1por Gallagher, Kelley A., Schumacher, Maria A., Bush, Matthew J., Bibb, Maureen J., Chandra, Govind, Holmes, Neil A., Zeng, Wenjie, Henderson, Max, Zhang, Hengshan, Findlay, Kim C., Brennan, Richard G., Buttner, Mark J.“…Here we demonstrate that c-di-GMP also intervenes later in development to control differentiation of the reproductive hyphae into spores by arming a novel anti-σ (RsiG) to bind and sequester a sporulation-specific σ factor (σ(WhiG)). We present the structure of the RsiG-(c-di-GMP)(2)-σ(WhiG) complex, revealing an unusual, partially intercalated c-di-GMP dimer bound at the RsiG-σ(WhiG) interface. …”

2por Al-Bassam, Mahmoud M., Bibb, Maureen J., Bush, Matthew J., Chandra, Govind, Buttner, Mark J.“…In contrast, Group II genes were expressed later than Group I genes and their expression depended not only on bldM but also on whiI and whiG (encoding the sigma factor that activates whiI). …”

3por Bush, Matthew J., Bibb, Maureen J., Chandra, Govind, Findlay, Kim C., Buttner, Mark J.“…Several other genes encoding proteins with important roles in development were also identified as WhiA targets, including the sporulation-specific sigma factor σ(WhiG) and the diguanylate cyclase CdgB. Cell division is tightly coordinated with the orderly arrest of apical growth in the sporogenic cell, and filP, encoding a key component of the polarisome that directs apical growth, is a direct target for WhiA-mediated repression during sporulation.…”
