Nitrogen is a critical life element and a major component of amino acids, nucleic acids, and other important biomolecules. Plants cannot directly use atmospheric nitrogen gas. Thus, nitrogen in the soil is transformed through the nitrogen cycle....
Lastly, denitrification is the conversion of nitrates to the atmospheric form of nitrogen, which will be released from the soil to the atmosphere. The nitrogen cycle is essential since it allows plants to use nitrogen that allows them to synthesize chlorophyll for thei...
We quantified temporal variations in carbon (C) and nitrogen (N) content, starch, fructan and total soluble sugars in leaves, stem bases and roots of F. paniculata during one growth cycle in mown and unmown fields and related them to the dynamics of soil mineral N concentration and soil ...

form a heterodimer. The TIM/PER complex enters the nucleus and then promotes the phosphorylation of CLK/CYC, which inhibits the promotion of theperandtimmRNAs. During the day, TIM and PER are gradually degraded, and consequently, CLK/CYC are released from repression to start a new cycle. ...
