Previously, we reported that mitochondria-associated hexokinases are active in controlling
programmed cell death in plants (Plant Cell 18, 2341-2355). Here, we investigated their role …

Sequencing data from 10 species show that a plant hexokinase (HXK) family contains 5–11
genes. Functionally, a given family can include metabolic catalysts, glucose signaling …

Background Hexokinase catalyzes the phosphorylation of glucose and fructose, but it is also
involved in sugar sensing in both fungi and plants. We have previously described two types …

Sugars are key regulatory molecules that affect diverse processes in higher plants.
Hexokinase is the first enzyme in hexose metabolism and may be a sugar sensor that …

The hypersensitive response (HR) is a powerful resistance system that plants have
developed against pathogen attack. There are two major pathways for HR induction; one is …

Previous studies have revealed a central role of Arabidopsis thaliana hexokinases (AtHXK1
and AtHXK2) in the glucose repression of photosynthetic genes and early seedling …

Oxalate oxidase (OXO) converts oxalic acid (OA) and O2 to CO2 and hydrogen peroxide
(H2O2), and acts as a source of H2O2 in certain plant-pathogen interactions. To determine if …

Hexokinase (HXK) is present in all virtually living organisms and is central to carbohydrate
metabolism catalysing the ATP‐dependent phosphorylation of hexoses. In plants, HXKs are …

Background To survive in a changing environment plants constantly monitor their
surroundings. In response to several stresses and during photorespiration plants use …

Plant hexokinases (HXKs) are a class of multifunctional proteins that not only act as the
enzymes required for hexose phosphorylation but also serve as sugar sensors that repress …
