“…In (b), plants were grown for 10 days on MGRL agar media supplemented with 1500 µM (+S) or 15 µM sulfate (-S). Plants were then transferred to +S or -S hydroponic medium containing 32 Furthermore, we analyzed the Pi uptake using the radioactive isotope of phosphorus ( 32 P) ( [45,46], Figure 2b). Plants grown for 10 days on +S or -S agar media were transferred to +S or -S hydroponic solution containing 32 P. After 60 min, the intensity of 32 P were significantly higher in plants subjected to -S comparing to that subjected to +S (Figure 2b), indicating an enhancement of Pi uptake as an early response to -S.…”

Recent studies have shown various metabolic and transcriptomic interactions between sulfur (S) and phosphorus (P) in plants. However, most studies have focused on the effects of phosphate (Pi) availability and P signaling pathways on S homeostasis, whereas the effects of S availability on P homeostasis remain largely unknown. In this study, we investigated the interactions between S and P from the perspective of S availability. We investigated the effects of S availability on Pi uptake, transport, and accumulation in Arabidopsis thaliana grown under sulfur sufficiency (+S) and deficiency (−S). Total P in shoots was significantly increased under −S owing to higher Pi accumulation. This accumulation was facilitated by increased Pi uptake under −S. In addition, −S increased root-to-shoot Pi transport, which was indicated by the increased Pi levels in xylem sap under −S. The −S-increased Pi level in the xylem sap was diminished in the disruption lines of PHT1;9 and PHO1, which are involved in root-to-shoot Pi transport. Our findings indicate a new aspect of the interaction between S and P by listing the increased Pi accumulation as part of −S responses and by highlighting the effects of −S on Pi uptake, transport, and homeostasis.

“…In the case of P starvation, other signaling compounds come into play, including P itself, inositol polyphosphate, miRNAs, photosynthates, and calcium (Ruffel, 2018). Recently, a redlight signaling in the regulation of nutrient uptake and use was suggested, as it was found that expression levels of P starvationresponsive genes in Arabidopsis were modulated by PIF4/PIF5 and HY5 transcription factors, which activity is under the control of phytochromes (Sakuraba et al, 2018).…”

“…Based on recent literature data, we summarised our results in a model according to which the light intensity controls allocation of sugars between the shoot and the root (Fig. 3SA, supplement; Sakuraba et al 2018, van Gelderen et al 2018aZhou et al 2019). Under BRS light, a redirection of assimilates occurs towards the shoot and for flowering.…”

“…3SA). Different studies demonstrated that high light intensity and red light can indeed promote nutrient assimilation and induce specific signaling cascades from the shoot to the root which promote root development, as well as exudation of organic acids in the rhizosphere (Cheng et al 2014, Sakuraba et al 2018, van Gelderen et al 2018aZhou et al 2019). These discoveries revealed that light is not only involved in the synthesis and transportation of sugars Fig.…”

“…but acts as a signal regulating root morphology. It has been suggested that the stimulatory effect of red light signaling on phosphorus uptake is apparent upon phosphorus deficit (Sakuraba et al 2018). In the lower intensity BRS light variant, the blue light input is decreased compared to the W control, which could lead to slower nutrients assimilation.…”

Light is a major factor controlling plant growth and development. To assess the impact of the applied light conditions, we aimed to sort out a tool for early diagnostics of the plant physiological state. We investigated the effect of a blue:red:far-red LED light formula recommended for improved plant performance (flowering). High (BR) and low (BRS) light intensity variants were compared to normal (W) and 'shadowed' (WS) white fluorescent controls. The efficiency of the JIP-test to determine changes during early growth of pea plants was compared to additional physiological characteristics (growth parameters, thermal stability of the thylakoid membranes, chlorophyll content, CO2 assimilation, transpiration). Our data showed the onset of growth inhibition under BR light, while BRS light stimulated plants to reach the flowering stage similarly as the W control. We concluded that the JIP-test is appropriate for early, reliable, and nondestructive analysis of light recipes for plant growth and flowering.
