Effects of Phosphorus Deficiency on ion transport and its correlation with sugar content and anatomical structure in chickpea (Cicer arietinum L. cv. Bari chola-5) seedlings
Dhaka University Journal of Biological Sciences, 2014Co-Authors: Amatun Karim, Parveen Rashid, Rafat Samad, Jl KarmokerAbstract:Phosphorus Deficiency stimulated accumulation of Na+ in the root but declined in the shoot of chickpea seedlings. K+ content in the root and the shoot increased initially followed by a decrease. Phosphorus Deficiency inhibited the accumulation of NO 3‐ , PO 4 3‐ and also sugar content both in the root and shoot. It also caused a decline in the accumulation of total sugar only in the root. The interrelationship between the effect of Phosphorus Deficiency on ion transport and anatomical structure was discussed. DOI: http://dx.doi.org/10.3329/dujbs.v23i2.20095 Dhaka Univ. J. Biol.

Effects of Phosphorus Deficiency on accumulation of biochemical compounds in lentil ( Lens culinaris Medik.)
Bangladesh Journal of Botany, 2011Co-Authors: Bimal Chandra Sarker, Jl KarmokerAbstract:Phosphorus Deficiency caused a decrease in the accumulation of reducing sugar in the leaves and stems but increased in the roots of lentil ( Lens culinaris Medik.). Accumulation of insoluble protein was depressed in lentil following P-Deficiency. Phosphorus Deficiency increased proline and phenolic compounds in roots and stems and anthocyanin in leaves compared to control. Key words: Phosphorus Deficiency; Accumulation; Biochemical compounds DOI: http://dx.doi.org/10.3329/bjb.v40i1.7992 Bangladesh J. Bot. 40 (1): 23-27, 2011 (June)

Effects of Phosphorus Deficiency on anatomical structures in maize (Zea mays L.).
Bangladesh Journal of Botany, 2010Co-Authors: Bimal Chandra Sarker, Jl Karmoker, Parveen RashidAbstract:Anatomical response of maize ( Zea mays L.) to Phosphorus Deficiency grown in sand culture and half strength Hoagland solution revealed that Phosphorus Deficiency caused a decrease in diameter of the root and stem as well as thickness of the leaf. Epidermal cells of the root, stem and leaf became thickened, cortical zone of root and stem was reduced, endodermal and pericycle cells became smaller and thick walled in Phosphorus deficient plants. The prominent structural changes due to Phosphorus Deficiency occurred in the vascular system where the vascular area is decreased with less number of xylem vessels and smaller size of the cavity. Phosphorus Deficiency also resulted in decreased number and smaller sized stomata in leaves. Key words: Phosphorus Deficiency; Anatomy; Maize; Zea mays L. DOI: 10.3329/bjb.v39i1.5527 Bangladesh J.

Bangladesh Journal of Botany, 2010Co-Authors: Bimal Chandra Sarker, Jl KarmokerAbstract:Phosphorus Deficiency resulted in an increase in the length of primary root, length and number of lateral roots, root hairs and root meristem volume of the seedlings of lentil grown in rhizobox.

The Effect of Phosphorus Deficiency Stress on Fluorescence Parameter and Chromosome of Wheat Substitution Lines
2013Co-Authors: Li Cun-dongAbstract:Wheat substitution lines between Chinese Spring and Synthetic 6x under the treatments of Phosphorus Deficiency stress and Phosphorus normal(control)in different developing stages were studied to research the effect of Phosphorus Deficiency stress on fluorescence parameters and locate the gene controlling fluorescence parameters.The results showed that Fm,Fv/Fm reduced and Fo increased under Phosphorus Deficiency stress in different developing stages;The genes regulating Fo might be located on 3D chromosome of Synthetic 6x,and that the genes regulating Fm might be located on 3B chromosome and the genes regulating Fv/Fm might be located on 3B,7D chromosome.

Effects of Phosphorus Deficiency Stress on Protective Enzyme Activities,MDA Content and Chromosome of Wheat Substitution Lines Seedling Roots
2013Co-Authors: Li Cun-dongAbstract:The effects of Phosphorus Deficiency stress on enzyme activity in wheat was studied by determining antioxidant enzymes SOD,POD activities and MDA content and locating the gene controlling antioxidant enzymes SOD,POD activities and MDA content at the roots of the seedling stage using wheat substitution lines between Chinese Spring(CS)and Synthetic 6x.The results showed that SOD and POD activities increased,MDA content reduced under Phosphorus Deficiency stress.This explains that the increased of antioxidant enzyme activity might reduce MDA content and lower membrane lipid peroxidation level,to improve their resistance.The genes promoting SOD activity might be located on 3A,4A,5A and 7A chromosome of Synthetic 6x;and the genes promoting POD activity might be located on 5A,1D and 2D chromosome,while the genes inhibiting content might be located on 5A,2D,5D and 7D chromosome of Synthetic 6x.

Anatomical changes of lentil (Lens culinaris Medik.) under Phosphorus Deficiency stress
Bangladesh Journal of Botany, 2015Co-Authors: Bimal Chnadra Sarker, Parveen Rashid, Jl JarmokerAbstract:Phosphorus Deficiency in lentil ( Lens culinaris Medik.) resulted in the development of abundant long root hairs which were rudimentary in plants fed with Phosphorus. Root and stem diameter as well as thickness of leaf reduced under Phosphorus Deficiency. The cortical zone of the stem and root was found to decrease under Phosphorus Deficiency. Vascular area became smaller with less number of xylem vessels and smaller size of the cavity due to Phosphorus Deficiency. The pith area was increased in the stem under Phosphorus deficient condition. DOI: http://dx.doi.org/10.3329/bjb.v44i1.22726 Bangladesh J. Bot. 44 (1): 73-78, 2015 (March)

effects of Phosphorus Deficiency and adenosine 5 triphosphate atp on growth and cell cycle of the dinoflagellate prorocentrum donghaiense
Harmful Algae, 2015Co-Authors: Xinguo Shi, Lingxiao Lin, Senjie LinAbstract:Abstract Phosphorus (P) is one of the major nutrients required for growth of phytoplankton. While dissolved inorganic Phosphorus (DIP) is the preferred form of P, phytoplankton can utilize dissolved organic Phosphorus (DOP) when DIP is limited. How DIP Deficiency affects the progression of the cell division cycle and how well DOP can restore normal cell cycle in phytoplankton is unclear. Here we investigated the effects of DIP limitation and supply of adenosine 5′-triphosphate (ATP) as sole P-source on the growth and cell cycle in Prorocentrum donghaiense, one of the most common harmful algae bloom dinoflagellates in East China Sea. Part of the culture under DIP-replete condition progressed through a complete cell cycle (G1 → S → G2M) in 24 h with a typical diel rhythm of each phase, exhibiting a daily growth rate of 0.40 d−1 and average cell size 11.19 ± 0.06 μm in equivalent spherical diameter. Under Phosphorus Deficiency, population growth of P. donghaiense averaged at 0.09 d−1 and the cell cycle was blocked in G1 phase, while cell size averaged at 11.65 ± 0.05 μm. When DIP was replaced by ATP at equivalent molar concentration, the cultures displayed similar growth rate, cell size, and cell cycle oscillation as in the DIP-replete treatment. The results suggest that Phosphorus Deficiency blocks the cell cycle due to the inability to complete DNA duplication or check-point protein phosphorylation while still allowing photosynthesis and metabolisms, and that DOP such as ATP can fully complement DIP in P. donghaiense.
