Ca2+ signaling in plant manganese uptake: CPK21/23 kinases phosphorylate and activate manganese transporter NRAMP1
نویسندگان
چکیده
Abstract This brief article highlights the results of Fu et al. (Proc Natl Acad Sci USA 119:e2204574119, 2022), who recently found that manganese (Mn) deficiency triggers long-lasting multicellular Ca 2+ oscillations in elongation zone (EZ) Arabidopsis roots and revealed a -CPK21/23-NRAMP1 axis as an important mechanism for plant tolerance adaptation to low Mn.

High-affinity manganese uptake by the metal transporter NRAMP1 is essential for Arabidopsis growth in low manganese conditions.
In contrast with many other essential metals, the mechanisms of Mn acquisition in higher eukaryotes are seldom studied and poorly understood. We show here that Arabidopsis thaliana relies on a high-affinity uptake system to acquire Mn from the soil in conditions of low Mn availability and that this activity is catalyzed by the divalent metal transporter NRAMP1 (for Natural Resistance Associated...
متن کاملIdentification of rice manganese-dependent protein kinases that phosphorylate sucrose synthase at multiple serine residues
Sucrose synthase from the etiolated seedlings of rice (Oryza sativa L. cv. Tainung 67) was phosphorylated both in vivo and in vitro. Four protein kinases that phosphorylated recombinant rice sucrose synthase 1 (RSuS1) in a Mn2+-dependent manner were partially purified and characterized from etiolated rice seedlings. These four kinases, designated as RPK1, RPK2, RPK3 and RPK4, are monomeric enzy...
متن کاملMn-euvering manganese: the role of transporter gene family members in manganese uptake and mobilization in plants
Manganese (Mn), an essential trace element, is important for plant health. In plants, Mn serves as a cofactor in essential processes such as photosynthesis, lipid biosynthesis and oxidative stress. Mn deficient plants exhibit decreased growth and yield and are more susceptible to pathogens and damage at freezing temperatures. Mn deficiency is most prominent on alkaline soils with approximately ...
متن کاملresidual effects of manganese sulfate on growth and on manganese uptake in soybean
a significant portion of manganese (mn) chemical fertilizers applied to calcareous soils is not absorbed by the first crop and may, therefore, affect the growth as well as chemical composition of the subsequent crops, this being called the residual effect of mn, soil tests may be employed to predict such effects. the present experiment was conducted to study the residual effects of manganese su...
متن کاملNramp5 is a major transporter responsible for manganese and cadmium uptake in rice.
Paddy rice (Oryza sativa) is able to accumulate high concentrations of Mn without showing toxicity; however, the molecular mechanisms underlying Mn uptake are unknown. Here, we report that a member of the Nramp (for the Natural Resistance-Associated Macrophage Protein) family, Nramp5, is involved in Mn uptake and subsequently the accumulation of high concentrations of Mn in rice. Nramp5 was con...
