We present an imaging system for pan-neuronal recording in crawling Caenorhabditis elegans. A spinning disk confocal microscope, modified automated tracking of the C. elegans head ganglia, simultaneously records activity and position ∼80 neurons that coexpress cytoplasmic calcium indicator GCaMP6s nuclear localized red fluorescent protein at 10 volumes per second. developed a behavioral analysis algorithm maps movements ganglia to animal's posture locomotion. Image registration software...
Evolution can favor organisms that are more adaptable, provided genetic variation in adaptability exists. Here, we quantify this among 230 offspring of a cross between diverged yeast strains. We measure the each genotype, defined as its average rate adaptation specific environmental condition, and analyze heritability, predictability, basis trait. find initial genotype strongly affects alter future evolution. Initial also pleiotropic consequences for fitness different environment. This...
Abstract From birth to adulthood, an animal’s nervous system changes as its body grows and behaviours mature. The form extent of circuit remodelling across the connectome is unknown. We used serial-section electron microscopy reconstruct full brain eight isogenic C. elegans individuals postnatal stages learn how it with age. overall geometry preserved from adulthood. Upon this constant scaffold, substantial in chemical synaptic connectivity emerge. Comparing connectomes among reveals...
The 'connectome', a comprehensive wiring diagram of synaptic connectivity, is achieved through volume electron microscopy (vEM) analysis an entire nervous system and all associated non-neuronal tissues. White et al. (1986) pioneered the fully manual reconstruction connectome using C. elegans. Recent advances in vEM allow mapping new elegans connectomes with increased throughput, reduced subjectivity. Current studies aim to not only fill remaining gaps original connectome, but also address...
Between December 2012 and May 2017, we conducted a fungal inventory at the Boston Harbor Islands National Recreation Area (BHI) in Massachusetts. We extensively sampled 4 sites (Grape Island, Peddocks Thompson World's End peninsula) occasionally visited others for sampling (Calf Great Brewster Slate Webb Memorial State Park). made over 900 collections, of which 313 have been identified. The survey yielded 172 species 123 genera, 62 families, 24 orders, 11 classes, 2 phyla. report as new, but...
Synaptic refinement is a critical step in nervous system maturation, requiring carefully timed reorganization and of neuronal connections. We have identified myrf-1 myrf-2, two C. elegans homologs Myrf family transcription factors, as key regulators synaptic rewiring. MYRF-1 its paralog MYRF-2 are functionally redundant specifically They co-exist the same protein complex act cooperatively to regulate find that MYRF proteins localize ER membrane they cleaved into active N-terminal fragments,...
This is the sixth contribution in a series devoted to phylogeny and taxonomy of powdery mildews. part includes our third treatment species genus
Abstract A Special-purpose Committee on Fungal Names with the Same Epithet was established at XIX International Botanical Congress (IBC) in Shenzhen, China 2017, a mandate to report 12th Mycological (IMC) recommendations preferred course of action respect names pleomorphic fungi sharing same epithet under Code Nomenclature for algae, fungi, and plants . This provides synthesis deliberations from Committee. We discuss arguments against proposed solution problems that have arisen regarding...
Abstract Since its resurrection, the resinicolous discomycete genus Sarea has been accepted as containing two species, one with black apothecia and pycnidia, orange. We investigate this hypothesis using three ribosomal (nuITS, nuLSU, mtSSU) regions from morphological examination of 70 specimens collected primarily in Europe North America. The results our analyses support separation traditional difformis s.lat. resinae into distinct genera, Zythia . circumscribed is shown to conservatively...

Greenhouse and laboratory experiments were conducted with the potential bioherbicides Colletotrichum graminicola (Cg) Gloeocercospora sorghi (Gs) for control of shattercane weed. Single-spray tank mixture applications containing different ratios two fungi resulted in additive percent weed biomass losses. Intraspecific (Cg + Cg or Gs Gs) interspecific Cg) sequential 1- 7-days apart indicated antagonistic interactions loss. Application either fungus with, 1–3 days prior to, a sub-lethal...
Abstract. Responding to the call for reform in science education, changes were made an introductory meteorology and climate course offered at a large public university. These part of larger project aimed deepening extending program content courses that model effective teaching strategies prospective middle school teachers. Therefore, revisions address misconceptions about meteorological phenomena, foster deeper understanding key concepts, encourage engagement with text, promote inquiry-based...
Growth of strawberry ( Fragaria × ananassa Duch. `Sweetheart') seedlings inoculated with six spore levels ranging from 0 to 12,000 spores/plant the mycorrhizal fungi Glomus intraradices Schenck and Smith was studied in greenhouse plants subsequently moved field. Plant height, leaf area, number leaves increased significantly inoculum densities 750 relation control In greenhouse, there a linear relationship between percent infection density, although cubic field study, were infected indigenous...
The biology of Dicyma pulvinata (Berk. & Curt.) v. Arx, a mycoparasite Cercosporidium personatum Deighton, was investigated under both laboratory and field conditions. At 26 °C, conidia D. close to hyphae C. germinated within 11–17 h. Visible signs colonization lesions by appeared 58–65 h (21–31.5 leaf wetness). an effective protectant when plants were exposed continuous wetness at °C for 5 days. In microplot studies, visibly colonized mutant wild-type isolates 4 days after applying...
