Enantioselective Total Synthesis of (+)-Salvileucalin B [PDF]

, 2011
An enantioselective total synthesis of the diterpenoid natural product (+)-salvileucalin B is reported. Key findings include a copper-catalyzed arene cyclopropanation reaction to provide the unusual norcaradiene core and a reversible retro ...

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Progress toward the Total Synthesis of Saudin: Development of a Tandem Stille-Oxa-Electrocyclization Reaction [PDF]

, 2005
A diastereoselective tandem Stille-oxa-electrocyclization reaction provides access to the core of the diterpenoid natural product saudin. Additionally, this new reaction sequence was extended to the convergent preparation of related polycyclic pyran ...

Mycochemical Diversity and Therapeutic Potential of Hymenochaetoid Fungi from Central Asia: Regional and Global Perspectives

New Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Central Asia harbors a rich yet understudied assemblage of wood‐inhabiting Hymenochaetoid fungi. This review delivers the first comprehensive synthesis of 43 poroid species representing 18 genera documented across montane forests, steppes, and xeric habitats.

Responses of Root Microbiome and Metabolome Are Linked to Crop Disease Severity

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Plant microorganisms are an essential component of the host and perform critical functions in plant development and health. Emerging evidence shows that plants use their root exudates to recruit beneficial microbes that protect them against abiotic and biotic stresses, including diseases.

Temperature Sensitivity of Leaf Wax n‐Alkane Carbon Isotopes: Mechanisms and Implications for Terrestrial Paleoclimates

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract While climate signals encapsulated in the 13C content of C3 plants' leaf wax n‐alkanes are largely tied to precipitation, they may also be sensitive to plant physiological responses to temperature. In this study, statistical analyses on a global data set of modern plants reveal a correlation between the 13C discrimination for leaf waxes ...

Identification of pathogenicity factors in the xylem-invading pathogen Xanthomonas albilineans by Transposon Mutagenesis [PDF]

, 2010
Xanthomonas albilineans is a systemic, xylem-invading pathogen that causes sugarcane leaf scald. Leaf symptoms vary from a single, white, narrow, sharply defined stripe to complete wilting and necrosis of infected leaves, leading to plant death.

Diterpenoid Lactones with Anti-Inflammatory Effects from the Aerial Parts of Andrographis paniculata

Molecules, 2019
Andrographis paniculata (AP) has been widely used in China for centuries to treat various diseases, and especially to treat inflammation. Diterpenoid lactones are the main anti-inflammatory components of AP.
