The IGBB logo features a stylized "pinwheel" to the left of the letters IGBB in caps in a modified Bank Gothic Pro font.
The six-part "pinwheel" in the IGBB logo is:
- A symbol of lab unity as it shows "parts" coming together to make a "whole."
- A flower or three-leaf clover representing (a) plants, important subjects of our research, (b) life in general, and (c) the life sciences (biology).
- A set of chromosomes being moved towards the center of a cell.
- The Sun - another symbol of life.
- A protein composed of six subunits (e.g., a protein pore).
- Three foxes putting their heads together. The fox is a symbol of cleverness in Western folklore. Since the IGBB is organized into three service groups (Genomics, Proteomics/Metabolomics, and Biocomputing/Computational Biology), the foxes could represent the three disciplines working together.
- A scientist jumping for joy after making an important discovery.
- A windmill, the primary symbol associated with Cervantes' famous character Don Quixote - Like Don Quixote, scientists must be willing to attack 'wicked giants' (e.g., ignorance, racism, sexism, intolerance, use of the term 'science' in the promotion of non-scientific causes), champion worthy causes (e.g., education, intellectual freedom, human rights, environmental responsibility), and remain optimistic in the face of defeat (e.g., most days in the lab). Hopefully, however, the average scientist can accomplish these tasks without becoming delusional (a problem that squashed Quixote's dreams of becoming a plant molecular biologist).
- A DNA double-helix or protein in cross section.
- Antibodies binding to a protein.
- Whatever you want it to be.

DOWNLOAD PDFABSTRACTHistone lysine methylation is an evolutionally conserved modification involved in determining chromatin states associated with gene activation or repression. Here we report that the Arabidopsis SET domain group 8 (SDG8) protein is a histone H3 methyltransferase involved in regulating shoot branching. Knockout mutations of the SDG8 gene markedly reduce the global levels of histone H3 trimethylation at lysines 9 and 36 as well as dimethylation at lysine 36. The sdg8 mutants produce more shoot branches than wild-type plants. The expression of SPS/BUS (supershoot/bushy), a repressor of shoot branching, is decreased in sdg8 mutants, while UGT74E2 (UDP-glycosyltransferase 74E2), a gene associated with increased shoot branching, is up-regulated in sdg8 mutants. The altered expression of SPS/BUS and UGT74E2 correlates with changed histone H3 methylation at these loci. These results suggest that SDG8 regulates shoot branching via controlling the methylation states of its target genes.
