Plant growth and phosphorus accumulation of wild type and two root hair mutants of Arabidopsis thaliana (Brassicaceae)

Abstract: Arabidopsis thaliana root hairs grow longer and denser in response to low-phosphorus availability. We tested the hypothesis that wild-type Arabidopsis would acquire more phosphorus under phosphorus-limiting conditions than mutants that do not have the root hair response. The growth and phosphorus acquisition of wild-type Arabidopsis (WS) were compared to two root hair mutants (rhd6 and rhd2) under eight phosphorus treatments ranging from 0.4 mmol/m to 54 mmol/m phosphorus. At the lowest phosphorus treatment, a… Show more

“…basic units of the phenotype; Serebrovsky, 1925;Lynch, 2011; for discussion, see York et al, 2013) enhance phosphorus acquisition, including root architectural phenes for topsoil foraging , such as shallow root growth angles Ho et al, 2005), increased basal root whorl number (Lynch and Brown, 2012;Miguel et al, 2013), and adventitious rooting (Miller et al, 2003); phenes to enhance soil exploitation, including root hair length and density (RHL/D; Bates and Lynch, 2000a, 2000bMa et al, 2001a;Gahoonia and Nielsen, 2004;Yan et al, 2004) and phosphorus-solubilizing root exudates (Ryan et al, 2001); mycorrhizal symbioses (Smith and Read, 2008); and phenes that reduce the metabolic cost of soil exploration , such as root etiolation and root cortical aerenchyma (Fan et al, 2003;Lynch, 2010, 2011). It is probable that interactions among these phenes are important in determining the phosphorus acquisition of integrated phenotypes.…”

“…RHL/D are also important for phosphorus acquisition (Bates and Lynch, 2000a, 2000bGahoonia and Nielsen, 2004). Since phosphorus mobility in soil is governed by diffusion rather than mass flow, phosphorus uptake by roots is limited by localized phosphorus depletion in the rhizosphere (Barber, 1995).…”

“…Root hair length and density is reduced in solution culture compared to soil for both maize (Mackay & Barber, 1984) and barley (Gahoonia & Nielsen, 1997;. Root hair length/density is directly correlated with plant uptake of phosphorus (Bates & Lynch, 2000;Gahoonia & Nielsen, 1997) and is also related to zinc uptake efficiency .…”

“…While sapropel composition contains lots of macro and microelements necessary for plants growth, its wide positive effect surpasses synthetic-organic fertilizers. Sapropel mineralisation is slow so its positive effect on soil stays for several years (Kavaliauskienė, 2000;Bates, Lynch, 2000;Fillery, 2007). Also it is known to strongly boost such processes as photosynthesis, which is the main source of plant energy in whole biosphere (Lawlor, 2002).…”
