“…Root toughness is determined by structural macro-molecules and crystalline deposits such as lignin, cellulose, callose, silicon and calcium oxalate (Arnott, 1966;1976;Genet et al, 2005;Leroux et al, 2011). Because of the heterogeneous soil environment, roots are amongst the most plastic of plant organs and rapidly allocate structural resources to the roots to allow them to penetrate dense soil and restricted openings (Gregory, 2006).…”

Herbivorous insect pests living in the soil represent a significant challenge to food security given their persistence, the acute damage they cause to plants and the difficulties associated with managing their populations. Ecological research effort into rhizosphere interactions has increased dramatically in the last decade and we are beginning to understand, in particular, the ecology of how plants defend themselves against soil-dwelling pests. In this review, we synthesise information about four key ecological mechanisms occurring in the rhizosphere or surrounding soil that confer plant protection against root herbivores. We focus on root tolerance, root resistance via direct physical and chemical defences, particularly via acquisition of siliconbased plant defences, integration of plant mutualists (microbes and entomopathogenic nematodes, EPNs) and the influence of soil history and feedbacks. Their suitability as management tools, current limitations for their application, and the opportunities for development are evaluated. We identify opportunities for synergy between these aspects of rhizosphere ecology, such as mycorrhizal fungi negatively affecting pests at the root-interface but also increasing plant uptake of silicon, which is also known to reduce herbivory. Finally, we set out research priorities for developing potential novel management strategies. Re: Revision of our review APSOIL-D-16-00199 Dear Prof van Gestel, Many thanks for your email advising us that our paper may be considered for publication pending major revisions. Please find enclosed our revised article New frontiers in belowground ecology for plant protection from root-feeding insects. As you will see this paper has been substantially rewritten and developed. Full details of these changes are in our response to reviewers. We are thankful to both reviewers for constructive comments and suggestions. We are grateful for the extension you provided and very sorry that we were late returning this revision to you. Please don't hesitate to contact me if I can provide further information.

“…In fern roots, mannans are deposited as constituents of cell wall appositions as a defense mechanism to limit microbial ingress (Leroux et al, 2011). Mannans impart hardness to seeds of some plants, such as tomato and lettuce, thereby protecting the embryo and controlling radicle protrusion (Schroder et al, 2009; Buckeridge, 2010).…”

The CELLULOSE SYNTHASE (CESA) superfamily of proteins contains several sub-families of closely related CELLULOSE SYNTHASE-LIKE (CSL) sequences. Among these, the CSLA and CSLC families are closely related to each other and are the most evolutionarily divergent from the CESA family. Significant progress has been made with the functional characterization of CSLA and CSLC genes, which have been shown to encode enzymes with 1,4-β-glycan synthase activities involved in the biosynthesis of mannan and possibly xyloglucan backbones, respectively. This review examines recent work on the CSLA and CSLC families from evolutionary, molecular, and biochemical perspectives. We pose a series of questions, whose answers likely will provide further insight about the specific functions of members of the CSLA and CSLC families and about plant polysaccharide biosynthesis is general.

“…In addition to carbohydrate storage and structure, mannans serve a variety of other functions. In fern roots, mannans are deposited as constituents of cell wall appositions as a defense mechanism to limit microbial ingress [45]. Besides plants, algae are also a viable resource for mannan polysaccharides.…”
