The rhizosphere is a dynamic region governed by complex interactions between plants and the organisms that are in close association with the root. The composition and pattern of root exudates affect microbial activity and population numbers, which in turn have an impact on the nematodes and microarthropods ... The Plant Root System and Its Functions cropsreview.com the plant root system distinguished from the shoot, its functions. The plant root system constitutes the major part of the plant body, both in terms of function and bulk. In terrestrial plants, the root system is the subterranean or underground part of the plant body while the shoot is the aboveground part. Roots are branching organs which grow downward into the soil, a manifestation of ... THE ROLE OF ROOT EXUDATES IN ... researchgate.net ANRV274 PP57 10 ARI 5 April 2006 196 The Role of Root Exudates in Rhizosphere Interactions with Plants and Other Organisms Harsh P. Bais,5 Tiffany L. Weir,1,2 Laura G. Perry,2,3 Simon Gilroy,4 ... Role of cytokinin in the regulation of root gravitropism ... The models explaining root gravitropism propose that the growth response of plants to gravity is regulated by asymmetric distribution of auxin (indole 3 acetic acid, IAA). Since cytokinin has a negative regulatory role in root growth, we suspected that it might function as an inhibitor of tropic root elongation during gravity response. ROOT SYSTEM National Institute of Open Schooling BIOLOGY MODULE 2 Root System Forms and Function of Plants and Animals 134 Notes 6.2. TYPES OF ROOT SYSTEMS Root systems are mainly of two types (i) Tap root system — It is the root system that develops from the radicle and continues as the primary root (tap root) which gives off lateral roots. Plant Growth Auxins and Gibberellins | Biology for All | FuseSchool Having been made in the tips of the stems and roots, auxin is moved in solution by diffusion to older parts of the plant. In the stem, the auxin causes the cells to change in elasticity. The Plant Detective bbsrc.ukri.org • Describe the effect of light, air and water on plant growth • Explain the role of the leaf in producing new material for growth • Explain that the root anchors the plant, and that water and nutrients are taken in through the root and transported through the stem to other parts of the plant Mycorrhiza Meaning, Types and Role Biology Discussion Features of Mycorrhiza 3. Types 4. Role in Agriculture and Forestry. Meaning of Mycorrhiza Vitadini (1842) was the first to recognise the possible beneficial role of fungal mycelia which mantle the root of higher plants, and this associ­ation is named as mycorrhiza (pl. mycorrhizae) i.e., the fungal root, by Frank (1885).
