Dual ubiquitin signalling by SLOMO controls AUX1 activity and turnover during root gravitropism - The EMBO Journal Gravity-directed growth ensures that shoots and roots grow upwards and downwards, respectively. To achieve this, the organ’s angle with respect to gravity drives the asymmetric redistribution of the plant hormone auxin and consequently differential elongation, thus creating a curvature of the organ. In addition to efflux transporters, the auxin influx transporter AUXIN RESISTANT 1 (AUX1) is essential for auxin redistribution during root gravitropism. Here, we show that the F-box protein SLOMO regulates AUX1 via two distinct mechanisms. First, SLOMO promotes proteolytic degradation of AUX1, possibly in an indirect manner. Second, SLOMO controls the ubiquitination of K261, K264, and K266, thus potentially affecting AUX1 auxin transport properties that are regulated by these residues. This reveals a dual mode of SLOMO-mediated regulation of AUX1, including a novel, non-proteolytic role for SLOMO-mediated ubiquitination in addition to SLOMO-mediated degradation of AUX1.

Using reciprocally retained gene families to detect whole-genome multiplications in plants - Genome Biology Background Traces of ancient whole-genome multiplications (WGMs) have been observed all over the plant kingdom and have been associated with various evolutionary processes, such as increased evolvability, speciation, adaptation to changing environments, domestication and the origin of evolutionary novelties. However, understanding the impact of WGMs on plant evolution requires accurate detection of WGM events, which is challenging because of rapid signal erosion due to genome rearrangements, sequence divergence and the occurrence of additional large- and small-scale duplications. Results Here, we investigate whether reciprocally retained gene families, i.e. gene families that preferentially expand through WGM and rarely exhibit small-scale duplications, can be used as WGM markers in angiosperms. Using stochastic birth-death modeling of gene families’ gene count profiles across species to test for WGM presence or absence, we demonstrate that strongly reciprocally retained gene families have higher power to detect true WGMs and to reject false WGMs than non-reciprocally retained gene families. Conclusions Although none of the reciprocally retained gene families is a perfect WGM marker on its own, we show that using an extended set of such families as input for birth-death and $${K}_{\text {S}}$$ KS distribution modeling approaches leads to better WGM detection performance than using entire genomes. A pipeline to use reciprocally retained gene families for $${K}_{\text {S}}$$ KS distribution-based WGM inference in angiosperms has been implemented in ksrates v2.0.
