If such a low phosphorus concentration is an universal phenomenon during terminal Paleoproterozoic, this is likely the significant reason for limited primary productivity and therefore a low atmospheric oxygen level during that time.doi:10.1016/j.precamres.2021.106554Dongjie Tang a b...
respectively, for pO2(Table1). We note that the difference between the modern and the past Ce anomaly values determines the magnitude of the oxygen level estimate. Thus, the pO2estimate given by 5th percentiles of Ce anomaly data is lower than that calculated from 15th percentiles of data. ...
Main conclusion: This is a first comprehensive study to analyze the 12 PHT1 family phosphate transporter genes in 20 foxtail millet genotypes for the improvement of millets and other crops for phosphate use efficiency. Phosphorus (P), absorbed from soil solutions as inorganic phosphate (Pi), is...
We then tested whether expression of ALMT1 and STOP1 is regulated by Pi availability. One hour after transfer from the +Pi to −Pi medium the expression level of ALMT1 increases and reaches a plateau at 24 h (Fig. 1e). However, on both media ALMT1 expression is abrogated in strong...

Phosphorus (P), an important plant macronutrient, is a component of key molecules such as nucleic acids, phospholipids and ATP. P is often the limiting nut
Deep-water clays, in depths below the Stanley level, have grain size variations which may correlate with changing depths of water resulting from the combination of changes in lake level and elevation of the bottom. 展开 DOI: 10.1130/0016-7606(1962)73[613:LSALSO]2.0.CO;2 被引量: 58 ...
Particularly it relates to manufacturing of pipe shell of diameter from 80 till 180 mm. For providing of higher level of consumer properties with favorable relation of strength, flexibility, viscosity and minimal level of mechanical anisotropy pipe shell is implemented of steel, containing, wt %: ...
In bulk materials, most of the dopants are trapped inside the structure. However, in nanomaterials, dopants are located close to the surface and can play an active role in the reaction. Doped graphene or other nanocarbons with heteroatoms, such as oxygen, phosphorus, boron and nitrogen, have ...
