The phrase "act as essential" is not correct in standard written English.
It may be intended to convey the idea of something being crucial or necessary, but the phrasing is awkward and unclear.
Example: "The new software will act as essential for improving our workflow." (This should be rephrased for clarity.)
Alternatives: "serve as crucial" or "function as necessary."
Previous studies suggest that GRAS transcription factors act as essential regulators, not only in plant growth and development but also in response to biotic and abiotic stresses.
DAG and PA are two interconvertible lipids that influence membrane architecture and that act as essential signaling molecules that activate various downstream effectors, including master regulators of local protein synthesis and actin polymerization.
Although most secondary compounds are deterrent to the vast majority of species, there are some cases in which these compounds act as essential sign stimuli for an animal, indicating that it has the correct food.
Thus, the let-7 miRNAs of C. elegans and D. melanogaster both act as essential regulators for proper development at the larva-to-adult transition.
Although the two dimensions of work-family balance practices are different in their content, formats and effects, they ultimately act as essential resources provided by organizations.
The surprises didn't stop at small ncRNAs, and an expanding body of evidence reveals that long non-coding RNAs (lncRNAs, >200 nucleotides in length), once were described as 'dark matter', act as essential regulators in diverse cellular progresses.
This is in line with reports that GA acts as essential hormone in promoting germination and negatively regulating ABA levels [ 57, 58].
Indeed, we demonstrate the amplitude of per mRNA oscillation is severely dampened in 50 day old flies and levels of per mRNA are significantly reduced at late night, when PER acts as essential element of clock negative feedback loop [ 11].
Abscisic acid is known to inhibit germination and the expression of photosynthesis-related genes in imbibed seeds [ 54] while GA acts as essential hormone in promoting germination and etiolated development while negatively regulating ABA levels [ 57, 58] in a process that is dependent on BRs [ 59].
Throughout the book she weaves the insight that the freedom to reverse any act of artistic making is as essential as the freedom to create.
In contrast, manganese, iron, and cobalt act mainly as essential micronutrients, but their occurrence at high levels can represents a potentially serious hazard for environmental health [20].
