摘要/Abstract

摘要： 植物基因组大小是指某一物种内一套完整单倍体DNA含量的总和,是生物特征中的一个重要方面,真核生物具有丰富的基因组大小多样性。植物基因组大小与从细胞核到个体水平的一系列功能性状密切相关,在塑造植物功能性状中起着重要作用,并对环境变量具有不同的响应策略。本文综述了植物基因组大小与细胞大小、气孔大小和密度、光合功能性状、细胞周期、种子重量等植物功能性状的关系,及其对温度、降水、海拔、养分、重金属污染等环境变量的响应与适应机制。最后,提出将基因组大小、功能性状和环境适应性相结合,深入探讨全球变化背景下植物对环境变化的响应和适应机制。

关键词: 基因组大小, 功能性状, 环境因子, 环境适应性

Abstract: Plant genome size, the sum of the DNA content of a complete set of haplo groups within a given plant species, is an important aspect of biological characterization. There is abundant genome size diversity in eukaryotes. Plant genome size is closely associated with a range of functional traits from the nucleus to individual level, exerts a vital role in shaping plant functional traits, and helps plants present different response strategies to environmental variables. We viewed the relationship between plant genome size and functional traits, such as cell size, stomatal size and density, photosynthetic functional traits, cell cycle, and seed mass. Their response and adaptation mechanisms to environmental variables, such as temperature, precipitation, altitude, nutrients, and heavy metal pollution, were discussed. Finally, the combination of genome size with functional traits and environmental adaptations was encouraged to deeply explore the response and adaptation mechanisms of plants to environmental changes in the context of global change.

Key words: genome size, functional trait, environmental factor, environmental adaptation
