FAM161A, associated with autosomal recessive retinitis pigmentosa,localizes at the level of the photoreceptor cilium and interacts with proteins involved in ciliopathies

Purpose: We have previously demonstrated that mutations in the FAM161A gene, encoding a protein with unknown function and no similarities with other characterized sequences, cause autosomal recessive retinitis pigmentosa (RP). The purpose of this work is to investigate the functional role of FAM161A within the retina and its relationship with other proteins involved in RP. Methods: The subcellular localization of FAM161A in the retina was assessed by immunohistochemistry of retinal sections and dissociated photoreceptors from mice, which were stained using antibodies against FAM161A and antibodies against cilium markers. The function of FAM161A was further assessed in ciliated mammalian cell lines by expression of recombinant FAM161A with various fusion tags. The binary interaction between FAM161A and a collection of ciliary and ciliopathy-associated proteins was analyzed using a yeast two-hybrid assay. The results obtained with this technique were validated using independent protein-protein interaction assays (GST-pull downs, co-transfection and co-immunoprecipitation). Results: Native FAM161A localized at the connecting cilium of photoreceptor cells, as demonstrated by immunofluorescence in both dissociated photoreceptors and retinal sections of mice. More specifically, co-staining with markers for ciliary sub-structures (RPGRIP1L, Centrin, RP1, GT335) demonstrated that FAM161A decorated the basal body and the very apical part of the connecting cilium. Upon overexpression in ciliated cultured mammalian cells, FAM161A localized to the ciliary basal body. Yeast two-hybrid analysis of the binary interaction of FAM161A and an array of ciliary proteins revealed the direct interaction of FAM161A with three proteins of which the cognate genes are mutated in retinal ciliopathies. The confirmation of these interactions using different biochemical assays is currently in progress. Conclusions: FAM161A is a ciliary basal body protein of the photoreceptor connecting cilium, rendering the associated RP as a novel retinal ciliopathy. The confined expression of FAM161A in the retina and the direct interaction of FAM161A with other retinal ciliopathy-associated proteins may explain the retinal phenotype of this specific subset of mechanistically and phenotypically connected retinal disorders.

Level of accumulation of epoxy fatty acid in Arabidopsis thaliana expressing a linoleic acid delta12-epoxygenase is influenced by the availability of the substrate linoleic acid.

Arabidopsis thaliana (L.) Heynh. expressing the Crepis palaestina (L.) linoleic acid delta12-epoxygenase in its developing seeds typically accumulates low levels of vernolic acid (12,13-epoxy-octadec-cis-9-enoic acid) in comparison to levels found in seeds of the native C. palaestina. In order to determine some of the factors limiting the accumulation of this unusual fatty acid, we have examined the effects of increasing the availability of linoleic acid (9cis, 12cis-octadecadienoic acid), the substrate of the delta12-epoxygenase, on the quantity of epoxy fatty acids accumulating in transgenic A. thaliana. The addition of linoleic acid to liquid cultures of transgenic plants expressing the delta12-epoxygenase under the control of the cauliflower mosaic virus 35S promoter increased the amount of vernolic acid in vegetative tissues by 2.8-fold. In contrast, the addition to these cultures of linoelaidic acid (9trans, 12trans-octadecadienoic acid), which is not a substrate of the delta12-epoxygenase, resulted in a slight decrease in vernolic acid accumulation. Expression of the delta12-epoxygenase under the control of the napin promoter in the A. thaliana triple mutant fad3/fad7-1/fad9, which is deficient in the synthesis of tri-unsaturated fatty acids and has a 60% higher level of linoleic acid than the wild type, was found to increase the average vernolic acid content of the seeds by 55% compared to the expression of the delta12-epoxygenase in a wild-type background. Together, these results reveal that the availability of linoleic acid is an important factor affecting the synthesis of epoxy fatty acid in transgenic plants.

Verification at the protein level of the PIF4-mediated external coincidence model for the temperature-adaptive photoperiodic control of plant growth in Arabidopsis thaliana.

Plant circadian clock controls a wide variety of physiological and developmental events, which include the short-days (SDs)-specific promotion of the elongation of hypocotyls during de-etiolation and also the elongation of petioles during vegetative growth. In A. thaliana, the PIF4 gene encoding a phytochrome-interacting basic helix-loop-helix (bHLH) transcription factor plays crucial roles in this photoperiodic control of plant growth. According to the proposed external coincidence model, the PIF4 gene is transcribed precociously at the end of night specifically in SDs, under which conditions the protein product is stably accumulated, while PIF4 is expressed exclusively during the daytime in long days (LDs), under which conditions the protein product is degraded by the light-activated phyB and also the residual proteins are inactivated by the DELLA family of proteins. A number of previous reports provided solid evidence to support this coincidence model mainly at the transcriptional level of the PIF 4 and PIF4-traget genes. Nevertheless, the diurnal oscillation profiles of PIF4 proteins, which were postulated to be dependent on photoperiod and ambient temperature, have not yet been demonstrated. Here we present such crucial evidence on PIF4 protein level to further support the external coincidence model underlying the temperature-adaptive photoperiodic control of plant growth in A. thaliana.

Variation in the level of aggression, chemical and genetic distance among three supercolonies of the Argentine ant in Europe.

In their invasive ranges, Argentine ant populations often form one geographically vast supercolony, genetically and chemically uniform within which there is no intraspecific aggression. Here we present regional patterns of intraspecific aggression, cuticular hydrocarbons (CHCs) and population genetics of 18 nesting sites across Corsica and the French mainland. Aggression tests confirm the presence of a third European supercolony, the Corsican supercolony, which exhibits moderate to high levels of aggression, depending on nesting sites, with the Main supercolony, and invariably high levels of aggression with the Catalonian supercolony. The chemical analyses corroborated the behavioural data, with workers of the Corsican supercolony showing moderate differences in CHCs compared to workers of the European Main supercolony and strong differences compared to workers of the Catalonian supercolony. Interestingly, there were also clear genetic differences between workers of the Catalonian supercolony and the two other supercolonies at both nuclear and mitochondrial markers, but only very weak genetic differentiation between nesting sites of the Corsican and Main supercolonies (F(ST) = 0.06). A detailed comparison of the genetic composition of supercolonies also revealed that, if one of the last two supercolonies derived from the other, it is the Main supercolony that derived from the Corsican supercolony rather than the reverse. Overall, these findings highlight the importance of conducting more qualitative and quantitative analyses of the level of aggression between supercolonies, which has to be correlated with genetic and chemical data.
