“…Interestingly, this was associated with up-regulation of NbPR1a transcripts but without ROS generation and HR [58]. This compound was later also demonstrated to increase resistance against P. infestans in potatoes, but, as in many other cases for potato the resistance was associated with ROS generation and lesion formation [101]. …”

This review provides a current summary of plant resistance inducers (PRIs) that have been successfully used in the Solanaceae plant family to protect against pathogens by activating the plant’s own defence. Solanaceous species include many important crops such as potato and tomato. We also present findings regarding the molecular processes after application of PRIs, even if the number of such studies still remains limited in this plant family. In general, there is a lack of patterns regarding the efficiency of induced resistance (IR) both between and within solanaceous species. In many cases, a hypersensitivity-like reaction needs to form in order for the PRI to be efficient. “-Omics” studies have already given insight in the complexity of responses, and can explain some of the differences seen in efficacy of PRIs between and within species as well as towards different pathogens. Finally, examples of field applications of PRIs for solanaceous crops are presented and discussed. We predict that PRIs will play a role in future plant protection strategies in Solanaceae crops if they are combined with other means of disease control in different spatial and temporal combinations.

“…Several applications using potato suspension cells have been reported for studies of plant stress responses. For example, leaf-derived potato suspension cells were used to study resistance to osmotic stress (Sabbah and Tal, 1990) and to measure accumulation of phytoalexins (Brindle et al, 1983), biosynthesis of oxylipins (Stumpe et al, 2001), nitric oxide and ROS production (Sapko et al, 2011), and expression of defense-related genes (Monjil et al, 2014). Most notably, exposure of suspension cells established from potato leaf protoplasts to cutin monomers induces alkalinization, production of ethylene, and transcriptional up-regulation of the defense-related genes (Schweizer et al, 1996).…”

Extracellular Alkalinization as a Defense Response in Potato Cells

et al. 2017

A quantitative and robust bioassay to assess plant defense response is important for studies of disease resistance and also for the early identification of disease during pre- or non-symptomatic phases. An increase in extracellular pH is known to be an early defense response in plants. In this study, we demonstrate extracellular alkalinization as a defense response in potatoes. Using potato suspension cell cultures, we observed an alkalinization response against various pathogen- and plant-derived elicitors in a dose- and time-dependent manner. We also assessed the defense response against a variety of potato pathogens, such as protists (Phytophthora infestans and Spongospora subterranea) and fungi (Verticillium dahliae and Colletotrichum coccodes). Our results show that extracellular pH increases within 30 min in proportion to the number of pathogen spores added. Consistently with the alkalinization effect, the higher transcription level of several defense-related genes and production of reactive oxygen species was observed. Our results demonstrate that the alkalinization response is an effective marker to study early stages of defense response in potatoes.

“…Monjil et al found that a synthetic bis-aryl-methanone compound (NUBS-4190) and a methanol extract from a pathogen (the mycelia of P. infestans) that contained lipophilic compounds were elicited by potato leaves in response to NO. 169,170) The gene for Arabidopsis thaliana nitric oxide-associated 1 (AtNOA1) has been identified as a putative regulator of NOS activity in plants. 171) In N. benthamiana leaves, the pathogenesis-related 1a (NbPR1a) gene and nitric oxide associated 1 (NbNOA1) gene, a homolog of AtNOA1, were found to be associated with infection resistance.…”

Nitrogen is a very common element, comprising approximately 78% of Earth’s atmosphere, and is an important component of various electronic devices while also being essential for life. However, it is challenging to directly utilize dinitrogen because of the highly stable triple bond in this molecule. The present review examines the use of non-equilibrium plasmas to generate controlled electron impacts as a means of generating reactive nitrogen species (RNS) with high internal energy values and extremely short lifetimes. These species include ground state nitrogen atoms, excited nitrogen atoms, etc. RNS can subsequently react with oxygen and/or hydrogen to generate new highly reactive compounds and can also be used to control various cell functions and create new functional materials. Herein, plasma-processing methods intended to provide RNS serving as short-lived precursors for a range of applications are examined in detail.
