Scheme 9.1 Advantages
of administration of
exogenous NO-releasing
nanomaterials in agriculture
In the past,
S
-nitrosylation has been the most studied NO-dependent regulatory
mechanism. In summary,
S
-nitrosylation is a redox-based mechanism for cysteine
residue modification and is being recognized as ubiquitous regulatory reaction
comparable to phosphorylation. Then, it is emerging as a crucial mechanism for
the transduction of NO bioactivity in plants and animals (Romero-Puertas
et al.
2013
). Recently, a mini-review reported an overview on
S
-nitrosylation of
target proteins related to hormone networks in plants (Par
´
s et al.
2013
).
Till now, a few reports on the combination of NO donors with nanomaterials in
agriculture have been available. In this context, the present chapter will discuss the
importance of administration of exogenous NO donors in plants, the impact of
nanotechnology in agriculture, and the necessity to develop new strategies based on
NO-releasing nanomaterials in agriculture. Therefore, we hope that this chapter will
open new perspectives in the field of nanotechnology, NO, and agriculture.

modulated and improved by treating plants with NO-releasing nanomaterials.
9.2 Role of Exogenous NO Donors on Plants
NO donors are extensively used in animals in a great variety of biomedical
applications (Seabra and Dur´n
2010
,
2012
; Carpenter and Schoenfisch
2012
).
However, in plants, its use is very restricted to few reports. Application of NO
donors in plants might result in several advantages for agriculture, and it needs to be
more explored in the near future. This section highlights the beneficial aspects of
applications of exogenous NO donors in several aspects of plant growth and
defense.
