Pectate lyase gene regulatory mutants of Erwinia chrysanthemi [PDF]

Journal of Bacteriology, 1986
The pelB gene, which encodes one of the five pectate lyase isoenzymes of Erwinia chrysanthemi 3937, was mutagenized with a mini-Mu transposable element that can form gene fusions to the neomycin phosphotransferase-encoding region. Secondary mutants resistant to kanamycin in the absence of polygalacturonate, an inducer of wild-type pectate lyase ...

A stage‐dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean

Plant, Cell &Environment, Volume 49, Issue 7, Page 3500-3517, July 2026.
Abstract Although seed represents an important means of plant pathogen dispersion, the seed–pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

Xanthomonas euvesicatoria Associated With Outbreaks of Bacterial Blight of Onion in Central Brazil

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
An investigation into bacterial blight (Xanthomonas euvesicatoria) outbreaks in Brazilian onions highlights the critical role of weeds and leftover soybeans as pathogen reservoirs. Effective disease control requires managing these alternative hosts. ABSTRACT Since 2018, outbreaks of typical bacterial blight caused by Xanthomonas have been observed in ...

Chilling Accumulation Shapes Transcriptomic Responses to Warming Exposure During Grapevine Deacclimation

Physiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT During winter, grapevine (Vitis vinifera) bud dormancy and cold hardiness are regulated by complex interactions between chilling accumulation and warm temperature cues. However, the molecular mechanisms underlying physiological transitions during winter remain poorly understood.

Characterization and Functional Analysis of the Poplar Pectate Lyase-Like Gene PtPL1-18 Reveal Its Role in the Development of Vascular Tissues

Frontiers in Plant Science, 2017
Pectin is a major component of plant cell walls, and the structure of pectin impacts on the properties of wood. Although we know that pectate lyase (PL, EC 4.2.2.2) has a major influence on the structure of pectin, our knowledge of Pectate lyase-like ...

Regulation of the Aspergillus nidulans Pectate Lyase Gene (pelA) [PDF]

The Plant Cell, 1989
Aspergillus nidulans pectate lyase was purified from culture filtrates. The enzyme catalyzed a random eliminative cleavage reaction, had an apparent molecular weight of 40,000, and a pl of 4.2. Pectate lyase antisera were produced and used to identify pectate lyase clones in a cDNA expression library.

Full‐Length 16S and 18S rRNA Long‐Read Sequencing Reveals Gut Microbiome Diversity in the European Brown Hare (Lepus europaeus)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Full‐length 16S and 18S rRNA Oxford Nanopore sequencing of large intestine contents from 30 healthy European brown hares revealed broad gut microbiome diversity. An 80% identity threshold detected substantially greater taxonomic richness than 95%, emphasizing the value of long‐read sequencing in wildlife microbiome research. ABSTRACT The European brown

Engineering the bacterial nutrition strategy to control plant diseases

Journal of Integrative Plant Biology, Volume 68, Issue 6, Page 1601-1603, June 2026.
This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.
