Register now for the Leibniz Symposium on Plant Cell Walls

Debora Gasperini, Katharina Bürstenbinder and Catalin Voiniciuc are co-organizing the Leibniz Plant Biochemistry Symposium 2021. This annual conference will be focused on Plant Cell Walls this year, and will be held as an online event for the first time.

We have an exciting speaker line-up and there will be free registration for participants from around the world. Space is limited, so don’t miss out.

February publication update

We are happy to have contributed to a new publication that appeared in Science Advances on the February 10. This study unveils how jasmonate signaling is initiated in the korrigan1 (kor1) cellulose-deficient mutant, and multiple ways in which it can be complemented. The work was lead by Stefan Mielke in Debora Gasperini’s research group at IPB Halle.

Catalin Voiniciuc performed the cell wall analyses, and would like to acknowledge the valuable technical assistance of Christine Wagner and Bo Yang. The Science Advances study was originally available as a pre-print:

February also marks the release of a correction to the Voiniciuc et al. (2018) Plant Physiology study of pectin biosynthetic enzymes. Unfortunately, there was an accidental mix-up of GAUT11 and another GAUT protein expressed at the same time. Catalin would like to thank the co-authors for reporting the problem affecting Figure 5 and Supplemental Figure 4A, and repeating the experiments. The corrigendum has addressed this issue and shows that the original results and conclusions that GAUT11 is a galacturonosyltransferase (GalAT) that elongates homogalacturonan (HG) are unaffected.

Review of orthogonal hosts to study cell wall synthesis

We published a review article in Plants (https://doi.org/10.3390/plants8110516), part of a special issue on “Plant Cell Wall Biology”. In close collaboration with multiple colleagues from Düsseldorf, we assessed the suitability of more than ten orthogonal hosts for synthetic biology and to study plant cell wall biosynthesis.

In particular, we focused on the key advantages and limitations of several bacterial, fungal and animal systems for the heterologous expression of plant glycosyltransferases to reconstruct polymers. We also analyzed the glycosidic linkages of native polymers from promising orthogonal hosts and discuss how they might impact the heterologous production of various plant polysaccharides.
