Phytohormone and Light Regulation of Chlorophyll Degradation

Frontiers in Plant Science, 2017
Degreening, due to the net loss of chlorophyll (Chl), is the most prominent symptom during the processes of leaf senescence, fruit ripening, and seed maturation. Over the last decade or so, extensive identifications of Chl catabolic genes (CCGs) have led

PCR amplification of a long rDNA segment with one primer pair in agriculturally important nematodes

Journal of Nematology, 2019
Ribosomal DNA has been a reliable source of taxonomic and phylogenetic markers due to its high copy number in the genome and stable variation with few polymorphisms due to the homogenizing effect of concerted evolution.

Molecular and morphological characterization of Avenae-group cyst nematodes (Heteroderidae) from Greece

Journal of Nematology
Cyst nematodes of the genus Heterodera comprise 87 nominal species of economically important plant parasites, with the Avenae-group one of the largest, consisting of 12 species. Samplings for cyst nematode studies were carried out from multiple locations

New additions to the fungal species of Guyana

Studies in Fungi
DNA barcoding is today a standard method used for species identification, preferably in conjunction with supporting morphological data. Here, we employed DNA barcoding using the highly conserved nuclear ribosomal internal transcribed spacer (ITS) region ...

Enhanced acid fuchsin staining for visualization of foliar nematodes using brightfield and fluorescence microscopy

Journal of Nematology
Foliar nematodes are economically important plant pathogens affecting a wide range of hosts, including food crops, ornamentals, and forest trees. Among these, Litylenchus crenatae (family Anguinidae), the causal agent of beech leaf disease (BLD), poses a

Limited role of aquatic habitat complexity in mitigating the ecological impact of invasive bullfrogs on native amphibians

Global Ecology and Conservation
Spatial overlap in habitat use and structural habitat complexity can shape the ecological impact of biological invasions. Environmental conditions that mitigate these impacts can be exploited in nature-based conservation strategies aimed at damage ...
