responsible for salinity tolerance in plants. The expression studies confirmed the involvement of ABA-signalling cascade, as
TaABARE
and
TaOPR1
were upregulated in PGPR inoculated plants leading to induction of
TaMYB
and
TaWRKY
expression followed by stimulation of expression of a plethora of stress related genes. Enhanced expression of
TaST
, a salt stress-induced gene, associated with promoting salinity tolerance was observed in PGPR inoculated plants in comparison to uninoculated control plants. Expression of SOS pathway related genes (
SOS1
and
SOS4
) was modulated in PGPR-applied wheat shoots and root systems. Tissue-specific responses of ion transporters
TaNHX1
,
TaHAK
, and
TaHKT1
, were observed in PGPR-inoculated plants. The enhanced gene expression of various antioxidant enzymes such as
APX
,
MnSOD
,
CAT
,
POD
,
GPX
and
GR
and higher proline content in PGPR-inoculated wheat plants contributed to increased tolerance to salinity stress. Overall, these results indicate that halotolerant PGPR-mediated salinity tolerance is a complex phenomenon that involves modulation of ABA-signalling, SOS pathway, ion transporters and antioxidant machinery. |
