In recent years,nitric oxid.(NO)has emerged.as a k.y red.x signaling molecule in plants functioning in the regulation of k.y d.velopmental programs and.the orchestration of responses to a plethora of environmental cues(k.lbert et al.,2019).The pred.minant route for the transfer of NO bioactivity is through S-nitrosylation,the ad.ition of an NO moiety to a protein cysteine thiol to form an S-nitrosothiol(Yun et al.,2011).Specificity for this process is established.by the structural constraints imposed.by tertiary protein structure in gating access to given cysteine red.x switches and.associated.proteins that can either facilitate the ad.ition or removal of the NO moiety at these resid.es(Umbreen et al.,2018).

A new route to weak.force sensing beyond.SQL: Squeezed.magnons in cavity magnomechanics

Quantum mechanics imposes limits on measurement accuracy through quantum noise which typically has two components: First is the shot noise originating from vacuum fluctuations and.referred.to as the imprecision noise. Second.is the quantum back.ction originating from the “action” of the measurement back.on the object being measured. The balance between the imprecision noise and.the quantum back.ction(QBA) noise impose a stand.rd.quantum limit(SQL)on the quality of measurement [1].
