Endophytic Bacterium RG11 May Transform Tryptophan to Melatonin and Promote Endogenous Melatonin Levels in the Roots of Four Grape Cultivars.

Endophytes have been verified to synthesize melatonin and promote abiotic stress-induced production of endogenous melatonin in grape ( L.) roots. This study aimed to further characterize the biotransformation of tryptophan to melatonin in the endophytic bacterium RG11 and to investigate its capacity for enhancing endogenous melatonin levels in the roots of different grape cultivars.

Transcriptome analysis of genes involved in anthocyanins biosynthesis and transport in berries of black and white spine grapes ().

Background: The color of berry skin is an important economic trait for grape and is essentially determined by the components and content of anthocyanins. The fruit color of Chinese wild grapes is generally black, and the profile of anthocyanins in Chinese wild grapes is significantly different from that of . However, is the only species that possesses white berry varieties among Chinese wild grape species.

Genetic diversity assessment of Bge. populations from Henan province of China by SRAP markers.

Eighteen sequence-related amplified polymorphism (SRAP) primer combinations were used to assess the genetic diversity of 126 individuals from five different geographical populations of Bge. The numbers of bands scored per primer combination ranged from 8 to 27, with an average of 18.6 bands.
