“…ROS accumulation, induction of plant innate immunity, resistance to B. cinerea, and increased cuticular permeability have been observed in A. thaliana and Solanum lycopersicum mutants of cutin monomers biosynthesis (Serrano et al 2014). Thus, we questioned whether eca2 was a cuticular mutant.…”

“…Once pathogens degrade and penetrate the cuticle, different chemical components are released, including DAMPs and MAMPs, which are potentially perceived by the invading fungi and by the plant, activating multiple processes during pathogenesis. Several reports have shown that Arabidopsis thaliana and Solanum lycopersicum mutants affected in the synthesis of cutin monomers display increased cuticle permeability, induction of the plant innate immunity, and resistance to Botrytis cinerea (Serrano et al 2014). One hypothesis to explain these responses is that once B. cinerea spores have landed on the more permeable leaf surface, molecules such as MAMPs and DAMPs can be, one or both, more rapidly or efficiently recognized leading to the establishment of plant innate immunity.…”

We isolated previously several Arabidopsis thaliana mutants with constitutive expression of the early microbe-associated molecular pattern–induced gene ATL2, named eca (expresión constitutiva de ATL2). Here, we further explored the interaction of eca mutants with pest and pathogens. Of all eca mutants, eca2 was more resistant to a fungal pathogen (Botrytis cinerea) and a bacterial pathogen (Pseudomonas syringae) as well as to a generalist herbivorous insect (Spodoptera littoralis). Permeability of the cuticle is increased in eca2; chemical characterization shows that eca2 has a significant reduction of both cuticular wax and cutin. Additionally, we determined that eca2 did not display a similar compensatory transcriptional response, compared with a previously characterized cuticular mutant, and that resistance to B. cinerea is mediated by the priming of the early and late induced defense responses, including salicylic acid– and jasmonic acid–induced genes. These results suggest that ECA2-dependent responses are involved in the nonhost defense mechanism against biotrophic and necrotrophic pathogens and against a generalist insect by modulation and priming of innate immunity and late defense responses. Making eca2 an interesting model to characterize the molecular basis for plant defenses against different biotic interactions and to study the initial events that take place in the cuticle surface of the aerial organs.

“…In many plants, including the model plant Arabidopsis, the epidermis is a cell monolayer, although in some plant species (such as Ficus and Peperomia) multi-layered epidermis can be observed in mature organs (Araújo et al, 2013;Horner, 2012;Wuyts et al, 2010). The epidermis acts as a physical barrier and a platform for the perception of external signals (SavaldiGoldstein et al, 2007;Serrano et al, 2014;Sieber et al, 2000;Wang et al, 2011;Xia et al, 2010). In this respect, the plant shoot epidermis shows remarkably strong parallels ( Fig.…”

Plant aerial epidermal tissues, like animal epithelia, act as loadbearing layers and hence play pivotal roles in development. The presence of tension in the epidermis has morphogenetic implications for organ shapes but it also constantly threatens the integrity of this tissue. Here, we explore the multi-scale relationship between tension and cell adhesion in the plant epidermis, and we examine how tensile stress perception may act as a regulatory input to preserve epidermal tissue integrity and thus normal morphogenesis. From this, we identify parallels between plant epidermal and animal epithelial tissues and highlight a list of unexplored questions for future research.

“…It is also a source of signals used by invading fungi to activate pathogenic responses or by plants to induce defense mechanisms [1][2][3]. Recent observations have been made to reveal complex inter-relationships between cuticular lipids and plant defense [4]. Cuticular lipids consist of fatty acids (FAs).…”

The leaf surface of higher plants is composed of varied profile of hydrocarbons which play a vital role in chemical recognition and potentially involved in plant-pathogen interactions and communication with nature. There is little evidence to the direction that plant cuticle play a major factor in plant defense against pathogens besides imparting physical barrier to the plant. Teak (Tectona grandis. L) is one such tree found with diverse geographical distribution. In the present work, our objective was to study the cuticular composition of the fresh leaves of teak which is responsible for its wide adaptation and its antimicrobial activity. Cuticular compounds from the hexane fraction of the teak leaves were isolated, purified and spectral analyses revealed a long chain unbranched heneicosane (C 21 ) with a mol. wt. of 296. This saturated hydrocarbon forms a continuous layer on the leaf surfaces which act as physical barrier to the micro-organisms and also possesses a strong defensing activity against a number of pathogens which implies its role in defensive mechanisms of the plant. The antifungal activity of heneicosane on each of the microbial species was statistically significant at P≤0.001 level. Its abundant recovery from teak leaves may justify its putative role as a resistance marker.
