Rice SPX1 and SPX2 inhibit phosphate starvation responses through interacting with PHR2 in a phosphate-dependent manner.
In plants, sensing the levels of external and internal nutrients is essential for reprogramming the transcriptome and adapting to the fluctuating environment. Phosphate (Pi) is a key plant nutrient, and a large proportion of Pi starvation-responsive genes are under the control of Phosphate Starvation Response Regulator 1 (PHR1) in Arabidopsis (AtPHR1) and its homologs, such as Oryza sativa (Os)...
متن کاملOverexpression of RING Domain E3 Ligase ZmXerico1 Confers Drought Tolerance through Regulation of ABA Homeostasis[OPEN]
Drought stress is one of the main environmental problems encountered by crop growers. Reduction in arable land area and reduced water availability make it paramount to identify and develop strategies to allow crops to be more resilient in waterlimiting environments. The plant hormone abscisic acid (ABA) plays an important role in the plants’ response to drought stress through its control of sto...

متن کاملNegative regulation of phosphate starvation-induced genes.
Phosphate (Pi) deficiency is a major nutritional problem faced by plants in many agro-ecosystems. This deficiency results in altered gene expression leading to physiological and morphological changes in plants. Altered gene expression is presumed to be due to interaction of regulatory sequences (cis-elements) present in the promoters with DNA binding factors (trans-factors). In this study, we a...
متن کاملOsSIZ1, a SUMO E3 Ligase Gene, is Involved in the Regulation of the Responses to Phosphate and Nitrogen in Rice.
SIZ1-mediated SUMOylation regulates hormone signaling as well as abiotic and biotic stress responses in plants. Here, we investigated the expression profile of OsSIZ1 in rice using quantitative reverse transcription-PCR (qRT-PCR) and pOsSIZ1-GUS transgenic plants, and the function of OsSIZ1 in the responses to phosphate and nitrogen using a reverse genetics approach. OsSIZ1 is constitutively ex...
