The constitutive expression of HsfB2b leads to severely reduced levels of the PRR7 transcript and late flowering and elongated hypocotyls.
Title: HsfB2b-mediated repression of PRR7 directs abiotic stress responses of the circadian clock.

These data indicate that HsfB1 and HsfB2b suppress the general heat shock response under non-heat-stress conditions and in the attenuating period.
Title: Arabidopsis HsfB1 and HsfB2b act as repressors of the expression of heat-inducible Hsfs but positively regulate the acquired thermotolerance.

Data suggest that HsfB1 and HsfB2b may be involved in complex regulatory networks, which are linked to other stress responses and signaling processes.
Title: Detection of in vivo interactions between Arabidopsis class A-HSFs, using a novel BiFC fragment, and identification of novel class B-HSF interacting proteins.
