Innate immunity in Arabidopsis thaliana: lipopolysaccharides activate nitric oxide synthase (NOS) and induce defense genes.
TLDR
It is shown that Arabidopsis thaliana reacts to LPS with a rapid burst of NO, a hallmark of innate immunity in animals and contributes toward the activation of plant defense responses.

Pentacyclic Triterpenoids from the Medicinal Herb, Centella asiatica (L.) Urban
TLDR
The biosynthesis of the centelloid triterpenoids is reviewed; the range of metabolites found in C. asiatica, together with their known biological activities and the chemotype variation in the production of these metabolites due to growth conditions are summarized.

Characterisation of two phenotypes of Centella asiatica in Southern Africa through the composition of four triterpenoids in callus, cell suspensions and leaves
TLDR
The triterpenoids from leaf tissue were more easily quantifiable in each phenotype than in the case of the undifferentiated cells (callus and cell suspensions), which had lower, but still quantifiable, levels of these targeted secondary metabolites.

Analyses of chlorogenic acids and related cinnamic acid derivatives from Nicotiana tabacum tissues with the aid of UPLC-QTOF-MS/MS based on the in-source collision-induced dissociation method
TLDR
The UHPLC-Q-TOF-MS/MS fingerprinting method was used and the regio- and geometric-isomer profiles of chlorogenic acids of the two tissue types of Nicotiana tabacum were achieved and the method was also shown to be applicable for the detection of other related molecules containing a cinnamic acid core.

Assessment of a simple, non-toxic Alamar blue cell survival assay to monitor tomato cell viability.
TLDR
The AB assay showed a sigmoidal relationship between cell viability and AB reduction (as quantified by spectrofluorometry or spectrophotometry), which was similar to that obtained using the conventional 2,3,5-triphenyltetrazolium chloride (TTC) viability assay.

Self/nonself perception and recognition mechanisms in plants: a comparison of self-incompatibility and innate immunity.
TLDR
Analyses of emerging concepts indicate that parallels exist between self-incompatibility and pathogen recognition and that evolution may have driven expansion of certain RLK families to serve roles in particular physiological processes, this may not exclude these receptor types from functioning in different programs.

Lipopolysaccharides from Burkholderia cepacia contribute to an enhanced defensive capacity and the induction of pathogenesis-related proteins in Nicotianae tabacum
TLDR
The LPS were found to possess activity as elicitors of plant defense responses in tobacco where the induction of PR-proteins was investigated by selective low pH extraction and electrophoretic analyses and indicative of an enhanced defensive capacity due to pre-conditioning by the bio-active LPS.

Early perception responses of Nicotiana tabacum cells in response to lipopolysaccharides from Burkholderia cepacia
Lipopolysaccharides (LPS) are cell surface components of Gram-negative bacteria and, as microbe- / pathogen-associated molecular patterns, have diverse roles in plant–microbe interactions, e.g. LPS…
