| additional information | introduction of the trehalose biosynthesis pathway without producing trehalose 6-phosphate as an intermediate in plants: construction of a gene that encodes a bifunctional in-frame fusion (BvMTSH) of maltooligosyltrehalose synthase (BvMTS) and maltooligosyltrehalose trehalohydrolase (BvMTH) from the nonpathogenic bacterium Brevibacterium helvolum to avoid growth inhibition by trehalose 6-phosphate in transgenic Oryzsa sativa subsp. japonica cv. Nakdong plants. Transgenic rice plants that overexpress BvMTSH under the control of the constitutive rice cytochrome c promoter (101MTSH) or the abscisic acid-inducible Ai promoter (105MTSH) show enhanced drought tolerance without growth inhibition, as well as an abscisic acid-hyposensitive phenotype in the roots, overview | Brevibacterium helvolum |

|---|---|---|
| metabolism | biosynthesis of trehalose is mediated by maltooligosyltrehalose synthase and maltooligosyltrehalose trehalohydrolase. In this pathway, trehalose 6-phosphate is not generated as an intermediate | Brevibacterium helvolum |
