Venturia inaequalis Can Initiate Sexual Reproduction Prior to Leaf‐Fall: New Electron Microscopy Evidence

open access: yesPlant Pathology, EarlyView.
SEM images show Venturia inaequalis pseudothecia (sexual mating structures) can begin to develop prior to leaf‐fall, but subsequently mature on the ground. ABSTRACT Apple scab, caused by Venturia inaequalis, is a major disease of cultivated apples (Malus × domestica) worldwide.

Differences in apple fruit shape are independent of fruit size

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Fruit quality is crucial in breeding new apple varieties. Before tasting, consumers assess freshness and flavor based on the physical appearance of fruit. Understanding how fruit quality traits such as shape and size vary across diverse apples [Malus domestica (Suckow) Borkh.] provides a foundation for future breeding efforts.

Overexpression of a Novel Apple NAC Transcription Factor Gene, MdNAC1, Confers the Dwarf Phenotype in Transgenic Apple (Malus domestica)

open access: yesGenes, 2018
Plant height is an important trait for fruit trees. The dwarf characteristic is commonly associated with highly efficient fruit production, a major objective when breeding for apple (Malus domestica).

Oviposition Response to Light With Different Spectra in the Crepuscular Moth Grapholita molesta

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
The crepuscular moth Grapholita molesta can discriminate differences in light wavelength, exhibiting a strong preference to lay eggs in UV light. ABSTRACT The light spectrum is a critical visual feature influencing insect behavior. The crepuscular moth Grapholita molesta (Busck), a significant pest of stone and pome fruits worldwide, has been shown to ...

Tissue location of resistance in apple to the rosy apple aphid established by electrical penetration graphs [PDF]

open access: yes, 2009
A study of the constitutive resistance of the apple cultivar Florina, Malus domestica Borkh. (Rosaceae), to the rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera Aphididae), was performed for the first time by the electrical penetration graph

Population-level gene copy number variations reveal distinct genetic properties of different Malus species

open access: yesBMC Genomics
Background Copy number variations (CNVs) are crucial in plant evolution, adaptation, and domestication. In this study, we explored how CNVs contribute to genetic diversity, evolution, and adaptation during apple domestication. We examined the genome-wide

Anything you can eat, I can eat better: Evidence of generalism from species to individual level in an insect herbivore

open access: yesEcology, Volume 106, Issue 9, September 2025.
Abstract Most insect herbivores specialize on a few host plants; however, there are a minority of highly generalized species capable of feeding on hundreds of hosts. Generalism could emerge as a property of the species as a whole, while individuals would still exhibit greater specialization at more specific organizational levels.
