Achromobacter sp. FB-14 mediated morpho-physio-biochemical and molecular improvements in cotton subjected to salt stress.

ABSTRACT:

Background

Cotton is considered moderately salt-tolerant, yet the degree of tolerance can vary significantly among different genotypes.

Methods and results

The current study examined the effects of plant growth-promoting bacterium "Achromobacter sp. FB-14" in two cotton genotypes (FH-326 and FH-941). Under 150 mM salt stress, FH-941 showed a higher accumulation of malondialdehyde (MDA) and hydrogen peroxide (H₂O₂) i.e. 24.4 and 8.20 µmol g^- 1 FW, respectively. Contrarily, FH-326 exhibited higher catalase (CAT) and peroxidase (POD) activities (48.82 & 27.81 Umg^- 1 protein, respectively). FB-14 inoculated plants exhibited an increase in chlorophyll a content by 10% (FH-326) and 8% (FH-941). FH-326 exhibited better ion (Na⁺
