Primitive Genepools of Asian Pears and Their Complex Hybrid Origins Inferred from Fluorescent Sequence-Specific Amplification Polymorphism (SSAP) Markers Based on LTR Retrotransposons. [PDF]

PLoS ONE, 2016
Recent evidence indicated that interspecific hybridization was the major mode of evolution in Pyrus. The genetic relationships and origins of the Asian pear are still unclear because of frequent hybrid events, fast radial evolution, and lack of ...

Determination of Potential Pollinizer Grafted Pear Hybrids (Pyrus communis × Pyrus pyrifolia) for Subtropical Regions in Brazil

Journal of Agricultural Science, 2019
The pear tree is originally a temperate-climate fruit tree. The cross Pyrus communis × Pyrus pyrifolia generated hybrid cultivars adapted to subtropical regions. However, the low effective fruiting is a limiting factor for the expansion of pear tree crops in subtropical regions and no pollinizer plants have been identified for these cultivars

Ice Nucleation and Freezing Consequences in Perennial Plants

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT The precise location where ice forms in plants affects the physical constraint it exerts on the different biological compartments (cells, tissues, organs). It is therefore critical to understand where and how ice nucleates to predict the extent of low temperature damage.

S-RNase disrupts tip-localized reactive oxygen species and induces nuclear DNA degradation in incompatible pollen tubes of Pyrus pyrifolia

, 2010
Pear (Pyrus pyrifolia L.) has an S-RNase-based gametophytic self-incompatibility (SI) mechanism, and S-RNase has also been implicated in the rejection of self-pollen and genetically identical pollen.

Multifaceted roles of BBX transcription factors: impacts on key agronomical traits and environmental resilience

New Phytologist, Volume 250, Issue 2, Page 762-787, April 2026.
Summary B‐box (BBX) proteins were initially characterized as transcription factors connecting light signaling to the regulation of flowering time and seedling photomorphogenesis. However, over the last decade, increasing evidence has shown that they integrate light and hormone signaling, modulating multiple physiological processes during plant life. In

A Systematic Approach to Field Testing of Biological Products for Horticulture Is Required to Improve Food Security

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Food security challenges require immediate action to increase food production. Many biological products derived from plant, animal or microbial sources claim they sustainably increase yield, but there are concerns about biosecurity to be investigated before their introduction to the field.

The mirage of DNA methylation in transcriptional regulation of plants

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract “Cytosine methylation plays an important role in the regulation of gene expression in plants.” Some iteration of this statement can be found in most papers centered on plant epigenetics and has become a widely accepted textbook claim. However, our generalized understanding of how DNA methylation exerts control over transcription is now ...

Flowering synchrony and cultivar compatibility as key factors for optimising sweet cherry pollination and production

Annals of Applied Biology, Volume 188, Issue 1, Page 229-245, January 2026.
Effective pollination is crucial for sweet cherry production, as 82% of its yield depends on animal pollination. However, factors like flower phenology and cultivar compatibility are often overlooked in orchard management. Our study shows that flower phenology is a key aspect to determine suitable cultivars, and that pollen tube growth is a practical ...
