A method for the production of plants with altered photorespiration and improved CO2 fixation

Ref.-Nr.: 0706-5666-IKF

Prozesse und Methoden (inkl. Screening) : Lebens-Wissenschaften (inkl. Screening)
Grüne Biotechnologie

Recently, many efforts have been made to improve growth and yield of crop plants. CO2 fixation in plants is primarily catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase (Rubisco). The inherent inefficiency of Rubisco necessitates an additional metabolic process termed photorespiration, which results in the loss of carbon and energy. In fact, it has been estimated that plants lose approximately 25% of the fixed carbon due to photorespiration. Despite several attempts to improve ...

The cellular identity of mature cells that are confined in a specialized genetic expression profile can be overcome by introducing just a few genes that encode for so-called reprogramming factors [1]. By means of this intervention, also known as reprogramming, the cells then become pluripotent and represent induced pluripotent stem cells (iPS cells) [1]. Nowadays, numerous new cell culture models have been established based on reprogramming protocols that yield iPS cells. Such cell culture models ...

Precise genome editing demands for homology-directed repair (HDR) by aiming to introduce a new double stranded DNA substituting for a homologous sequence but partially defect one. This substrate dependent reaction does compete with direct non-homologous end joining (NHEJ) of the double strand breaks. NHEJ is error-prone and is therefor mainly used for gene inactivation.
The rate of NHEJ is directly limiting the rate of HDR. For this reason HDR in vitro does occur on a very low level only and ...
