Ultrasmall episymbiotic bacteria grow on the surface of their obligate bacterial hosts. These episymbionts have a restricted host range and likely rely on host-derived receptor molecules to identify and associate with cognate hosts. Nanosynbacteria from the oral microbiome, like Nanosynbacter…
Bone loss and metabolic dysregulation often coexist in older adults, yet the relationship between age-related changes in bone cell metabolism and bone-forming activity remains unclear. By modeling both conditions in aged mice and using in vivo stable-isotope tracing, we demonstrated that…
Sporadically, all plastids produce dynamic tubular extensions in response to myriad stresses. Although the use of fluorescent proteins revealed these transient tubules to be stroma-filled and led to their being called stromules, the mechanism underlying tubule extension from a spheroidal plastid…
Bulk phloem flow is driven by pressure gradients generated by water drawn from the xylem, coupling source-sink transport with water status. Huanglongbing (HLB), a phloem-affecting bacterial disease of citrus, disrupts phloem transport, and causes canopy water deficit. Although improved water…
Understanding how grafts form has fascinated scientists for over a century, and numerous transcription regulators involved in wound healing, callus formation, and grafting have been identified in model plants. However, the genetic architecture underlying grafting traits remains poorly…
Animal pose estimation typically requires manual annotation of body parts to train neural networks for each new recording system or environmental condition. Here we use a general-purpose vision-language model (VLM) to generate annotations in multi-animal recordings of fruit flies (Drosophila…
In a companion study, we introduced ProDive and used it to identify 318,289 high-confidence cross-family segment correspondences across all 25,545 Pfam families. Here we characterize the pervasiveness and biophysical context of the resulting mapped fragment resource. Graph-based community analysis…
Antibiotic resistance is increasingly recognized as a major threat to global health, yet the contribution of non-antibiotics to this problem remains poorly defined. Here, we established a transcriptional chemical genomics approach to map how 2,415 host-relevant small molecules influence…
Synthetic nitrogen fertilizers enhance maize (Zea mays ssp. mays) productivity but impose substantial environmental and economic costs. Some Mexican maize landraces support biological nitrogen fixation (BNF) in aerial root mucilage, raising the question of how much variation exists in this trait…
Intraspecific variation in microbial symbioses is shaped by a variety of ecological and evolutionary processes. In geographically separated populations, divergence in genomic traits is expected due to dispersal barriers and habitat differentiation, whereas sympatric populations might exhibit…
