Loss of Pathogenicity and Evidence of Horizontal Gene Transfer in Colletotrichum gloeosporioides From a Medicinal Plant. [PDF]

Mol Plant Pathol
A Colletotrichum gloeosporioides strain from Huperzia serrata lacks key pathogenicity genes CgDN3 and cap20 and has fewer pelB, pnl and pg genes. pksIII, for synthesis of huperzine A, was probably acquired by the host plant from the fungus. ABSTRACT Colletotrichum gloeosporioides is a major agricultural pathogen of crops that has also been identified ...

Drastic mycorrhizal community shifts in Sceptridium ferns during the generation transition from fully mycoheterotrophic gametophytes to photosynthetic sporophytes. [PDF]

New Phytol
Summary Many plant species experience a prolonged subterranean phase during which they rely entirely on mycorrhizal fungi for carbon. While this mycoheterotrophic strategy spans liverworts, lycophytes, and ferns, most empirical research has centered on angiosperms.

Pest categorisation of Pestalotiopsis microspora

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract Following an EFSA commodity risk assessment of bonsai plants (Pinus parviflora grafted on Pinus thunbergii) imported from China, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis microspora, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae.

Non‐seed plants are emerging gene sources for agriculture and insect control proteins

The Plant Journal, Volume 116, Issue 1, Page 23-37, October 2023., 2023
SUMMARY The non‐seed plants (e.g., charophyte algae, bryophytes, and ferns) have multiple human uses, but their contributions to agriculture and research have lagged behind seed plants. While sharing broadly conserved biology with seed plants and the major crops, non‐seed plants sometimes possess alternative molecular and physiological adaptations ...

Potent effects of alkaloid-rich extract from Huperzia selago against sodium nitroprusside-evoked PC12 cells damage via attenuation of oxidative stress and apoptosis

Folia Neuropathologica, 2016
Imbalance between production and scavenging of free radicals and other reactive oxygen species (ROS) is a component of many diseases, but it is especially important in aging-related diseases of the central nervous system.

Using photogrammetry to create virtual permanent plots in rare and threatened plant communities

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise Many plant communities across the world are undergoing changes due to climate change, human disturbance, and other threats. These community‐level changes are often tracked with the use of permanent vegetative plots, but this approach is not always feasible.

The cell walls of different Chara species are characterized by branched galactans rich in 3‐O‐methylgalactose and absence of AGPs

Physiologia Plantarum, Volume 175, Issue 4, July/August 2023., 2023
Abstract Streptophyte algae are the closest relatives to land plants; their latest common ancestor performed the most drastic adaptation in plant evolution around 500 million years ago: the conquest of land. Besides other adaptations, this step required changes in cell wall composition.
