Effect of trehalose on growth and stress tolerance in crops by using bioinoculants

Resumo

Trehalose biosynthetic is an an important pathway that linked to abiotic stress tolerance. Recent research findings showed that the trehalose metabolic pathway is important for the growth and development of the plant. In plants, trehalose production seemed to be exclusively reserved for stress resistant plants which living in extreme habitats. In variety of plant species to improve the stress tolerance and yield particularly under stress condition, several attempts to engineer plants that produce more trehalose.  In many studies have observed the regulatory role of trehalose-6-phosphate, a precursor of trehalose, play an important role in sugar metabolism, growth and development in plants. Trehalose-6-phosphate influences the starch and sucrose accumulation in leaves during day time regulates starch degradation at night to demand for sucrose. It is necessary to understand about the potential role of trehalose as a metabolite in abiotic stress responses and interactions of plants with bacterial and fungal pathogens, rhizobia, mycorrhizae and non symbiotic rhizobacteria.
