Abstract Arbuscular mycorrhizal (AM) fungi are capable of exploiting organic nitrogen sources, but the molecular mechanisms that control such an uptake still unknown. Polymerase chain reaction-based approaches, bioinformatic tools, and a heterologous expression system have been used to characterize sequence coding for amino acid permease (GmosAAP1) from AM fungus Glomus mosseae. The GmosAAP1 shows primary secondary structures similar those other fungal permeases. Functional complementation...
Amino acids are the currency of nitrogen exchange between source and sink tissues in plants constitute a major components used for cellular growth differentiation. The characterization new amino acid transporter belonging to permease (AAP) family, AAP11, expressed perennial species Populus trichocarpa is reported here. PtAAP11 expression analysis was performed by semi-quantitative RT-PCR GUS activity after poplar transformation. function studied detail heterologous yeast. genome contains 14...
Abstract: Regulation of uptake and compartmentation metal ions is important for the maintenance ion homeostasis. To identify mechanisms involved in protection plants from Mn toxicity, wild‐type yeast was transformed with an Arabidopsis cDNA library transformants were screened on toxic concentrations. Wild‐type could not grow presence 30 mM MnSO 4 , while two carrying variants same gene able to grow. Database searches revealed that isolated cDNAs correspond AtCAX2, previously described as a...
The intimate Arbuscular mycorrhiza (AM) association between roots and obligate symbiotic Glomeromycota ('AM fungi') 'feeds' about 80% of land plants. AM forming fungi supply plants with inorganic nutrients have an enormous impact on terrestrial ecosystems. In return, obtain up to 20% the plant-fixed CO2, putatively as monosaccharides. a recent work we reported characterization first glomeromycotan monosaccharide transporter, GpMST1, its gene sequence. We discuss that might take sugars...
Plants have evolved signaling mechanisms such as the multi-step phosphorelay (MSP) to respond different internal and external stimuli. MSP responses often result in gene transcription regulation that is modulated through factors B-type Arabidopsis response regulator (ARR) proteins. Among these proteins, ARR2 a key component expressed ubiquitously involved many aspects of plant development. Although it has been noted ARRs bind their cognate genes DNA-binding domain termed GARP domain, little...
