Quantifying pollen and spore morphology using a language model

In a typical systematic paper, specimen morphology is described with natural language, and taxonomic specialists use glossaries of technical terminology to establish and communicate taxon concepts, using morphology to delimit species. Textual descriptions of specimen morphology a...

Disentangling the species diversity of Inocybe sect. Petiginosae (Inocybaceae) in Europe and North America

Abstract A multigene phylogenetic assessment of European and North American species in Inocybe sect. Petiginosae based on ITS, LSU and RPB2 rDNA sequence data was undertaken to enable a systematic revision. Specimens collected in northern boreal to arctic-alpine ecosystems were s...

Corylus avellana Disease Management: Using Metagenomics to Illuminate the Rhizosphere Microbiome of Hazelnut

The European hazelnut, Corylus avellana, is an economically important tree nut crop. The biotrophic ascomycete pathogen Anisogramma anomala, found naturally associated with wild C. americana, continues to pose a significant threat to European hazelnut production across North Amer...

Exploring L-tyrosine and L-DOPA biosynthesis in faba bean ( Vicia faba L.)

BACKGROUND AND AIMS: L-DOPA is an important pharmaceutical that accumulates to high levels in the legume faba bean (Vicia faba). L-DOPA is likely derived from L-tyrosine but the responsible enzyme (L-tyrosine oxidase) remains unknown. Availability of L-tyrosine may be a key facto...

The rice cellulose synthase-like D4 gene ( OsCSLD4 ) is required for resistance to Xanthomonas pv. oryzae

Plant cell walls serve as a physical support and a barrier to pathogen invasion. Cellulose is the main component of cell walls. The cellulose synthase-like D ( CSLD ) subfamily genes are required for plant normal development. In rice, Oscsld4 mutant plants are dwarfed and have na...

Trade-Offs Associated with Virulence of Soybean Cyst Nematode on the Broad-Spectrum Resistance Source PI 437654

) poses a major challenge to soybean production, intensified by the declining effectiveness of natural resistance against this pathogen. Although the use of resistant soybean varieties can be effective, their widespread and repeated use ultimately results in the emergence of viru...

Genetic architecture and evolution of stripe rust resistance uncovered using diverse panels of wheat lines and North American Puccinia striiformis f. sp. tritici isolates

Abstract Key message Screening global wheat germplasm with a diverse collection of pathogen races expands the catalog of novel Yr loci and identifies new sources of broad-spectrum resistance against evolving Pst populations. Abstract Newly emerging highly virulent races of Puccin...

Ribosome stalling position, spacing, and A-site occupancy impact translation and cotranslational mRNA decay in plants

Abstract Rate limitation in translational elongation causes ribosomes to pause as they decode an open reading frame (ORF). The triggers and outcomes of these events are poorly understood in plants. Here, we size, map, and quantify footprints of individual (monosome) and closely s...

Less cooperative belowground plant mutualists negatively affect aboveground herbivore growth and survival

Abstract Resource mutualists like nitrogen (N)-fixing rhizobia can improve the nutrition of plants available to higher trophic levels. However, there is substantial intraspecific variation in mutualist quality. How this variation in mutualist quality affects higher trophic levels...

Temperature and soil microbial community interact to alter performance across populations of a native plant

Abstract Abiotic and biotic factors interact to shape the expression of traits and fitness. In contemporary environments, species must respond not only to novel climates but also to altered biotic interactions, and these pressures likely differ across the landscape, which affects...

The combination of morphogenic regulators BABY BOOM and GRF ‐ GIF improves maize transformation efficiency and promotes leaf regeneration

Summary Transformation is an indispensable tool for plant genetics and functional genomics. Although stable transformation in maize is no longer a major obstacle, there remains a need for accessible and efficient methods for academic laboratories. Here, we present the GGB system,...

Complete genome sequences of eight potential biocontrol microorganisms isolated from Washington apple orchards

ABSTRACT Eight potential biocontrol bacteria were isolated from diseased apple ( Malus domestica ) tissues. Here, we report high-quality complete genome sequences for the eight isolates. These data might help in understanding the genetic basis of biocontrol activity, strain compa...
