In recent years,nitric oxide(NO)has emerged as a key redox signaling molecule in plants functioning in the regulation of key developmental programs and the orchestration of responses to a plethora of environmental cues(Kolbert et al.,2019).The predominant route for the transfer of NO bioactivity is through S-nitrosylation,the addition 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 redox switches and associated proteins that can either facilitate the addition or removal of the NO moiety at these residues(Umbreen et al.,2018).

With rapid advancements in Infra-Red (IR) detection techniques, the range from where the IR-guided missiles are able to lock the target aircraft has increased. To avoid the detection and tracking by modern IR-guided missiles, the aircraft and helicopters also demand progress in its stealth techniques. Hence, study of Infra-Red Signature Suppression (IRSS) systems in aircraft and helicopters has become vital even in design stage. Optical blocking (masking) is one of the effective IRSS techniques used to block the Line- Of-Sight (LOS) of the hot engine parts of the exhaust geometry. This paper reviews the various patents on IR signature suppression systems based on the optical blocking method or a combination of IRSS techniques. The performance penalties generated due to installation of various IRSS methods in aircraft and helicopters are also discussed.
