How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Ga and Gß Proteins Regulate the Cyclic AMP Pathway That Is Required for Development and Pathogenicity of the Phytopathogen Mycosphaerella graminicola [PDF]

We identified and functionally characterized genes encoding three G alpha proteins and one G beta protein in the dimorphic fungal wheat pathogen Mycosphaerella graminicola, which we designated MgGpa1, MgGpa2, MgGpa3, and MgGpb1, respectively.

Conidial Morphogenesis and Septin-Mediated Plant Infection Require Smo1, a Ras GTPase-Activating Protein in Magnaporthe oryzae [PDF]

, 2018
The pathogenic life cycle of the rice blast fungus Magnaporthe oryzae involves a series of morphogenetic changes, essential for its ability to cause disease. The smo mutation was identified > 25 years ago, and affects the shape and development of diverse

Host‐Induced Silencing of Rhizoctonia Solani 5‐Enolpyruvylshikimate‐3‐Phosphate Synthase Impairs Its Virulence in Rice

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3573-3593, June 2026.
ABSTRACT Sheath blight disease of rice caused by the fungal pathogen R. solani AG1‐IA remains a big threat to rice production worldwide. A limited genetic variation in rice for tolerance to this pathogen and little success in understanding how it defeats host defence are major reasons behind it.

The Melanin Biosynthesis Genes of Alternaria alternata Can Restore Pathogenicity of the Melanin-Deficient Mutants of Magnaporthe grisea

Molecular Plant-Microbe Interactions, 1997
The phytopathogenic fungi Magnaporthe grisea and Alternaria alternata produce melanin via the polyketide biosynthesis, and both fungi form melanized colonies. However, the site of melanin deposition and the role of melanin in pathogenicity differ between

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad‐Spectrum Antiviral Resistance in Crops

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3821-3839, June 2026.
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...

Definition of Tissue-Specific and General Requirements for Plant Infection in a Phytopathogenic Fungus

Molecular Plant-Microbe Interactions, 2001
Although plant diseases are usually characterized by the part of the plant that is affected (e.g., leaf spots, root rots, wilts), surprisingly little is known about the factors that condition the ability of pathogens to colonize different plant tissues ...

The Transcription Factor OsWRKY64 Interacts With OsART1 to Positively Regulate Al Resistance in Rice

Plant Biotechnology Journal, EarlyView.
A proposed working model illustrating the cooperative regulation of Al tolerance by OsWRKY64 and OsART1 in rice. Under Al stress conditions in acidic soil, the transcription factor OsART1 directly binds to the promoter of OsWRKY64 to activate its transcription. The synthesized OsWRKY64 protein then physically interacts with OsART1 in the nucleus.

Disease resistance of transgenic rice by overexpressing OsiWRKY gene

浙江大学学报. 农业与生命科学版, 2005
To derermine its bioiogical function, we transformed OsiWRKY gene into rice. Southern blot and Northern blot analyses showed that the OsiWRKY gene had been integrated into rice genome and overexpressed in rice.
