Abstract: The invention relates to a method for changing the development pattern, increasing the growth and starch accumulation, changing the structure of starch and increasing the resistance to water stress in plants. The method involves culturing plants in an atmosphere containing volatile elements emitted by a microorganism, without there being any physical contact between the microorganism and the plant. The method is based on the discovery that the volatile elements emitted by Gram-positive or Gram-negative bacteria, yeasts and microscopic fungi stimulate an increase in the growth of plants in general, with an increase in the height, the number of leaves and/or the number of branches of the plant, as well as an increase in the accumulated starch and structural change of this biopolymer, and modification of the development pattern, with an increase in floral buds. An increased resistance to water stress can also be observed, in addition to an increase in starch in leaves separated from whole plants.

Abstract: The present invention describes bacterial strains CECT 7968, CECT 7969 and NCIMB 42026 of the species B. subtilis, capable of expressing the heterologous synthetic mutated genes: pdc and adhB, originating from Z. mobilis, 'tesA, originating from E. coli, and atfl, originating from Acinetobacter sp. ADP1. Furthermore, said strains may overexpress at least one of the genes of the ACC (acetyl-CoA carboxylase) and acyl-CoA synthetase enzymatic complexes. The use of said strains produces an increase in the production of biofuel, preferably biodiesel from glycerin as the carbon source. Moreover, the present invention describes the use of said bacterial strains for the production of said biofuel, biodiesel, from glycerin, as well as a process for synthesising biofuel, preferably biodiesel, using the strains described in the present invention and the biofuel duly obtained.

Abstract: A process for the production of transgenic plants that have a high starch content and yield and a high amylose/amylopectin ratio. The alpha-1,4-glucan phosphorylases (GPs) catalyze the reversible cutting of bonds ?-1,4 of the non-reducing ends of homopolysaccharides with at least 5 glucose molecules such as starch, maltodextrin and glycogen, leading to production of glucose-1-phosphate. The GPs in bacteria and animal cells are responsible for the breakdown of glycogen. Although the increase in GP activity leads to a reduction in intracellular levels of glycogen in bacteria and animal cells, this invention discloses the production of plants that have high starch levels and yields and high amylose/amylopectin ratio, as result of the expression of genes coding for GPs.
