Abstract

Drought is one of the major yield-limiting factors under climatic adversaries. The positive role of silicon (Si) in drought tolerance of plants has unfolded a new avenue for enhancing crop productivity through better Si use efficiency. It is hence interesting to understand the mechanistic insights pertaining to its beneficial roles under drought stress conditions. Higher plants sense drought stress via roots which, regulate aboveground plant growth under stress. Cellular and molecular modulations occurring at the root and soil interphases influence the survival and growth of plants under drought stress; therefore, it is intriguing to know how Si influences the soil–root interphase and how this interaction augments overall plant growth under drought. In this review, we summarised the roles of Si in the root systems, rhizosphere and their interactions that could improve plant's growth and development under drought conditions. We have discussed the direct and indirect effects of Si-induced belowground changes on plant roots, soil physical, chemical and biological properties, and their mutual interactions in eliciting defence signalling, including hormone signalling pathways. A mechanistic model of Si-induced beneficial effects in water-limited environments is suggested, which could help improve the management of rainfed croplands through Si fertilisation.

硅介导的耐旱性:根-土壤间期的神秘视角
干旱是气候逆境下限制产量的主要因素之一。硅(Si)在植物耐旱性中的积极作用为通过提高硅的利用效率来提高作物产量开辟了一条新途径。因此,了解硅在干旱胁迫条件下发挥有益作用的机理是很有意义的。高等植物通过根系感知干旱胁迫,并在胁迫下调节地上部植物的生长。根际和土壤际发生的细胞和分子调控影响着植物在干旱胁迫下的存活和生长;因此,了解硅如何影响土壤-根际以及这种相互作用如何促进植物在干旱下的整体生长是很有意义的。在这篇综述中,我们总结了硅在根系、根瘤菌圈中的作用以及它们之间的相互作用,这些作用可以改善植物在干旱条件下的生长和发育。我们讨论了硅诱导的地下变化对植物根系、土壤物理、化学和生物特性的直接和间接影响,以及它们在激发防御信号(包括激素信号途径)方面的相互影响。我们提出了一个在限水环境中硅诱导有益效应的机理模型,该模型有助于通过施硅肥改善雨养耕地的管理。

期刊介绍: The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
