“…Since, secretion of acid phosphatase was an adaptive trait for legumes under low-P conditions which could be discerned from this study (Dutta et al 2022). Ganguly et al (2021) pointed out apart from root mediated secretions and acid phosphatase activity, other physiological and morphological changes of the roots plays critical role and helping out the plant to use soil P. Nannipieri et al (2011) elucidated that excess phosphate fertilisers could supress phosphates activity due to down-regulation of PHO genes. However, the acidifying impact of legumes are strongly correlated with BNF and biomass and not low but a congruous P-dose is the key to attain optimum enzyme activity (Tian et al 2020).…”

“…increase in rhizospheric acidification mediated P-desorption and diminution due to plant uptake and adsorption (Li et al 2015). Nonetheless, the better efficacy of Uttara in mobilising soil P-pools may be due to higher effective absorbing surface are, amount of root mediated secretions, effective foraging ability and translocation of photosynthates in the roots (Ganguly et al 2021). Also, specific strategies in legume cultivars like deposition of P and sugar in nodules than the above ground parts, efficacious N-fixation per unit of nodular mass and directly absorbing P inside nodules and bacteroids aid better P-nutrition in the deficient conditions (Araújo et al 2008).…”

“…3). Higher P-allocation vis-a-vis uptake regulated by acid and alkaline phosphates along with better source-sink relation revamped the yield of urdbean in the low-P plots as compared to the normal P-plots (Ganguly et al 2021). Grain legumes like urdbean are highly efficient in sustaining production even in low nutrient supply as because they can be used both to produce a seed crop themselves and to generate high N-content plant residue (Sinclair and Vadez 2002).…”

A field experiment was conducted during the rainy (kharif) seasons of 2019 and 2020 at ICAR-Indian Institute of Pulses Research, Kanpur, Uttar Pradesh to study the impact of soil inorganic phosphorus fractions and enzyme activity in different urdbean [Vigna mungo (L.) Hepper] cultivars. Experiment was conducted in a randomized block design (RBD) with 4 replications with two urdbean cultivars, viz. IPU-2-43 and Uttara. Experimental results suggest, higher sol-P content (6 and 14% in 2019 and 2020, respectively) under Uttara than IPU 2-43 under low P-plots whereas, no prominent change of the same was recorded under normal P-plots. Similar to sol-P, the content of Ca2-P has jumped significantly in Uttara than IPU 2-43. However, Uttara recorded higher acid and alkaline phosphatase activity as compared to IPU 2-43. In low-P plots the activity of acid phosphatase was higher by 12% (2019) and 10% (2020) in case of Uttara than IPU 2-43. Under low P soils the productivity of Uttara was significantly higher (~12% and ~9% in 2019 and 2020, respectively) than IPU 2-43. Therefore, based on the findings it can be said that with higher soluble P and productivity, the performance of Uttara was better over IPU 2-43 under low-P condition.

“…Although elevated APase activity is commonly observed in Pi‐deficient plants, previous studies have noted variations in APase activity across different genotypes within plant species, such as in rapeseed ( Brassica napus ), lentil ( Lens culinaris ), rice, soybean, and pigeonpea (Ganguly et al., 2021; Nirubana et al., 2020; Sidhu et al., 2018; Tian et al., 2003; Zhang et al., 2010). However, the underlying causes of this genotypic variation remain largely unexplored.…”

SUMMARYStylo (Stylosanthes guianensis) is a tropical legume known for its exceptional tolerance to low phosphate (Pi), a trait believed to be linked to its high acid phosphatase (APase) activity. Previous studies have observed genotypic variations in APase activity in stylo; however, the gene encoding the crucial APase responsible for this variation remains unidentified. In this study, transcriptomic and proteomic analyses were employed to identify eight Pi starvation‐inducible (PSI) APases belonging to the purple APase (PAP) family in the roots of stylo and seven in the leaves. Among these PSI‐PAPs, SgPAP7 exhibited a significantly positive correlation in its expression levels with the activities of both internal APase and root‐associated APase across 20 stylo genotypes under low‐Pi conditions. Furthermore, the recombinant SgPAP7 displayed high catalytic activity toward adenosine 5′‐diphosphate (ADP) and phosphoenolpyruvate (PEP) in vitro. Overexpression (OE) of SgPAP7 in Arabidopsis facilitated exogenous organic phosphorus utilization. Moreover, SgPAP7 OE lines showed lower shoot ADP and PEP levels than the wild type, implying that SgPAP7 is involved in the catabolism and recycling of endogenous ADP and PEP, which could be beneficial for plant growth in low‐Pi soils. In conclusion, SgPAP7 is a key gene with a major role in stylo adaptation to low‐Pi conditions by facilitating the utilization of both exogenous and endogenous organic phosphorus sources. It may also function as a PEP phosphatase involved in a glycolytic bypass pathway that minimizes the need for adenylates and Pi. Thus, SgPAP7 could be a promising target for improving tolerance of crops to low‐Pi availability.
