The present work is emphasised with the herbicidal tolerance of Azolla pinnata R.Br. and its modulation with TiO
2
nano-particle. Both carbohydrate and nitrogen metabolism were effected with 2,4-D as herbicide and in few cases TiO
2
-NP had recovered few detrimental effects. From the nutrient status in Azolla it recorded the recovery of nitrogen as well as potassium by TiO
2
-NP but not in case of phosphorus. However, a conversion of
nitrate
to ammonium was more induced by TiO
2
-NP under herbicidal toxicity. Similar results were obtained for inter-conversion of amino acid-
nitrate
pool, but no changes with glutamine synthase activity with TiO
2
-NP. Initially, the effects of 2,4-D was monitored with changes of chlorophyll content but had not been recovered with nanoparticle. Photosynthetic reserves expressed as both total and reducing sugar were insensitive to TiO
2
-NP interference but activity of soluble and wall bound invertase was in reverse trend as compared to control. The 2,4-D mediated changes of redox and its oxidative stress was ameliorated in plants with over expressed
ADH
activity. As a whole the Azolla bio system with TiO
2
supplementation may be useful in sustenance against 2,4-D toxicity through recovery of nitrogen metabolism. Thus, Azolla-TiO
2
-NP bio system would be realised to monitor the herbicidal toxicity in soil and its possible bioremediation.

During cold stress, soybean CBF/DREB1 transcript levels increase rapidly; however, expected downstream targets appear unresponsive. Here, we asked whether the ethylene signaling pathway, which is enhanced in the cold can negatively regulate the soybean CBF/DREB1 cold responsive pathway; thus contributing to the relatively poor cold tolerance of soybean. Inhibition of the ethylene signaling pathway resulted in a significant increase in
GmDREB1A;1
and
GmDREB1A;2
transcripts, while stimulation led to decreased
GmDREB1A;1
and
GmDREB1B;1
transcripts. A cold responsive reporter construct (
AtRD29A
prom
::GFP/GUS
), as well as predicted downstream targets of soybean CBF/DREB1 [
Glyma.12g015100
(
ADH
),
Glyma.14g212200
(ubiquitin ligase),
Glyma.05g186700
(AP2), and
Glyma.19g014600
(CYP)] were impacted by the modulation of the ethylene signaling pathway. Photosynthetic parameters were affected by ethylene pathway stimulation, but only at control temperatures. Freezing tolerance (as measured by electrolyte leakage), free proline, and MDA; in both acclimated and non-acclimated plants were increased by silver
nitrate
but not by other ethylene pathway inhibitors. This work provides evidence that the ethylene signaling pathway, possibly through the action of EIN3, transcriptionally inhibits the CBF/DREB1 pathway in soybean.
