Also, catabolic gene cluster absence/presence profiles were shown to be strongly predictive of rhizosphere competence, even more so than a dataset of experimental assays of catabolic potential. 4/4

Running rhizoSMASH on a large collection of plant- and soil-associated genomes enabled charting the first map of root-associated catabolic functions across key plant-associated microbial taxa. 3/4

Similar as for antiSMASH and later gutSMASH, Yuze curated a set of profile HMMs and detection rules to reliably identify these gene clusters, guided by sequence similarity network analysis to distinguish true positives from false positives accurately. 2/4

... and expression (anti-)correlations of biosynthetic gene clusters highlight positive and negative responses to antibiotic production (related to stress response, siderophores, redox balance).

At the same time, for mid-size datasets (most frequent use case), BiG-SCAPE v2 approaches the speed of BiG-SLiCE. For larger datasets, BiG-SCAPE has become more resource-efficient, which now allowed us to analyse >250k BGCs (the antiSMASH database) with it in just a few days on a compute server.

Benchmarking on several different types of ground truth datasets shows the increases in accuracy, with BiG-SLiCE v2 often matching BiG-SCAPE v1 accuracy, and BiG-SCAPE v2 combining its speed increase with a small but notable accuracy gain as well.

BiG-SCAPE was completely rewritten from scratch over the past few years, and now features new alignment modes, a more prominent query mode (which allows you to search genomes from a single BGC query) and more scalable interactive visualizations and data selection/filtering.
