The introduction of the ACC deaminase activity within M. loti in a constitutive way could be a novel strategy to increase nodulation competitiveness of the bacteria, which could be useful for the forage inoculants industry.
Phloem sugars and amino acids as potential regulators of hordein expression in field grown malting barley (Hordeum vulgare L.)

The results suggest that the sharp fall in isopentenyl adenosine concentration could be the earliest event that induces protein degradation during the development of senescence induced by N deficiency, and that only later is ABA accumulated and oxidative stress developed.

It is concluded that root plasticity could be part of the general mechanism of L. glaber salt tolerance only in the case of non-symbiotic plants.

Spermidine and spermine contributed the most with the salt-induced root polyamine increment observed upon salinization in roots of nodulated plants, suggesting that these polyamines might mediate an adaptive role of the plant–M.
Subtilase activity and gene expression during germination and seedling growth in barley.
Glomus intraradices improved salt tolerance in Prosopis alba seedlings by improving water use efficiency and shoot water content
The results suggest that inoculation with G. intraradices improves P. alba survival rates during the implantation period and seems to be a promising strategy to improve P.Alba cultivation in saline lands.
Arbuscular Mycorrhizal Pecan Seedlings Alleviate Effect of Restricted Water Supply
This poster presents a probabilistic model of the response of the immune system to the presence of foreign substances, using a variety of natural and synthetic substances.
