The Arabidopsis Purple Acid Phosphatase AtPAP10 Is Predominantly Associated with the Root Surface and Plays an Important Role in Plant Tolerance to Phosphate Limitation1[W][OA]
Functional analyses of multiple atpap10 mutant alleles and overexpressing lines indicated that AtPAP10 plays an important role in plant tolerance to Pi limitation, and genetic manipulation of AtP AP10 expression may provide an effective means for engineering new crops with increased tolerance toPi deprivation.

Ethylene signalling is involved in regulation of phosphate starvation-induced gene expression and production of acid phosphatases and anthocyanin in Arabidopsis.
It is found that ethylene signalling plays a negative role in Pi starvation-induced anthocyanin production and will help to gain a better understanding of the molecular mechanism underlying these responses. Expand
Functional disruption of the pentatricopeptide protein SLG1 affects mitochondrial RNA editing, plant development, and responses to abiotic stresses in Arabidopsis.
The functional characterization of the slg1 mutant revealed a putative link between mitochondrial RNA editing and plant responses to abiotic stress and revealed an increased expression of genes involved in the alternative respiratory pathway, which may compensate for the disrupted function of complex I.

The results suggest that mandarin fish has the JAK/STAT signal transduction pathways similar to those in mammals, and these signalling pathways may play an important role in regulation of antiviral responses in fish. Expand
R-Spondin Potentiates Wnt/β-Catenin Signaling through Orphan Receptors LGR4 and LGR5
It is demonstrated that RSPO binds to the extracellular domain of L GR4 and LGR5, and that overexpression of LGR4 strongly sensitizes cells to RSPo-activated β-catenin signaling, which will facilitate the further characterization of these receptor/ligand pairs in regenerative medicine applications.

Interestingly, Pi levels are essentially the same for the WT and overexpressing lines, although these two types of plants have significantly different growth phenotypes, suggesting that the APases may have other roles besides enhancing internal Pi recycling or releasing Pi from external organophosphates for plant uptake. Expand
cpSecA, a thylakoid protein translocase subunit, is essential for photosynthetic development in Arabidopsis.
It is inferred that AtcpSecA plays an essential role in chloroplast biogenesis, the absence of which triggered a retrograde signal, eventually leading to a reprogramming of chlorop last and mitochondrial gene expression. Expand
Genetic and Genomic Evidence That Sucrose Is a Global Regulator of Plant Responses to Phosphate Starvation in Arabidopsis1[W][OA]
The isolation of an Arabidopsis mutant, hypersensitive to phosphate starvation1 (hps1), which has enhanced sensitivity in almost all aspects of plant responses to Pi starvation, provides compelling evidence that sucrose (Suc) is a global regulator of plant response toPi starvation. Expand
Signaling components involved in plant responses to phosphate starvation.
An overview of some major responses of plants to Pi starvation is provided, then what is known so far about the signaling components involved in these responses, as well as the roles of sugar and phytohormones are summarized. Expand

It is proposed that under normal growth conditions, the level of ethylene is low in root cells; a group of key transcription factors trigger the transcription of their target genes to promote root hair development; Pi starvation increases the levels of the protein EIN3, which directly binds to the promoters of the genes targeted by RSL4 and its homologs and further increase their transcription, resulting in the enhanced production of root hairs.
