“…Similarly, stomata in SA-deficient Arabidopsis nahG (27) or eds16 (115) plants do not respond to PAMPs (77). The defect in PAMP/bacterium-triggered stomatal closure in SA-deficient plants is interesting, as previous studies have shown that SA is a potent inducer of stomatal closure (66,75,83). Taken together, these results suggest mechanistic connections between PAMP signaling, SA homeostasis, and ABA homeostasis and signaling in guard cell response to bacteria.…”

Pathogen entry into host tissue is a critical first step in causing infection. For foliar bacterial plant pathogens, natural surface openings, such as stomata, are important entry sites. Historically, these surface openings have been considered as passive portals of entry for plant pathogenic bacteria. However, recent studies have shown that stomata can play an active role in limiting bacterial invasion as part of the plant innate immune system. As counter-defense, the plant pathogen Pseudomonas syringae pv. tomato DC3000 uses the virulence factor coronatine to actively open stomata. In nature, many foliar bacterial disease outbreaks require high humidity, rain, or storms, which could promote stomatal opening and/or bypass stomatal defense by creating wounds as alternative entry sites. Further studies on microbial and environmental regulation of stomatal closure and opening could fill gaps in our understanding of bacterial pathogenesis, disease epidemiology, and microbiology of the phyllosphere.

“…Concentrations above 0.01 mM of MJ were reported to inhibit root growth in some species (Lois et al 1989). Treatment with 5 mM SA showed a 25 % reduction in the growth of Vicia faba L. after 7-day incubation (Manthe et al 1992). Exogenously applied SA has been shown to affect a variety of processes in plants, including stomatal closure, seed germination, fruit yield, and glycolysis (Klessig and Malamy 1994).…”

Background: Bilobalide and ginkgolides are reported to be present only in Ginkgo biloba. However, only trace amounts of bilobalide and ginkgolides are contained in the ginkgo leaves. Nowadays, there has been considerable interest in plant cell cultures as a potential alternative to traditional agriculture for the industrial production of secondary metabolites. Much effort has been put into the use of in vitro cultures as one attractive biotechnological strategy for producing bilobalide and ginkgolides of commercial interest. The aim of this study was to enhance the production of bilobalide and ginkgolides A, B, and C in cell cultures of G. biloba using immobilized cell cultures and the process of elicitation.Results: Based on the effect of the immobilization components on the free cell suspension cultures, it was considered that the jute fiber acted as an elicitor and forced the cells to release the product into the culture media. The resulting biomass was approximately 1.4 times higher than in the cell suspension cultures, and the production of bilobalide and ginkgolides A, B, and C increased 5.0, 3.3, 6.1, and 4.1 times, respectively. Eliciting with methyl jasmonate (MJ) and salicylic acid (SA) in the immobilized cells enhanced bilobalide and ginkgolides A, B, and C, compared with the unelicited controls. The highest accumulation was observed using a combination of 0.1 mM MJ + 0.1 mM SA in the immobilized cells, which produced 1.78, 1.95, 2.05, and 2.95 times more bilobalide and ginkgolides A, B, and C, respectively, than the controls. Conclusions:The positive effects of immobilized cell cultures using jute fiber and the synergism effect of SA and MJ on immobilized cells of G. biloba appear to be the optimal conditions for continuous in vitro production for commercial purposes. This is the first report on analyzing the effects of jute fiber as immobilized cell material on G. biloba cell cultures and the synergism of MJ and SA on bilobalide and ginkgolide production.

“…Interestingly, rapid closure of stomata and an increase in foliar H 2 O 2 have been shown to occur upon SA treatment of leaves (Manthe et al, 1992;Chen et al, 1993;Rao et al, 1997;Shirasu et al, 1997;Lee, 1998;Mori et al, 2001). This may be associated with SA-dependent inhibition of CAT activity (Sanchez-Casas and Klessig, 1994;Conrath et al, 1995;Durner and Klessig, 1996;Chen et al, 1997).…”

The lsd1 mutant of Arabidopsis fails to limit the boundaries of hypersensitive cell death response during avirulent pathogen infection and initiates unchecked lesions in long day photoperiod giving rise to the runaway cell death (rcd) phenotype. We link here the initiation and propagation of rcd to the activity of photosystem II, stomatal conductance and ultimately to photorespiratory H 2 O 2 . A cross of lsd1 with the chlorophyll a/b binding harvesting-organelle specific (designated cao) mutant, which has a reduced photosystem II antenna, led to reduced lesion formation in the lsd1/cao double mutant. This lsd1 mutant also had reduced stomatal conductance and catalase activity in short-day permissive conditions and induced H 2 O 2 accumulation followed by rcd when stomatal gas exchange was further impeded. All of these traits depended on the defense regulators EDS1 and PAD4. Furthermore, nonphotorespiratory conditions retarded propagation of lesions in lsd1. These data suggest that lsd1 failed to acclimate to light conditions that promote excess excitation energy (EEE) and that LSD1 function was required for optimal catalase activity. Through this regulation LSD1 can influence the effectiveness of photorespiration in dissipating EEE and consequently may be a key determinant of acclimatory processes. Salicylic acid, which induces stomatal closure, inhibits catalase activity and triggers the rcd phenotype in lsd1, also impaired acclimation of wild-type plants to conditions that promote EEE. We propose that the roles of LSD1 in light acclimation and in restricting pathogen-induced cell death are functionally linked.
