PbrIDD2‐PbrAPX14 Module Functions in the Ethylene‐Mediated Ripening and Senescence Process of Pear Fruit

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4878-4896, August 2026.
ABSTRACT Endogenous H2O2 participated in the ethylene‐dependent ripening and senescence process of horticultural fruit as a secondary messenger; however, the molecular mechanism beneath such a phenomenon has not been fully clarified until recently. By a conjoint analysis of metabolite, enzyme activities, gene expression profiles in AsA‐GSH cycle of ...

3D Chromatin Architecture Provides Insights Into Leaf Trait Variation Among Pear Species

Advanced Science, Volume 13, Issue 41, 22 July 2026.
ABSTRACT Three‐dimensional (3D) chromatin architecture plays a fundamental role in eukaryotic gene regulations, its functional significance in perennial fruit trees remains poorly characterized despite extensive applications in crop genomics. Here, we developed high‐resolution (∼5 kb) Hi‐C maps of Pyrus and compared 3D genomic architecture of three ...

Update on comparative genome mapping between Malus and Pyrus

BMC Research Notes, 2009
Background Comparative genome mapping determines the linkage between homologous genes of related taxa. It has already been used in plants to characterize agronomically important genes in lesser studied species, using information from better studied ...

The Rise of Stemphylium vesicarium: A Growing Threat to Pear Production in Europe

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
Brown spot of pear, caused by the fungus Stemphylium vesicarium, was reported in Italy in 1975 and only recently, due to climate change and pesticide restrictions, it became a major threat for European pear production. New knowledge on this pathogen can allow the advent of new and effective control strategies.

Evolutionary Rate Heterogeneity and Functional Divergence of Orthologous Genes in Pyrus

Biomolecules, 2019
Negatively selected genes (NSGs) and positively selected genes (PSGs) are the two types of most nuclear protein-coding genes in organisms. However, the evolutionary rates and characteristics of different types of genes have been rarely understood. In the

Robust Constrained Partial Least Squares: A Robust Integrated Algorithm for Multivariate Regression in the Presence of Outliers, Interfering Analytes, and Structured External Influences

Journal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT Partial least squares (PLS) regression is widely used for multivariate calibration in high‐dimensional and collinear settings. However, classical PLS relies on least squares optimization and is therefore sensitive to anomalous observations, leverage points, and structured spectral interferences.

Response of Yield, Growth and Iron Deficiency Chlorosis of ‘Santa Maria’ Pear Trees on Four Rootstocks

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2016
This study was conducted on the 'Santa Maria' pear (Pyrus communis L.) budded on various rootstocks [pear seedling (Pyrus communis L.) and quince (Cydonia oblonga Mill.) (BA 29, QA and QC) rootstocks] under calcareous soil and semi-arid conditions during

Beautiful and Useful: Species Richness and the Ecosystem Services of Allotment Gardens in Berlin, Germany

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT Intensive agriculture and urbanization have led to habitat degradation and fragmentation, reducing plant diversity and subsequently reducing pollinator abundance and richness. This paper investigates the conservation potential of green infrastructure in allotment gardens, which are a common form of urban land use.
