Cryptic bacterial pathogens of diatoms peak during senescence of a winter diatom bloom

L. Branscombe, E. L. Harrison, C. Zhi Yi, M. Keys, C. Widdicombe, W. H. Wilson, M. Cunliffe, K. E. Helliwell

The paper identifies cryptic bacterial pathogens of diatoms that peak during winter blooms, revealing their role in influencing diatom populations and bloom dynamics.

Cold-induced cyt elevations function to support osmoregulation in marine diatoms

F. H. Kleiner, K. E. Helliwell, A. Chrachri, A. Hopes, H. Parry-Wilson, T. Gaikwad, N. Mieszkowska, T. Mock, G. L. Wheeler, C. Brownlee

This study shows that cold-induced cytosolic calcium elevations in diatoms support osmoregulation during simultaneous cold and hypo-osmotic stress.

Physiological and molecular responses of a newly evolved auxotroph of Chlamydomonas to B12 deprivation

F. Bunbury, K. E. Helliwell, P. Mehrshahi, M. P. Davey, D. L. Salmon, A. Holzer, N. Smirnoff, A. G. Smith

This study examines the physiological and molecular responses of a newly evolved B12-dependent mutant of Chlamydomonas to B12 deprivation and shows that co-culturing with B12-producing bacteria improves survival and B12 use-efficiency.
