“…4.3 | Substitution of P i with P from organic fertiliser hardly change ClaPHT1 members expression PHT1 genes encode high-affinity P i transporters to participate in P i acquisition, and the majority of PHT1 genes are expressed in both roots and shoots (Wang, Hoffland, Feng, & Kuyper, 2017;Yang, Zhao, & Wang, 2020). This study showed that ClaPHT1;2, ClaPHT1;4 and ClaPHT1;5 expression did not change in roots (Figure 6h,i,k) or leaves (Figure 7f,g,h) when P i was partially substituted by P from organic fertiliser.…”

Application of organic fertilisers is beneficial to the quality and yield of crops. Myoinositol phosphate is an abundant form of organic phosphorus (P o ) in organic manure and soil, which could release phosphate (P i ) and likely be absorbed by plant after it was hydrolysed by phytase. However, whether plant roots respond to organic fertiliser to adapt myo-inositol phosphates utilisation is not clear. Experiments were carried out to investigate the responses of phytase gene expression and enzyme activity, as well as root architecture to organic fertiliser application. The results showed that Cow-dung-based organic fertiliser contains 2.30 g/kg soluble P, including 0.08 g/kg myo-inositol phosphates P. Organic acid addition promotes myo-

Moso bamboo typically grows in phosphorus (P)-deficient soil that limits the growth and development. In this study, ten Moso bamboo genotypes (Ph-1 to Ph-10) were evaluated for their responses to P deficiency during the seedling stage by growing them in both P-sufficient and P-deficient conditions. Adaptive responses to low P conditions were observed in the majority of genotypes. Under P deficiency conditions, total biomass decreased in several genotypes, but at the same time the root-to-shoot ratio (R/S) increased. Principal components analysis identified two main comprehensive traits (PC1 and PC2) related to root volume and surface area and P concentration and accumulation. Based on the analysis, two genotypes (Ph-6 and Ph-10) were identified with significantly different levels of tolerance to P deficiency. The results revealed that the genotype Ph-10 responded to P deficiency by significantly increasing root surface area and volume, while simultaneously reducing the number of root cortex cells when compared to the genotype Ph-6, which showed the lowest tolerance (intolerant). The genotype Ph-10 exhibited a robust response to external low-P conditions, marked by elevated expression levels of PHTs and SPXs. In-situ PCR analysis also revealed distinct tissue-specific expression patterns of the genes in the roots, particularly highlighting differences between Ph-6 and Ph-10. The results provide a foundation for elucidating the mechanism of low-P tolerance, thus potentially contributing to developing high P use efficiency (PUE) in Moso bamboo species.

Phosphorus (P) fertilizer is generally applied to enhance the soil P pool and meet crop demand, but most of the added P is absorbed by soil. This study aimed to explore the importance of P fractions and adsorption–desorption characteristics on the demand for P fertilizer to determine the optimum P fertilizer amount for a cotton field under mulched drip irrigation in Xinjiang, China. A 4-year experiment (2016–2019) was conducted in a cotton field to evaluate the effects of five P fertilizer addition levels (0, 75, 150, 300, and 450 kg P2O5 ha−1 year−1) on inorganic P fractions and P adsorption–desorption properties at different soil depths and explore the effects of soil properties on P adsorption. The 4-year continuous P fertilization enhanced the inorganic P content and altered the proportions of various P forms. A large proportion of P accumulated in soil was transformed into Ca8-P, followed by Ca2-P, mainly in the surface layer. The accumulation and transformation of P in fertilized soil reduced P adsorption and enhanced P desorption. Soils with higher P application levels had higher inorganic P accumulation with lower adsorption and higher desorption. The total P and Olsen-P in a 0- to 5-cm soil layer; Ca8-P and calcium carbonate (CaCO3) in a 5- to 10-cm soil layer; Olsen-P, Ca10-P, clay, and cation exchange capacity in a 10- to 20-cm soil layer; and Olsen-P in a 20- to 40-cm soil layer significantly affected the P adsorption–desorption (p < 0.05). The application rate of 75–150 kg P2O5 ha−1 year−1 produced lower inorganic P accumulation, favorable adsorption–desorption properties, and high cotton yield, and thus could be considered the optimal P fertilizer application level.
