Orthophosphate (P(i)) is an essential but limiting macronutrient for plant growth. Extensive soil P reserves exist in the form of organic P (P(o)), which is unavailable for root uptake until hydrolysed by secretory acid phosphatases (APases). The predominant purple APase (PAP) isozymes secreted by roots of P(i)-deficient (-P(i)) Arabidopsis thaliana were recently identified as AtPAP12 (At2g2719...
Despite its agronomic importance, the metabolic networks mediating phosphorus (P) remobilization during plant senescence are poorly understood. Highly efficient P remobilization (~85%) from senescing leaves and proteoid roots of harsh hakea (Hakea prostrata), a native 'extremophile' plant of south-western Australia, was linked with striking up-regulation of cell wall-localized and intracellular...
فسفر یکی از عناصر مهم و ضروری برای گیاهان محسوب می شود که در رشد، انتقال انرژی، بیوسنتز ماکرومولکول ها، فتوسنتز، تنفس سلولی و به طور کلی سوخت و ساز سلولی نقش اساسی دارد. همچنین فسفر در ترارسانی پیام و تنظیم فعالیت پروتئین ها دخالت دارد. از آنجا که گیاهان فقط قادر به جذب یون فسفات آزاد از منابع فسفر آلی و معدنی می باشند، این عنصر یکی از اصلی ترین عوامل محدود کننده رشد گیاهان به شمار می رود. بهره...
Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
Purple acid phosphatases (PAPs) play an important role in plant phosphorus nutrition, both by liberating phosphorus from organic sources in the soil and by modulating distribution within the plant throughout growth and development. Furthermore, members of the PAP protein family have been implicated in a broader role in plant mineral homeostasis, stress responses and development. We have identif...
