Phosphorus (P) nutrition is always a key issue regarding plants responses to elevated CO2. Yet it is unclear of how elevated CO2 affects P uptake under different nitrogen (N) forms. This study investigated the influence of elevated CO2 (800 µl l–1) on P uptake and utilization by Arabidopsis grown in pH-buffered phosphate (P)-deficient (0.5 µM) hydroponic culture supplying with 2mM nitrate (NO3 −) or ammonium (NH4 +). After 7 d treatment, elevated CO2 enhanced the biomass production of both NO3 −- and NH4 +-fed plants but decreased the P amount absorbed per weight of roots and the P concentration in the shoots of plants supplied with NH4 +. In comparison, elevated CO2 increased the amount of P absorbed per weight of roots, as well as the P concentration in plants and alleviated P deficiency-induced symptoms of plants supplied with NO3 −. Elevated CO2 also increased the root/shoot ratio, total root surface area, and acid phosphatase activity, and enhanced the expression of genes or transcriptional factors involving in P uptake, allocation and remobilization in P deficient plants. Furthermore, elevated CO2 increased the nitric oxide (NO) level in roots of NO3 −-fed plants but decreased it in NH4 +-fed plants. NO scavenger 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) inhibited plant P acquisition by roots under elevated CO2. Considering all of these findings, this study concluded that a combination of elevated CO2 and NO3 − nutrition can induce a set of plant adaptive strategies to improve P status from P-deficient soluble sources and that NO may be a signalling molecule that controls these processes.

“…So far, no per mutants have been reported to have defective polar growth in pollen tubes, probably due to the high degree of genetic redundancy between the 71 encoded apo PER III proteins in Arabidopsis (Francoz et al, 2015). Some apo PER III proteins appear to harden the cell wall structure, while others impact cell wall loosening during plant development (Passardi et al, 2006;Jin et al, 2011;Pedreira et al, 2011;Herrero et al, 2013;Kunieda et al, 2013;Shigeto et al, 2013;Manzano et al, 2014). It is unclear how these two opposite effects on cell wall polymers that are mediated by apo PER III are coordinated during the oscillatory growth cycles of these cells.…”

Other signals, such as water status, carbon monoxide, and carbon dioxide levels, also affect root hair development (Guo et al, 2009;Niu et al, 2011;Kwasniewski et al, 2016). Polar growth also is responsive to endogenous signals, such as ethylene and auxin (for review, see Lee and Cho, 2013;Velasquez et al, 2016).…”

ROS Regulation of Polar Growth in Plant Cells

ORCID ID: 0000-0001-6332-7738 (J.M.E.).Root hair cells and pollen tubes, like fungal hyphae, possess a typical tip or polar cell expansion with growth limited to the apical dome. Cell expansion needs to be carefully regulated to produce a correct shape and size. Polar cell growth is sustained by oscillatory feedback loops comprising three main components that together play an important role regulating this process. One of the main components are reactive oxygen species (ROS) that, together with calcium ions (Ca 2+ ) and pH, sustain polar growth over time. Apoplastic ROS homeostasis controlled by NADPH oxidases as well as by secreted type III peroxidases has a great impact on cell wall properties during cell expansion. Polar growth needs to balance a focused secretion of new materials in an extending but still rigid cell wall in order to contain turgor pressure. In this review, we discuss the gaps in our understanding of how ROS impact on the oscillatory Ca 2+ and pH signatures that, coordinately, allow root hair cells and pollen tubes to expand in a controlled manner to several hundred times their original size toward specific signals.

“…Also, NO donors can increase the expression of enzymes involved in methionine recycling and the ethylene biosynthetic pathway; example enzymes are SAM synthase, ACC synthase (ACS), and ACO in Arabidopsis roots (García et al 2011). In addition, CO 2 elevation could stimulate the ethylene signal transduction pathway and further induce NO signals to trigger mitogenactivated protein kinase signaling and regulate the Ca 2+ channel to control root hair development (Niu et al 2011).…”

Light-modulated seminal wavy roots in rice mediated by nitric oxide-dependent signaling

2015

Rice (Oryza sativa L.) seminal roots from germinated seeds help establish seedlings, but the seminal root growth and morphology are sensitive to environmental factors. Our previous research showed that several indica-type rice varieties such as Taichung native 1 (TCN1) showed light-induced wavy roots. Also, auxin and oxylipins are two signaling factors regulating the wavy root photomorphology. To investigate the signaling pathway, here, we found that nitric oxide (NO) was a second messenger triggering the signal transduction of light stimuli to induce the wavy morphology of seminal roots in rice. Moreover, interactions between oxylipins and phytohormones such as ethylene and auxin participating in the NO-dependent regulatory pathway of light-induced wavy roots were examined. The order of action of signaling components in the pathway was NO, oxylipins, ethylene, and auxin.
