“…Previous studies (Pagnussat , Pagnussat et al , , Lanteri et al , , Xuan et al , , Li et al ) and our pilot experiments showed that the concentrations and the time of treatments with above mentioned chemicals are suitable for investigating the role of NO in the adventitious root developmental signalling. Especially, excised cucumber hypocotyls (5‐mm‐long segments of the hypocotyl base, where adventitious root develops) (Lanteri et al ) were used for the following analysis.…”

Our previous studies revealed that methane (CH ) induces adventitious rooting in cucumber. However, the corresponding molecular mechanism is still elusive. In this work, we discovered that CH triggered the accumulation of nitric oxide (NO) and thereafter cucumber adventitious rooting, mimicking the inducing effects of sodium nitroprusside (SNP) and NONOate (two NO-releasing compounds). Above mentioned responses were sensitive to NO scavenger(s), showing that the accumulation of NO and adventitious root development were respectively impaired. Inhibitor test and biochemical analysis suggested that endogenous NO mainly produced by mammalian NO synthase-like enzyme and diamine oxidases (DAO), might be required for adventitious root formation elicited by CH . Molecular evidence confirmed that CH -mediated induction of several marker genes responsible for adventitious root development, including CsDNAJ-1, CsCDPK1, CsCDPK5, cell division-related gene CsCDC6, and two auxin signaling genes, CsAux22D-like and CsAux22B-like, was casually dependent on NO signaling. The possible involvement of S-nitrosylation during the mentioned CH responses was preliminarily illustrated. Taken together, through pharmacological, anatomical and molecular approaches, it is suggested that NO might be involved in CH -induced cucumber adventitious rooting, and CH -eliciated NO-targeted proteins might be partially modulated at transcriptional and post-translational levels. Our work may increase the understanding of the mechanisms underlying CH -elicited root organogenesis in higher plants.

“…40 The relationship between endogenous HO-1/CO and NO during adventitious rooting was also proposed. 41 Thus, a network presented here shows that H 2 might regulate HO-1/ CO pathway through NO pathway during adventitious rooting. On the other hand, H 2 might induce adventitious root development directly in a NO-independent manner.…”

“…Additionally, sodium nitroprusside (SNP) was used as a NO-releasing compound [30][31][32][33]. 2-(4-Carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide potassium salt (cPTIO) was regarded as a scavenger of NO [51][52][53][54]. Tungstate (Tg; an inhibitor of NR [28,33,37,[55][56][57];) and N G -nitro-L-arginine methyl ester hydrochloride (NAME; an inhibitor of mammalian NOS-like enzyme [25,33,[36][37][38][39];) were also applied.…”

A Novel Mechanism Underlying Multi-walled Carbon Nanotube-Triggered Tomato Lateral Root Formation: the Involvement of Nitric Oxide

Abundant studies revealed that multi-walled carbon nanotubes (MWCNTs) are toxic to plants. However, whether or how MWCNTs influence lateral root (LR) formation, which is an important component of the adaptability of the root system to various environmental cues, remains controversial. In this report, we found that MWCNTs could enter into tomato seedling roots. The administration with MWCNTs promoted tomato LR formation in an approximately dose-dependent fashion. Endogenous nitric oxide (NO) production was triggered by MWCNTs, confirmed by Greiss reagent method, electron paramagnetic resonance (EPR), and laser scanning confocal microscopy (LSCM), together with the scavenger of NO. A cause-effect relationship exists between MWCNTs and NO in the induction of LR development, since MWCNT-triggered NO synthesis and LR formation were obviously blocked by the removal of endogenous NO with its scavenger. The activity of NO generating enzyme nitrate reductase (NR) was increased in response to MWCNTs. Tungstate inhibition of NR not only impaired NO production, but also abolished LR formation triggered by MWCNTs. The addition of N G-nitro-L-arginine methyl ester (L-NAME), an inhibitor of mammalian nitric oxide synthase (NOS)-like enzyme, failed to influence LR formation. Collectively, we proposed that NO might act as a downstream signaling molecule in MWCNT control of LR development, at least partially via NR.
