“…The protection of HO-1 against oxidative damage has been demonstrated in wheat ( Huang et al, 2006 ; Xie et al, 2008 ; Wu et al, 2011 ), soybean ( Noriega et al, 2004 ; Yannarelli et al, 2006 ), Arabidopsis ( Xie et al, 2011 , 2012 ), and alfalfa ( Han et al, 2008 ). Furthermore, HO-1 also participates in developmental processes in plants such as root formation ( Xuan et al, 2008 ; Cao et al, 2011 ; Lin et al, 2012 ) and seed germination ( Xu et al, 2011 ). The effect of auxin on adventitious root formation in cucumber is realized by rapidly activating the activity of HO, which in turn results in the HO product, CO, thereby triggering signal transduction events ( Xuan et al, 2008 ).…”

Cereal aleurone layers undergo a gibberellin (GA)-regulated process of programmed cell death (PCD) following germination. Heme oxygenase-1 (HO-1) is known as a rate-liming enzyme in the degradation of heme to biliverdin IXα, carbon monoxide (CO), and free iron ions (Fe2+). It is a critical component in plant development and adaptation to environment stresses. Our previous studies confirmed that HO-1 inducer hematin (Ht) promotes the germination of rice seeds in drought (20% polyethylene glycol-6000, PEG) conditions, but the corresponding effects of HO-1 on the alleviation of germination-triggered PCD in GA-treated rice aleurone layers remain unknown. The present study has determined that GA co-treated with PEG results in lower HO-1 transcript levels and HO activity, which in turn results in the development of vacuoles in aleurone cells, followed by PCD. The pharmacology approach illustrated that up- or down-regulated HO-1 gene expression and HO activity delayed or accelerated GA-induced PCD. Furthermore, the application of the HO-1 inducer Ht and nitric oxide (NO) donor sodium nitroprusside (SNP) not only activated HO-1 gene expression, HO activity, and endogenous NO content, but also blocked GA-induced rapid vacuolation and accelerated aleurone layers PCD under drought stress. However, both HO-1 inhibitor zinc protoporphyrin IX (ZnPPIX) and NO scavenger 2-(4-carboxyphenyl0-4, 4,5,5-tetramethylimidazoline-l-oxyl-3-oxide potassium salt (cPTIO) reserved the effects of Ht and SNP on rice aleurone layer PCD under drought stress by down-regulating endogenous HO-1 and NO, respectively. The inducible effects of Ht and SNP on HO-1 gene expression, HO activity, and NO content were blocked by cPTIO. Together, these results clearly suggest that HO-1 is involved in the alleviation of GA-induced PCD of drought-triggered rice aleurone layers by associating with NO.

“…Additionally, H 2 O 2 metabolism related proteins or other target proteins responsible for LR formation might be regulated by β -CDH at transcriptional and translational levels. Combined with the inducing responses in adventitious root development elicited by β -CDH ( Lin et al, 2012 ), our results thus provided a comprehensive window of the complex signaling transduction pathway in β -CDH-mediated root organogenesis.…”

“…Although the role of respiratory burst oxidase homologs (RBOH)-mediated H 2 O 2 as a second messenger in root organogenesis has been extensively illustrated ( Li et al, 2007 , 2009 ; Cao et al, 2014 ; Ma et al, 2014 ; Orman-Ligeza et al, 2016 ), it was not known whether H 2 O 2 could act as an intermediate in β -CDH-induced LR formation. Meanwhile, several important downstream signaling components, including NO and HO-1 ( Bai et al, 2012 ; Lin et al, 2012 ; Cao et al, 2014 ; Fang et al, 2014 ; Ma et al, 2014 ; Li et al, 2015 ), are shared in some aspects of β -CDH- and H 2 O 2 -induced root organogenesis. These results suggested the possibility that a linear pathway from β -CDH to H 2 O 2 may exist in LR formation.…”

Although previous results showed that β-cyclodextrin-hemin complex (β-CDH) could induce tomato lateral root (LR) formation, the corresponding downstream messengers are still not fully understood. In this report, similar to the inducing effects of exogenously applied hydrogen peroxide (H2O2), we discovered that β-CDH elicited RBOH1 transcript upregulation, endogenous H2O2 accumulation, and thereafter tomato LR development. Above responses were sensitive to dimethylthiourea (DMTU) and ascorbic acid (AsA), two membrane-permeable scavengers of H2O2, showing that accumulation of H2O2 and LR formation were significantly blocked. The test with diphenyleneiodonium (DPI; the inhibitor of NADPH oxidase) revealed that H2O2 mainly produced by NADPH oxidase, might be involved in LR formation triggered by β-CDH. qPCR combined with pharmacological and anatomical analyses showed that β-CDH-modulated several marker genes responsible for LR formation, such as CYCA3;1, CYCA2;1, CYCD3;1, and CDKA1 (four cell cycle regulatory genes), ARF7 and RSI-1 (two auxin signaling genes), LAX3 (an auxin influx carrier), IAA14 (encoding a member of the Aux/IAA protein family), PIN3 and PIN7 (two auxin efflux carriers), isocitrate dehydrogenase [NADP], NADH-cytochrome b5 reductase 1, and L-ascorbate oxidase homolog genes (two reactive oxygen species-associated genes and one LR formation-related gene), were causally related to above H2O2 signaling. Particularly, representative proteins related to H2O2 metabolism and lateral rooting, were specifically induced in β-CDH-treated tomato seedlings. Overall, the results clearly suggested a vital role of H2O2 in the β-CDH-induced tomato LR formation, and β-CDH-elicited H2O2-related target proteins responsible for LR formation might be, at least partially, regulated at transcriptional and translational levels.

“…The Olea europaea alternative oxidase gene OeAOX2 is highly expressed in AR primordia (Peixe et al, 2007) and its activity is highly induced during adventitious rooting in cuttings (Macedo et al, 2009). The heme oxygenase-1 gene HO-1 is involved in adventitious rooting in cucumber via the regulation of the HO-1-mediated target genes, such as DNAJ-like and the gene encoding calcium-dependent protein kinase (CDPK) (Lin et al, 2012).…”

The formation of adventitious roots (ARs) is an ecologically and economically important developmental process in plants. The evolution of AR systems is an important way for plants to cope with various environmental stresses. This review focuses on identified genes that have known to regulate the induction and initiation of ARs and offers an analysis of this process at the molecular level. The critical genes involved in adventitious rooting are the auxin signaling-responsive genes, including the AUXIN RESPONSE FACTOR (ARF) and the LATERAL ORGAN BOUNDARIES-DOMAIN (LOB) gene families, and genes associated with auxin transport and homeostasis, the quiescent center (QC) maintenance, and the root apical meristem (RAM) initiation. Several genes involved in cell wall modulation are also known to be involved in the regulation of adventitious rooting. Furthermore, the molecular processes that play roles in the ethylene, cytokinin, and jasmonic acid signaling pathways and their crosstalk modulate the generation of ARs. The crosstalk and interaction among many molecular processes generates complex networks that regulate AR generation.
