Strategies for improving phosphorus acquisition efficiency of crop plants. (2010, background): “However, several mutants with aberrant phosphate transporter expression 212 have been well described (Zakhleniuk et al., 2001; Shin et al., 2004; Xu et al., 2007) 213 and suggest the presence of genetic variation among plant genotypes.”
Recent advances in arsenic accumulation and metabolism in rice (2010, background): “Shin et al. (2004) indicated that pht1;1 and pht1;4 mediate a significant proportion of the As(V) uptake in Arabidopsis.”
Arsenic uptake and toxicity in plants: integrating mycorrhizal influences (2010, background): “Work with Arabidopsis mutants has confirmed that Pi transporters also mediate As(V) uptake (Shin et al. 2004).”
Phosphate Acquisition (2004, background): “The in planta evidence for the involvement of high affinity Pi transporters in Pi acquisition under both low and high concentrations of the nutrient came from analysis of Arabidopsis mutants (Shin et al., 2004).”
Signaling network in sensing phosphate availability in plants. (2011, background): “Pi is acquired by Pi transporters encoded by PHT1 genes that are predominantly expressed in epidermal and/or cortical cells (89, 93, 119).”
Feeding hungry plants: The role of purple acid phosphatases in phosphate nutrition (2010, background): “Consistent with this, knockout of Pht1;4 or Pht1;1 results in decreased Pi acquisition during Pi deficiency [36], while knockout of Pht1;1 (PHO1) also results in failure to accumulate Pi in shoots during Pi sufficiency due to its role in xylem Pi loading [37].”
WRKY75 Transcription Factor Is a Modulator of Phosphate Acquisition and Root Development in Arabidopsis1[C][W][OA] (2007, background): “WRKY75 suppression also resulted in the reduced expression of Pht1;1 and Pht1;4, which encode high-affinity Pi transporters (Muchhal et al., 1996; Shin et al., 2004).”
Arsenic Toxicity: The Effects on Plant Metabolism (2012, background): “However, a genotype-dependent proportion of the As is translocated to the shoot and other tissues of the plant.”
Arsenic tolerance in Arabidopsis is mediated by two ABCC-type phytochelatin transporters (2010, background): “Whereas As(V) is taken up by the highaffinity phosphate transporter (31, 32), DSMA is much more hydrophobic and is rapidly absorbed by plant roots.”
Phosphate deficiency signaling pathway is a target of arsenate and phosphate transporter OsPT1 is involved in As accumulation in shoots of rice (2013, background): “In Arabidopsis, disruption of the root Pi transporters, Pho1;1 and Pho1;4, conferred tolerance to As(V) (Shin et al. 2004).”
The roles of membrane transporters in arsenic uptake, translocation and detoxification in plants (2020, background): “In Arabidopsis, mutants of AtPHT1;1 and AtPHT1;4 showed different degrees of increased tolerance to As(V) compared with wild type, suggesting that the phosphate transporters AtPHT1;1 and AtPHT1;4 may have different affinities for As(V) (Shin et al., 2004).”
Arsenic uptake and metabolism in plants. (2009, background): “thaliana double mutant pht1;1Δ4Δ was much more resistant to arsenate than the wild type, indicating that Pht1;1 and Pht1;4 mediate arsenate uptake (Shin et al., 2004).”
