Abstract

Bud endodormancy in deciduous fruit trees is an adaptive trait evolved by selection for the capacity to survive unfavorable environmental conditions. Deciduous trees require a certain amount of winter chill named chilling requirement (CR) to promote bud endodormancy release. In recent decades, global warming has endangered the chill accumulation in deciduous fruit trees. Developing low-CR cultivars is a practical way to neutralize the effect of climate changes on the cultivation and distribution of deciduous fruit trees. In this review, we focus on the effect of chilling accumulation on bud endodormancy release and the genetic mechanisms underlying the chilling requirement in deciduous fruit trees. Additionally, we put forth a regulatory model for bud endodormancy and provide prospective directions for future research in deciduous fruit trees.

破译落叶果树花芽内蛰释放所需的寒冷遗传机制

落叶果树的花芽内蛰是一种适应性状，是为了在不利的环境条件下生存而经过选择进化而来的。落叶树需要一定量的冬季寒意（称为寒意需求量（CR））来促进花芽分化。近几十年来，全球变暖已危及落叶果树的寒意积累。开发低CR栽培品种是中和气候变化对落叶果树栽培和分布影响的一种实用方法。在这篇综述中，我们重点研究了落叶果树中寒意积累对芽内萌发释放的影响以及寒意需求的遗传机制。此外，我们还提出了芽内蛰的调控模型，并为落叶果树的未来研究提供了前瞻性方向。

期刊介绍： Molecular Breeding is an international journal publishing papers on applications of plant molecular biology, i.e., research most likely leading to practical applications. The practical applications might relate to the Developing as well as the industrialised World and have demonstrable benefits for the seed industry, farmers, processing industry, the environment and the consumer. All papers published should contribute to the understanding and progress of modern plant breeding, encompassing the scientific disciplines of molecular biology, biochemistry, genetics, physiology, pathology, plant breeding, and ecology among others. Molecular Breeding welcomes the following categories of papers: full papers, short communications, papers describing novel methods and review papers. All submission will be subject to peer review ensuring the highest possible scientific quality standards. Molecular Breeding core areas: Molecular Breeding will consider manuscripts describing contemporary methods of molecular genetics and genomic analysis, structural and functional genomics in crops, proteomics and metabolic profiling, abiotic stress and field evaluation of transgenic crops containing particular traits. Manuscripts on marker assisted breeding are also of major interest, in particular novel approaches and new results of marker assisted breeding, QTL cloning, integration of conventional and marker assisted breeding, and QTL studies in crop plants.
