Article Synopsis
  • The study demonstrates the role of the Hik8-cascade in regulating gene expression related to glycolytic and oxidative pentose phosphate (OPP) pathways in Synechocystis under glucose plus light conditions.
  • Hik8 enhances the expression of key glycolytic genes like fbaA via another gene, sll1330, indicating a complex signal transduction system impacting glucose breakdown and energy production.
  • Disruption mutants of Hik8 and sll1330 were used to show that this signaling pathway upregulates various glycolytic genes and suggests that another histidine kinase, sll1334, may act as a negative regulator in the cascade.

Haematococcus pluvialis is a freshwater species of green algae and is well known for its accumulation of the strong antioxidant astaxanthin, which is used in aquaculture, various pharmaceuticals, and cosmetics. High levels of astaxanthin are present in cysts, which rapidly accumulate when the environmental conditions become unfavorable for normal cell growth. It is not understood, however, how accumulation of high levels of astaxanthin, which is soluble in oil, becomes possible during encystment.
