TAILIEUCHUNG - Iron and callose homeostatic regulation in rice roots under low phosphorus

Phosphorus (Pi) deficiency induces root morphological remodeling in plants. The primary root length of rice increased under Pi deficiency stress; however, the underlying mechanism is not well understood. | Iron and callose homeostatic regulation in rice roots under low phosphorus .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Ding et al.

The primary root length lt br gt of rice increased under Pi deficiency stress however the underlying mechanism is not well understood. In this lt br gt study transcriptome analysis RNA-seq and Real-time quantitative PCR qRT-PCR techniques were combined lt br gt with the determination of physiological and biochemical indexes to research the regulation mechanisms of iron lt br gt Fe accumulation and callose deposition in rice roots to illuminate the relationship between Fe accumulation lt br gt and primary root growth under Pi deficient conditions. lt br gt Results Induced expression of LPR1 genes was observed under low Pi which also caused Fe accumulation resulting lt br gt in iron plaque formation on the root surface in rice however in contrast to Arabidopsis low Pi promoted primary root lt br gt lengthening in rice. This might be due to Fe accumulation and callose deposition being still appropriately regulated lt br gt under low Pi. The down-regulated expression of Fe-uptake-related key genes including IRT NAS NAAT YSLs lt br gt OsNRAMP1 ZIPs ARF and Rabs inhibited iron uptake pathways I II and III in rice roots under low Pi conditions. In lt br gt contrast due to .
