  abstract = {{G}eneral transcription factor {IIB} ({TFIIB}) and {TFIIB}-related factor ({BRF}), are conserved {RNA} polymerase {II}/{III} ({RNAPII}/{III}) selectivity factors that are involved in polymerase recruitment and transcription initiation in eukaryotes. {R}ecent findings have shown that plants have evolved a third type of {B}-factor, plant-specific {TFIIB}-related protein 1 (p{BRP}1), which seems to be involved in {RNAPI} transcription. {H}ere, we extend the repertoire of {B}-factors in plants by reporting the characterization of a novel {TFIIB}-related protein, plant-specific {TFIIB}-related protein 2 (p{BRP}2), which is found to date only in the {B}rassicacea family. {U}nlike other {B}-factors that are ubiquitously expressed, {PBRP}2 expression is restricted to reproductive organs and seeds as shown by {RT}-{PCR}, immunofluorescence labelling and {GUS} staining experiments. {I}nterestingly, pbrp2 loss-of-function specifically affects the development of the syncytial endosperm, with both parental contributions required for wild-type development. p{BRP}2, is the first {B}-factor to exhibit cell-specific expression and regulation in eukaryotes, and might play a role in enforcing bi-parental reproduction in angiosperms.},
