“…This indicates that even since the early phenological stages, the AsV might limit the ability of the seedling to grow as adult plants. Similar reductions in the development of plumules and the leaf area have been reported in both species monocotyledonous as Triticum aestivum [34], Oryza sativa [35,36] and dicotyledonous as Cucumis sativus [37], Lepidium sativum [38], Acacia auriculiformis [39], Helianthus annum [40]. In the case of the root length, significant reductions were found at low AsV concentrations, but in the cultivar Alina the roots .…”

Due to its geological origin and the intense agro-industrial activity, regions whose vocation is the agri-food production present a high level of contamination by heavy metals as the arsenic that induces toxicity in the crops of economic importance as in the case of barley (Hordeum vulgare L.). The evaluation of the response of different cultivars and genotypes in the first phenological stages is indispensable to generate technical information regard the tolerance to arsenic and the same time theoretical knowledge about how this metal is absorbed. The aim of this study was to evaluate the physiological response of barley seedlings to arsenic V (AsV) toxicity and deduce how this metal could be absorbed by the plants. Seedlings of the cultivars Alina and Esperanza were evaluated under the concentrations of 100, 200, 500 and 700 mg L -1 . Besides, models for the proteins PHT1 and HvHMA1 were performed by homology with affinity assays for AsV. The seedlings of Alina presented higher degree of tolerance to the toxicity whereby potentially the productive plots of this cultivar Alina could tolerate higher concentrations of this heavy metal. Also, the AsV could be transported by its competence with the endogenous ions as Mg 2 + and PO4 3-.

“…Plants must take up sufficient amount of P to balance excessive As for the alleviation of As toxicity. The plants react to As exposure by increasing P accumulation (Burlo et al, 1999;Leimu and Fischer, 2008;Khan et al, 2013;Khan et al, 2018).…”

“…Areas under turnip cultivation in Bangladesh are prone to the risk. Being a toxic element, As poses serious threats to environment and human health (Leimu and Fischer, 2008;Singh et al, 2015;Babst-Kostecka et al, 2016;Guevara-Garcia et al, 2017;Khan et al, 2018). When crops are grown in As-contaminated soil or irrigated with As-contaminated water, As gets accumulated in the seeds or grain which is becoming an increasingly important problem in many parts of the world (Sanal et al, 2014) as it poses significant risk to animal and human health through soil-crop transfer (Fitz and Wenzel, 2002;Sultana et al, 2015).…”

Arsenic (As) is a toxic metalloid widely distributed in the environment posing threat to human health. Enriching the soil with phosphorus (P) in As condition is believed to reduce the uptake of As in plants. But, it is not clear whether this uptake changes affect the growth behaviors of plant or not. Therefore, this study was conducted to determine the efficacy of P in balancing the negative effects of As on Brassica rapa. Seeds of B. rapa were treated with different concentrations of As, with or without addition of P. As exposure hindered seed germination and seedling growth at different magnitudes depending on the level of concentrations. However, addition of P in As solution culture improved the seed germination and seedling growth significantly. Germination were 87% in T2 (2 ppm As + 10 ppm P), 78% in T4 (5 ppm As + 10 ppm P) and 68% in T6 (10 ppm As + 10 ppm P) compared to 82% in T1 (2 ppm As), 73% in T3 (5 ppm As) and 61% in T5 (10 ppm As).In treatments T1, T3 and T5, seedling dry biomasses were 26 mg, 15 mg and 12 mg respectively, which were enhanced to 31 mg, 21 mg and 16 mg respectively in T2, T4 and T6. Similar trend was also recorded for plumule and radical growth, seedling vigor, sturdiness etc. Therefore, this study recommended the application of P to reduce the negative effects of As on B. rapa in As solution culture and maintains that the results may hold good in the field.

“…To resolve the tissue-P imbalance, P is remobilized from old plant organs (roots, shoots, and leaves), translocated, and stored into seeds during filling stages (Plénet et al, 2000). The P contained in the seeds constitutes an important supply for the plants at the germination stage (Khan et al, 2018). Greater P concentration is observed in young leaves at earlier stages of plant growth for better leaves formation and role in cell division which stimulates the growth of leaves and roots in size and depth (Kavanová et al, 2006;Malhotra et al, 2018).…”

Phosphate-Dependent Regulation of Growth and Stresses Management in Plants

The importance of phosphorus in the regulation of plant growth function is well studied. However, the role of the inorganic phosphate (Pi) molecule in the mitigation of abiotic stresses such as drought, salinity, heavy metal, heat, and acid stresses are poorly understood. We revisited peer-reviewed articles on plant growth characteristics that are phosphorus (P)-dependently regulated under the sufficient-P and low/no-P starvation alone or either combined with one of the mentioned stress. We found that the photosynthesis rate and stomatal conductance decreased under Pi-starved conditions. The total chlorophyll contents were increased in the P-deficient plants, owing to the lack of Pi molecules to sustain the photosynthesis functioning, particularly, the Rubisco and fructose-1,6-bisphosphatase function. The dry biomass of shoots, roots, and P concentrations were significantly reduced under Pi starvation with marketable effects in the cereal than in the legumes. To mitigate P stress, plants activate alternative regulatory pathways, the Pi-dependent glycolysis, and mitochondrial respiration in the cytoplasm. Plants grown under well-Pi supplementation of drought stress exhibited higher dry biomass of shoots than the no-P treated ones. The Pi supply to plants grown under heavy metals stress reduced the metal concentrations in the leaves for the cadmium (Cd) and lead (Pb), but could not prevent them from absorbing heavy metals from soils. To detoxify from heavy metal stress, plants enhance the catalase and ascorbate peroxidase activity that prevents lipid peroxidation in the leaves. The HvPIP and PHO1 genes were over-expressed under both Pi starvation alone and Pi plus drought, or Pi plus salinity stress combination, implying their key roles to mediate the stress mitigations. Agronomy Pi-based interventions to increase Pi at the on-farm levels were discussed. Revisiting the roles of P in growth and its better management in agricultural lands or where P is supplemented as fertilizer could help the plants to survive under abiotic stresses.
