  abstract = {{T}he recent sequence analysis of the photosynthetic and plant-symbiotic {B}radyrhizobium sp. strain {BTA}i1 revealed the unexpected presence of a puc{BA} operon encoding the apoproteins of peripheral light-harvesting ({LH}) complexes. {T}his puc{BA} operon is found close to a bacteriophytochrome gene ({B}ph{P}3({B}) ({BTA}i1)) and a two-component transcriptional regulator gene ({TFBTA}i1 gene). {I}n this study, we show that {B}ph{P}3{B} {BTA}i1 acts as a bona fide bacteriophytochrome and controls, according to light conditions, the expression of the puc{BA} operon found in its vicinity. {T}his light regulatory pathway is very similar to the one previously described for chromo-{B}ph{P}4({R}p) in {R}hodopseudomonas palustris and conducts the synthesis of a peripheral {LH} complex. {T}his {LH} complex presents a single absorption band at low temperature, centered at 803 nm. {F}luorescence emission analysis of intact cells indicates that this peripheral {LH} complex does not act as an efficient light antenna. {O}ne putative function of this {LH} complex could be to evacuate excess light energy in order to protect {B}radyrhizobium strain {BTA}i1, an aerobic anoxygenic photosynthetic bacterium, against photooxidative damage during photosynthesis.},
