Abstract
The performance of crop plants is critically affected by biotic and abiotic stress. These stressors threaten food availability by reducing overall crop yield and productivity. Changes in chromatin state by epigenetic modification are part of plant adaptive and survival responses and are considered pivotal for improving agronomic traits. Epigenetics is an exciting field that involves heritable gene expression changes that do not require changes in DNA sequence. Epigenetic modification is well known as a crucial player in plant phenotypic diversity and defense against pathogens. Hence, there is a growing interest in unlocking the epigenome for crop improvement. Herein, we highlight the epigenetic modifications implicated in plant biotic stress response and their contributions to important agronomic traits. We also discussed adopting epigenetics to expand phenotypic diversity and produce desired characteristics in crop plants.
作物的表现受到生物和非生物胁迫的严重影响。这些胁迫因素会降低作物的总产量和生产力，从而威胁粮食供应。通过表观遗传修饰改变染色质状态是植物适应和生存反应的一部分，被认为是改善农艺性状的关键。表观遗传学是一个令人兴奋的领域，它涉及无需改变 DNA 序列的遗传基因表达变化。众所周知，表观遗传修饰是植物表型多样性和抵御病原体的关键因素。因此，人们对解开表观基因组以改良作物的兴趣与日俱增。在这里，我们重点介绍了与植物生物胁迫响应有关的表观遗传修饰及其对重要农艺性状的贡献。我们还讨论了采用表观遗传学来扩大表型多样性并产生作物植物所需的特性。
期刊介绍：
Plant Biotechnology Reports publishes original, peer-reviewed articles dealing with all aspects of fundamental and applied research in the field of plant biotechnology, which includes molecular biology, genetics, biochemistry, cell and tissue culture, production of secondary metabolites, metabolic engineering, genomics, proteomics, and metabolomics. Plant Biotechnology Reports emphasizes studies on plants indigenous to the Asia-Pacific region and studies related to commercialization of plant biotechnology. Plant Biotechnology Reports does not exclude studies on lower plants including algae and cyanobacteria if studies are carried out within the aspects described above.
