However, recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and embryogenesis, as well as in protection from pathogens. Scope This review considers the functions of ROS in seed physiology. ROS are present in all cells and at all phases of the seed life cycle. ROS accumulation is important in breaking seed dormancy, and stimulating seed germination and protection from pathogens. However, excessive ROS accumulation can be detrimental. Therefore, knowledge of the mechanisms by which ROS influence seed physiology will provide insights that may not only allow the development of seed quality markers but also help us understand how dormancy can be broken in several recalcitrant species. Conclusions Reactive oxygen species have a dual role in seed physiology. Understanding the relative importance of beneficial and detrimental effects of ROS provides great scope for the improvement and maintenance of seed vigour and quality, factors that may ultimately increase crop yields. date: 2015 date_type: published publication: Annals of Botany volume: 116 publisher: Oxford University Press pagerange: 663-668 refereed: TRUE issn: 0305-7364 official_url: http://dx.doi.org/10.1093/aob/mcv098 related_url_url: https://scholar.google.co.in/scholar?hl=en&q=Seed+birth+to+death%3A+dual+functions+of+reactive+oxygen+species+in+seed+physiology&btnG= related_url_type: pub citation: Jeevan Kumar, S P and Rajendra Prasad, S and Banerjee, R and Thammineni, C (2015) Seed birth to death: dual functions of reactive oxygen species in seed physiology.
