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

Plant Biotechnology Journal, EarlyView.
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 ...

The Genetic Diversity, Population Structure, and Historical Dynamics of Wild Pyrus Species on the Yunnan–Kweichow Plateau

Horticulturae
Located in the southwestern region of China, the Yunnan–Kweichow Plateau, is closely related to the origins of Pyrus L. Despite this important status, there has been relatively little population genetics research focused on the wild Pyrus species in this

Comparative study of pollen morphology and fertility in Pyrus L. species under in situ and ex situ conditions in Greater Caucasus, Azerbaijan [PDF]

BIO Web of Conferences
A number of negative changes are observed in the pollen of the vast majority of plants distributed in polluted areas: morphological immaturity or the observation of sterile pollen grains during pollination, a quantitative decrease in the total ...

Mapping of Fire Blight Resistance QTL in the European Pear (Pyrus communis L.) Cultivar ‘Petersbirne’

Plant Breeding, EarlyView.
ABSTRACT The breeding of pear (Pyrus communis) cultivars that meet market requirements and are at the same time resistant to fire blight is a challenging task beacuse appropriate resistance donors are scarce. To identify valuable resistance sources, phenotypic screening and genetic characterization are indispensable.

Genome‐wide analysis of DNA methyltransferases in a model extremophyte, Schrenkiella parvula: Transcriptional dynamics during development and under salt stress

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Classification of DMTs into 4 subfamilies: two METs, three CMTs, three DRMs, and one DNMT2. The cis‐elements are associated with stress‐response, hormonal regulation, light‐response, and development. RNA‐seq analysis revealed differential expression of DMTs under NaCl stress.

Molecular evolution of Adh and LEAFY and the phylogenetic utility of their introns in Pyrus (Rosaceae)

BMC Evolutionary Biology, 2011
Background The genus Pyrus belongs to the tribe Pyreae (the former subfamily Maloideae) of the family Rosaceae, and includes one of the most important commercial fruit crops, pear. The phylogeny of Pyrus has not been definitively reconstructed.

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.
