Plasticity of root growth and respiratory activity: Root responses to above-ground senescence, fruit removal or partial root pruning in soybean
(Elsevier Ireland, 2020-01)
This work focuses on the alterations in soybean root growth and activity during whole plant senescence and the contribution of roots to source-sink relations during plant development. The experiments were designed to analyze ...
Root architecture of Arabidopsis is affected by competition with neighbouring plants
(Springer, 2013-01)
Abstract How roots detect and respond to the presence of neighbors is relevant to understand plant belowground interactions. The aim of the present work was to evaluate the effect of the presence of neighboring plants and ...
Physiognomic changes in response to herbivory increase carbon allocation to roots in a temperate grassland of central Argentina
(Springer, 2019-08)
In most temperate grasslands, cattle grazing can promote physiognomic changes on plant communities, as well as changes in species growth patterns. Through these changes in vegetation, cattle grazing can generate changes ...
Lateral root development differs between main and secondary roots and depends on the ecotype
(Taylor & Francis, 2020-04)
Root architecture depends on the development of the main root and also on the number and density of lateral roots. Most molecular knowledge about the development of lateral roots was acquired studying primary roots, and ...
Topsoil Hardening: Effects on Soybean Root Architecture and Water Extraction Patterns
(Springer, 2020-07)
Topsoil hardening is one of the major causes of poor root growth although its effects on subsoil roots are still not well-known. Our aim was to examine the effects of topsoil hardening on the growth and functioning of ...
Root dynamics and survival in a nutrient-poor and species-rich woodland under a drying climate
(Springer, 2018-03-05)
Background and aims: In Australia’s Mediterranean hyperdiverse vegetation, species that produce cluster roots to mobilise poorly-available nutrients (e.g. Banksia spp.) are an important functional and structural component. ...
Different root strategies of perennial native grasses under two contrasting water availability conditions: implications for their spatial distribution in desert dunes
(Springer, 2020-05)
The distribution pattern of perennial native grasses in the dune systems of the Monte desert might be determined by the ability of plant roots to acquire water under drought conditions in different topographical positions ...
Decomposition and nutrient release of grass and tree fine roots along an environmental gradient in southern Patagonia
(Wiley, 2018-10-25)
Decomposition of fine roots is a fundamental ecosystem process that relates to carbon (C) and nutrient cycling in terrestrial ecosystems. However, this important ecosystem process has been hardly studied in Patagonian ...
The significance of roots as hydraulic rheostats
(Oxford University Press, 2010-06)
Roots are the primary sites of water uptake by plants. Roots also sense most of the physico-chemical parameters of the soil, perceive signals from the shoots, and adjust their growth and water transport properties accordingly. ...
AtHB23 participates in the gene regulatory network controlling root branching and reveals differences between secondary and tertiary roots
(Wiley Blackwell Publishing, Inc, 2019-08)
In Arabidopsis, lateral root (LR) development is mainly controlled by several known auxin-regulated transcription factors (TFs). Here, we show that AtHB23 (a homeodomain-leucine zipper I TF) participates in this intricate ...
