A cross‐scale approach to unravel the molecular basis of plant phenology in temperate and tropical climates

New Phytologist, Journal Year: 2021, Volume and Issue: 233(6), P. 2340 - 2353

Plants have evolved to time their leafing, flowering and fruiting in appropriate seasons for growth, reproduction resting. As a consequence of adaptation geographically different environments, there is rich diversity plant phenology from temperate tropical climates. Recent progress genetic molecular studies will provide numerous opportunities study the basis phenological traits history seasonal aseasonal environments. Integrating data with long-term climate into predictive models be powerful tool forecast future changes face global environmental change. Here, we review cross-scale approach genes communities three aspects: latitudinal gradient at community level, factors underlying phenology, an integrated based on genetically informed knowledge. Synthesizing latest knowledge about molecular, ecological mathematical perspectives help us understand how natural selection can lead further evolution gene regulatory mechanisms forest ecosystems.

Evolutionary and ecological functional genomics, from lab to the wild

The Plant Journal, Journal Year: 2018, Volume and Issue: 97(1), P. 40 - 55

Published: Nov. 16, 2018

Plant phenotypes are the result of both genetic and environmental forces that act to modulate trait expression. Over last few years, numerous approaches in functional genomics systems biology have led a greater understanding plant phenotypic variation responses environment. These approaches, questions they can address, been loosely termed evolutionary ecological (EEFG), providing key insights on how plants adapt evolve. In particular, by bringing these studies from laboratory field, EEFG allow us gain knowledge function their natural contexts.

Review of the Impact of Apple Fruit Ripening, Texture and Chemical Contents on Genetically Determined Susceptibility to Storage Rots

Plants, Journal Year: 2020, Volume and Issue: 9(7), P. 831 - 831

Published: July 2, 2020

Fungal storage rots like blue mould, grey bull’s eye rot, bitter rot and brown destroy large amounts of the harvested apple crop around world. Application fungicides is nowadays severely restricted in many countries production systems, these problems are therefore likely to increase. Considerable variation among cultivars resistance/susceptibility has been reported, suggesting that efficient defence mechanisms can be selected for used plant breeding. These are, however, vary between pathogens, since some fungi mainly wound-mediated while others attack through lenticels or by infecting blossoms. Since mature fruits considerably more susceptible than immature fruits, involving fruit-ripening processes play an important role. Significant associations have detected susceptibility fruit various maturation-related traits ripening time, firmness at harvest rate softening during storage, as well biochemical contents acidity, sugars polyphenols. Some sources resistance mould described, but research needed on development spore inoculation methods produce reproducible data screenings, especially lenticel-infecting fungi.

A Pollen‐Based Assisted Migration for Rapid Forest Adaptation

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

Published: Jan. 1, 2025

ABSTRACT Climate change poses an unprecedented threat to forest ecosystems, necessitating innovative adaptation strategies. Traditional assisted migration approaches, while promising, face challenges related environmental constraints, forestry practices, phytosanitary risks, economic barriers, and legal constraints. This has sparked debate within the scientific community, with some advocating for broader implementation of despite these limitations, others emphasize importance local adaptation, which may not keep pace rapid rate climate change. opinion paper proposes a novel pollen‐based strategy as potential middle ground in this debate. By leveraging existing seed orchard infrastructure controlled pollen transfer, approach aims enhance resilience through introduction genetic material from climatically suitable sources acknowledging adaptation. We assess implications proposed computer simulation. Additionally, we examine ecological gene flow, discussing benefits heterosis risks outbreeding depression intra‐specific hybrid populations. further explore advantages mitigating reducing simplifying considerations compared traditional or seedling transfer methods. Regional perspectives on adapting are provided, specific examples Northern Central Europe. highlight how could be integrated into practices regulatory frameworks European Union. conclude by inclusion future international projects operational forestry, emphasizing need adaptable policies that can support management strategies

Spring Is Coming: Genetic Analyses of the Bud Break Date Locus Reveal Candidate Genes From the Cold Perception Pathway to Dormancy Release in Apple (Malus × domestica Borkh.)

Frontiers in Plant Science, Journal Year: 2019, Volume and Issue: 10

Published: March 7, 2019

Chilling requirement for bud dormancy completion determines the time of break in apple (Malus × domestica Borkh.). The molecular control is highly heritable, suggesting a strong genetic trait. An available Infinium II SNP platform genotyping containing 8,788 single nucleotide polymorphic markers was employed, and linkage maps were constructed F1 cross from low chilling cv. M13/91 moderate Fred Hough. These used to identify quantitative trait loci (QTL) date as related release. A major QTL detected at beginning group (LG) 9. This remained stable during seven seasons two different growing sites. To increase mapping efficiency detecting contributing genes underlying this QTL, 182 additional located locus used. Combining structural characterization region, high proportion phenotypic variance explained by coincident positioning Arabidopsis orthologues ICE1, FLC PRE1 protein-coding genes. proximity these most explanatory suggests potential additive effects, reinforcing hypothesis inter-dependent mechanisms controlling induction release trees.
