Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...

Impact of breeding over the years on Canadian Brassica napus canola

Crop Science, Volume 66, Issue 3, May/June 2026.
Abstract Significant improvements of Canadian Brassica napus canola have been made over the past decades through traditional plant breeding. The objective of this study was to evaluate the oilseed B. napus accessions from a gene bank and canola breeding programs of an industry (private) and the University of Alberta (UofA, public).

Expression and Localization of Nitrilase during Symptom Development of the Clubroot Disease in Arabidopsis [PDF]

Plant Physiology, 2000
Abstract The expression of nitrilase in Arabidopsis during the development of the clubroot disease caused by the obligate biotroph Plasmodiophora brassicae was investigated. A time course study showed that only during the exponential growth phase of the clubs was nitrilase prominently enhanced in infected roots compared with controls ...

Clubroot disease revisited: molecular insights into pathogenesis and host resistance

Phytopathology Research
Plasmodiophora brassicae Woronin, the pathogen responsible for clubroot, poses a major threat to the production of cruciferous crops worldwide. The clubroot disease creates swollen, club-shaped galls on roots, which disrupt water and nutrient transport ...

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

Improved Isolation of Plasmodiophora brassicae Single‐Spores by Laser Microdissection

Plant Pathology, Volume 75, Issue 3, May–June 2026.
This study introduces a novel laser microdissection method for isolating single resting spores of Plasmodiophora brassicae, the pathogen causing clubroot in crucifers. The technique offers a precise, time‐efficient alternative to current protocols, enabling the acquisition of genetically homogeneous isolates for advanced pathogen research.
