Weeds are a severe threat to global food production. Many weeds use the C4 photosynthetic pathway, while the majority of crop plants use C3 photosynthesis. Work in our lab has identified selective inhibitors of PEP Carboxylase, a key enzyme involved in carbon fixation in the C4 pathway. Further studies on whole plant level and microbial growth studies confirm the selective effect on C4 plants, whereas C3 plants and selected soil bacteria are not affected by these substances. Recent structural work on Pyruvate Phosphate Dikinase, another essential enzyme of the C4 pathway, has resolved yet unknown conformational intermediates in the catalytic cycle of this multi-domain molecular machine which is thought to perform one of the largest single domain movements in proteins. Building on these structures and small molecule library screening, we have identified further potent inhibitors of the C4 pathway which are among the most effective PPDK inhibitors known today. Further research aims at reducing post-harvest losses and food waste. Work in our lab has uncovered a novel way to control fruit ripening by inhibiting essential protein-protein interactions in the signaling pathway of the plant hormone ethylene. Peptides masking these interactions were shown to affect ethylene responses in planta. Considering the high level of conservation in the ethylene pathway such peptide biologicals may contribute to the development of a novel family of ripening inhibitors and innovative ripening control in climacteric fruit.
- August 2016 – A new paper on Peptides interfering with essential protein-protein interactions in the ethylene signaling pathway causing fruit ripening delay by Prof. Georg Groth has been published in Scientific Reports and has been reported on local newspaper, radio, television and online by Informationsdienst Wissenschaft (idw), German Life Sciences Association (VBIO) and German Society for Plant Sciences (DBG).
