“…Recently, it has been reported that overexpression of AtPAP17 in soybean improves PUE in transgenic plants. This observation is in line with the altered PUE results presented in the present study (Xu et al, 2022). Overall, the result supports that compensatory acid phosphatases are activated to minimize the impact of the loss of PAP17 orthologs on Pi nutrition in plants.…”

The scarcity of soil phosphorus (P), an essential macronutrient, often limits plant growth and development. Enhanced secretion of intracellular and secretory acid phosphatases is essential to maintain cellular inorganic P (Pi) homeostasis in plants. Herein, using transcriptomics and proteomics approach, we observed upregulation of several purple acid phosphatases (PAPs), includingSlPAP1,SlPAP10b,SlPAP12,SlPAP15,SlPAP17b,SlPAP26a, andSlPAP26bin Pi-deficient tomato seedlings. Higher transcript levels ofSlPAP17bandSlPAP26bin the older senescing leaves than the younger leaves indicated active involvement of these PAPs in Pi remobilization. Subsequent detailed characterization ofSlPAP17b,SlPAP26a, andSlPAP26brevealed a prominent role ofSlPAP26bin Pi homeostasis. Silencing ofSlPAP26bled to an exacerbated P starvation response as these plants exhibited smaller shoots, lower soluble Pi, total P levels, and higher sucrose than their EV controls under Pi deprivation.SlPAP26b-silenced plants also showed misregulation of P starvation inducible genes such as phosphate transporters and glycerolipid remodellers, even under Pi-sufficient conditions. WhereasSlPAP26blevels were induced by external sucrose, its expression was found to be independent of the Myb class master regulators of P starvation response, SlPHR1 and SlPHL1. Altogether, this study identifies a prominent role ofSlPAP26bin the Pi compensation network in tomato seedlings.

“…The expression of LaPAP12 increases secretion of the acid phosphatases from the roots of white lupine (Lupinus albus), thus improving the availability of soil P. 48 A newly identified gene, GmPAP17, significantly enhanced the tolerance to low P stress by increasing APase activity and P use efficiency. 49 In our study, under the Low P treatment, Mo application increased the expression of GmPAP18a and GmPAP27a. At the Normal P treatment, Mo application increased the expression of GmPAP26a, GmPAP29, and GmPAP22a (Tables S8 and S9), among which GmPAP26a, GmPAP18a, and GmPAP27a are secretory acid phosphatase-related genes.…”

While molybdenum (Mo) application can improve phosphorus (P) availability to plants by changing P speciation in the rhizosphere, the mechanistic basis of this process remains unclear. This work investigated the impact of various combinations of Mo and P treatments on root morphology, P and Mo uptake, and root transcriptome and metabolome. Mo application significantly increased soybean biomass and the number of lateral roots at both low (5 μmol) or normal (500 μmol) P levels and significantly improved P concentration and accumulation in Normal P treatment. Compared with the Normal P treatment, Low P significantly increased the number of roots, root surface area, and root acid phosphatase secretion. A total of 6811 Mo-responsive differentially expressed genes and 135 differential metabolites were identified at two P levels. At Low P, transcriptional changes significantly increased root synthesis and secretion of succinic acid, methylmalonic acid, and other organic acids as well as acid phosphatase, thereby increasing the conversion of soil aluminum-bound P and organic P into available P. At Normal P, Mo application increased P uptake mainly by increasing the number of lateral roots. Thus, Mo helps crops adapt to different P levels by regulating root anatomy and transcriptional and metabolic profiles of their roots.

“…It was also reported that the PAP interacts with other genes to alleviate the effect of drought stress on Arabidopsis (.e.g. AtGAL1 ) (Ghahremani et al 2019 ) and wild plants ( RAP2 .2)(H. Xu et al 2022 ; Zhang et al 2008 ). The strong association between the biological function of candidate genes and drought tolerance indicates the successfulness of our GWAS in identifying markers associated with yield traits under drought stress in rice.…”

Drought has a significant impact on rice yield by restricting the crop's ability to grow and develop. Producing rice cultivars adapted to water deficit conditions is still the main interest of rice breeders and geneticists. To address this challenge, a set of 413 highly diverse rice populations were evaluated under normal and water deficit conditions for two growing seasons of 2021 and 2022. High genetic variation was found among genotypes for all studied traits. The heritability estimates ranged from 0.82 (panicle length) to 0.95 (plant height). Sterility percentage (SET%) was the most trait affected by water deficit in two growing seasons. 22 Rice genotypes were classified as drought tolerant in both years. Genome-wide association mapping was performed for all traits in the two growing seasons under both conditions using a total of 700,000 SNPs. The GWAS results revealed important and major SNPs associated with all traits. 26 Significant SNPs with stable allele effects were found to be associated with yield traits under water deficit conditions in both years. The results of this study provided rice genotypes that can be adapted under water deficit conditions and important stable SNP markers that can be used for marker-assisted selection after validation in different genetic backgrounds.
