“…Taken together, an extensive understanding of the nature of plant–pathogen interaction under drought stress would be needed in cases where trichomes enhance pathogen growth. Mapping for leaf pubescence related QTLs have been done for many plants like Gossypium hirsutum and A. thaliana (Lacape and Nguyen, 2005; Bloomer et al, 2014). It can be hypothesized that enhancement of trichome production impart protection against combined drought and pathogen infection in many cases and trichomes can be considered as a potential morpho-physiological trait conferring tolerance to the stress combination.…”

Global warming leads to the concurrence of a number of abiotic and biotic stresses, thus affecting agricultural productivity. Occurrence of abiotic stresses can alter plant–pest interactions by enhancing host plant susceptibility to pathogenic organisms, insects, and by reducing competitive ability with weeds. On the contrary, some pests may alter plant response to abiotic stress factors. Therefore, systematic studies are pivotal to understand the effect of concurrent abiotic and biotic stress conditions on crop productivity. However, to date, a collective database on the occurrence of various stress combinations in agriculturally prominent areas is not available. This review attempts to assemble published information on this topic, with a particular focus on the impact of combined drought and pathogen stresses on crop productivity. In doing so, this review highlights some agriculturally important morpho-physiological traits that can be utilized to identify genotypes with combined stress tolerance. In addition, this review outlines potential role of recent genomic tools in deciphering combined stress tolerance in plants. This review will, therefore, be helpful for agronomists and field pathologists in assessing the impact of the interactions between drought and plant-pathogens on crop performance. Further, the review will be helpful for physiologists and molecular biologists to design agronomically relevant strategies for the development of broad spectrum stress tolerant crops.

“…It is therefore possible that system 2 ethylene production is not the only mechanism contributing to the autocatalytic regulation of climacteric ethylene. Recent data showed that ethylene biosynthesis displays a tissue-specific and developmental differentiation throughout tomato fruit growth, indicating that it is organized and regulated in a well-defined tissue-specific way (Van de Poel et al, 2014).…”

Ethylene control of fruit ripening: revisiting the complex network of transcriptional regulation

(M.L.); 0000-0002-5725-885X (J.P.); 0000-0001-7707-7776 (J.-P.R.).The plant hormone ethylene plays a key role in climacteric fruit ripening. Studies on components of ethylene signaling have revealed a linear transduction pathway leading to the activation of ethylene response factors. However, the means by which ethylene selects the ripening-related genes and interacts with other signaling pathways to regulate the ripening process are still to be elucidated. Using tomato (Solanum lycopersicum) as a reference species, the present review aims to revisit the mechanisms by which ethylene regulates fruit ripening by taking advantage of new tools available to perform in silico studies at the genomewide scale, leading to a global view on the expression pattern of ethylene biosynthesis and response genes throughout ripening. Overall, it provides new insights on the transcriptional network by which this hormone coordinates the ripening process and emphasizes the interplay between ethylene and ripening-associated developmental factors and the link between epigenetic regulation and ethylene during fruit ripening.As a developmental process, fruit ripening is coordinated by a complex network of endogenous and exogenous cues. Indeed, the making of a fruit is a genetically regulated process unique to plants involving three distinct stages: fruit set, development, and ripening. Fruit development is characterized by a series of developmental transitions tightly coordinated by a network of interacting genes and signaling pathways. Among these, ripening has received the greatest attention from both geneticists and breeders. From the scientific point of view, fruit ripening is seen as a process in which the biochemistry and physiology of the organ are developmentally altered to influence the appearance, texture, flavor, and aroma (Giovannoni, 2004). Since most of the fruit sensory and nutritional quality traits are elaborated at the ripening stage, deciphering the key genetic and molecular factors regulating ripening becomes a major task toward improving overall fruit quality (Carrari and Fernie, 2006). In addition, the control of fruit ripening is also instrumental to maintain the quality attributes of the fruit during the postharvest shelf life.Based on their mode of ripening, fleshy fruits are divided into two categories, climacteric and nonclimacteric, depending on the presence or absence of the climacteric rise in respiration and of autocatalytic ethylene production (Lelièvre et al., 1997). In climacteric fruit, the plant hormone ethylene is the major cue that controls most aspects of ripening. By contrast, the ripening of nonclimacteric fruit does not strictly depend on ethylene, and the nature of the triggers of ripening in this type of fruit remains yet to be elucidated. Since the upstream components of the ethylene transduction pathway are common to all ethylene responses, the apparent simplicity of the ethylene signaling pathway cannot account for the wide diversity of ethylene responses. A plausible hypothesis is that dif...

“…A targeted metabolomics and proteomics study by Van de Poel et al (2014b) investigated the tissue specificity of the ethylene biosynthesis pathway in tomato fruit. They observed that the pericarp tissue produced the highest amount of ethylene (and high ACO activity), while the pericarp had the lowest ACS activity and ACC content compared to other tissues.…”

1-aminocyclopropane-1-carboxylic acid (ACC) in plants: more than just the precursor of ethylene!

Ethylene is a simple two carbon atom molecule with profound effects on plants. There are quite a few review papers covering all aspects of ethylene biology in plants, including its biosynthesis, signaling and physiology. This is merely a logical consequence of the fascinating and pleiotropic nature of this gaseous plant hormone. Its biochemical precursor, 1-aminocyclopropane-1-carboxylic acid (ACC) is also a fairly simple molecule, but perhaps its role in plant biology is seriously underestimated. This triangularly shaped amino acid has many more features than just being the precursor of the lead-role player ethylene. For example, ACC can be conjugated to three different derivatives, but their biological role remains vague. ACC can also be metabolized by bacteria using ACC-deaminase, favoring plant growth and lowering stress susceptibility. ACC is also subjected to a sophisticated transport mechanism to ensure local and long-distance ethylene responses. Last but not least, there are now a few exciting studies where ACC has been reported to function as a signal itself, independently from ethylene. This review puts ACC in the spotlight, not to give it the lead-role, but to create a picture of the stunning co-production of the hormone and its precursor.
