Identification of aluminum-responsive microRNAs in Medicago truncatula by genome-wide high-throughput sequencing
Aluminum toxicity High-throughput sequencing Medicago MicroRNA
2015/2/5
MicroRNAs (miRNAs) play important roles in response of plants to biotic and abiotic stresses. Aluminum (Al) toxicity is a major factor limiting plant growth in acidic soils. However, there has been li...
Citrate exudation from white lupin induced by phosphorus deficiency differs from that induced by aluminum
aluminum citrate exudation cluster root phosphorus deficiency white lupin (Lupinus albus)
2015/2/5
Both phosphorus (P) deficiency and aluminum (Al) toxicity induce root exudation of carboxylates, but the relationship between these two effects is not fully understood.Here, carboxylate exudation indu...
Aluminum-Induced Ethylene Production is Associated with Inhibition of Root Elongation in Lotus japonicus L.
Aluminum toxicity Ethylene production Lotus japonicus Medicago truncatula Root elongation
2015/2/5
Inhibition of root elongation by toxic aluminum (Al3+) occurs rapidly and is one of the most distinct and earliest symptoms of Al toxicity. To elucidate mechanism underlying Al3+-induced inhibition of...
Inhibition of nitric oxide synthase (NOS) underlies aluminum-induced inhibition of root elongation in Hibiscus moscheutos
aluminum (Al) toxicityHibiscus moscheutosnitric oxide (NO)nitric oxide synthase (NOS)root elongation
2015/2/5
Aluminum (Al) is toxic to plants when solubilized into Al3+ in acidic soils, and becomes a major factor limiting plant growth. However, the primary cause for Al toxicity remains unknown.Nitric oxide (...
Fluxes of dissolved aluminum and manganese to the Weddell Sea and indications for manganese co-limitation
Fluxes dissolved aluminum manganese to the Weddell Sea indications manganese co-limitation
2014/4/2
The trace metals aluminum (Al) and manganese (Mn) were studied in the Weddell Sea in March 2008.Concentrations of dissolved Al ([Al]) were slightly elevated (0.23–0.35 nmol L21) in the surface layer c...
