Special Issue: Plant Genetics and Biotechnology in Biodiversity

Diversity (2018)

Giandomenico Corrado Rosa Rao

The rapid progress and increasing affordability of novel investigation tools in plant genetics and biotechnology offer previously inaccessible opportunities for the exploitation of plant genetic diversity in agriculture. The Special Issue was lunched to highlight how new technologies are improving both genotyping and phenotyping methods, thus allowing us to uncover crop diversity and use genetic variability for plant breeding with remarkable precision and speed. Three thematic reviews report on scientific, technological, and legal advances in plant diversity and agriculture. Three contributions provide specific examples of the exploitation of different kinds of genetic resources, ranging from landraces to mutant populations. Six research articles are illustrative examples of the study of molecular and/or phenotypic diversity to address basic or applied questions in different plant species. Finally, this SI was also launched to honor the memory of Prof. Gian Tommaso Scarascia Mugnozza and a dedicated Editorial acknowledges his work in plant breeding and biodiversity protection.

Systemin-inducible defence against pests is costly in tomato

Biologia Plantarum (2011)

Giandomenico Corrado Diana Agrelli Mariapina Rocco Boris Basile Mauro Marra

The possible costs of inducible defences against pests were evaluated in tomato. To activate inducible resistance traits, we used transgenic plants that over-expressed the systemin precursor (prosystemin). The constitutive expression of the prosystemin, which is normally induced by herbivores in tomato, allowed the measurement of the impact of induced defences in a pest-free environment. The results showed that the continuous activation of traits that are normally induced by pests should be costly, affecting the growth, physiology and reproductive success of tomato plants.

Effects of Time of Pruning and Plant Bio-Regulators on the Growth, Yield, Fruit Quality, and Post-Harvest Losses of Ber (Ziziphus mauritiana)

Horticulturae (2022)

Shashi Shashi Om Prakash Garhwal Mali Ram Choudhary Laxmi Narayan Bairwa K.L. Kumawat

Indian jujube or ber (Ziziphus mauritiana Lam.) is a deciduous fruit tree typically cultivated in several semi-arid areas of Asia because of its adaptability to yield-limiting conditions. The present study aimed to assess the effect of four pruning times (i.e., the fourth week of March, second week of April, fourth week of April, and second week of May) and four treatments using stress-mitigating plant bio-regulators (thiourea at 500 ppm and 1000 ppm; salicylic acid at 100 ppm and 150 ppm) as a means to improve both fruit yield and quality post-harvest. To this end, a full factorial experiment lasting two growing seasons was carried out under field conditions in the representative semi-arid region of Rajasthan, the state with the largest production in India. We assessed the vegetative growth of the trees, the fruit size and yield, and some quality parameters (soluble content, acidity, ascorbic acid, and total sugars) as well as the main post-harvest traits (fruit weight loss and spoilage). Overall, pruning during the second week of April had the greatest positive influence on most of the variables studied. For instance, it induced the highest vegetative vigor, allowing the maintenance of relatively higher chlorophyll and relative water content in the leaves. The fruit parameters also responded most positively to the second week of April pruning, a treatment that, compared to the others, induced a higher diameter; a higher amount of TSS (19.6 °Brix), ascorbic acid (86.5 mg/100 g), and total sugar (10.4%); and a better post-harvest shelf-life. Among the plant bio-regulators, the application of thiourea at 1000 ppm had the highest positive influence on the growth parameters, yield, quality, and reduction in spoilage post-harvest. The differences between the doses of PBRs were limited.

Accumulation of Ascorbic Acid in Tomato Cell Culture: Influence of the Genotype, Source Explant and Time of In Vitro Cultivation

Antioxidants (2020)

Maria Minutolo Pasquale Chiaiese Antonio Di Matteo A. Errico Giandomenico Corrado

The production and commercialization of natural antioxidants is gaining increasing importance due to their wide range of biological effects and applications. In vitro cell culture is a valuable source of plant bioactive compounds, especially those highly dependent on environmental factors. Nonetheless, research on the accumulation in plant cultured cells of water-soluble antioxidant vitamins, such as the ascorbic acid (AsA), is very limited. Tomato fruits are a main dietary source of vitamin C and in this work, we explored the potential of in vitro cultured cells for AsA accumulation. Specifically, using a full factorial design, we examined the effect of the source explant, the time in tissue culture and the genetic difference present in two Introgression Line (IL7-3 and IL12-4) that harbor Quantitative Trait Loci (QTLs) for ascorbic acid in fruits. Moreover, we performed an expression analysis of genes involved in AsA metabolism to highlight the molecular mechanisms that can account for the difference between fruit explants and calli. Our work indicated that cultured tomato cells accumulate AsA well beyond the amount present in fruits and that the three factors under investigation and their interaction significantly influence AsA accumulation. The time in tissue culture is the main single factor and, different from the expectations for secondary metabolites, explants from unripe, mature green fruits provided the highest increase in AsA. Moreover, in controlled conditions the genetic differences between the ILs and the control genotype are less relevant for calli cultivated for longer time. Our work showed the potential of tomato cell culture to produce AsA and prompt further refinements towards its possible large-scale exploitation.

Authentication of the ‘Annurca’ Apple in Agro-food Chain by Amplification of Microsatellite Loci

Food Biotechnology (2007)

D. Melchiade I. Foroni Giandomenico Corrado I. Santangelo Rosa Rao

An increasing application of DNA fingerprinting in modern food biotechnology is the authentication of species and cultivars in commercial edible products. In this work we describe the genetic authentication of apple fruits from "Annurca" and "Annurca Rossa del Sud", the leading varieties of the Italian Campania region, in two different highly-processed foodstuffs, nectar and purée. The identification was based on fluorescent-based capillary electrophoresis and automated size estimation of polymorphic DNA microsatellites. We selected 4 Simple Sequence Repeats (SSRs) able to distinguish 17 different apple accessions. Each SSR proved to be suitable to authenticate the presence of Annurca as ingredient in the analysed apple derivatives. This study represents the first application of DNA technology to the identification of apple cultivars in the agro-food chain.

Configuration by Osmotic Eustress Agents of the Morphometric Characteristics and the Polyphenolic Content of Differently Pigmented Baby Lettuce Varieties in Two Successive Harvests

Horticulturae (2021)

Giandomenico Corrado Paola Vitaglione Georgios A. Soteriou Marios C. Kyriacou Youssef Rouphael

Salinity eustress is one of the pre-harvest factors that can be used to improve the phytochemical profile and the quality attributes of horticultural species, and most of the studies are carried out using NaCl. In this work, we compared the effect of three mildly saline iso-osmotic nutrient solutions (NS) differing in the cation employed (either K, Na, or Ca) in baby lettuce cultivated in a floating system. Specifically, we analyzed the impact on key morphological traits and polyphenol composition in leaves in a completely randomized design experiment with the following experimental factors and levels: two differently pigmented lettuce varieties (green and full red), three NSs (20 mM KCl, 20 mM NaCl, 13.3 mM CaCl2, each with a final ionic concentration of 40 mM), and two successive harvests. The lettuce response to mild salinity was multifaceted and with a marked role for the cultivar factor and its interactions, as also indicated by multivariate analysis. The morphological response of baby lettuce to the saline solutions was predominantly affected by the osmolarity, and ion-specific alleviating or detrimental effects were not observed. The phytochemical analysis revealed significant interactions among all tested factors, with ion-specific differences over some of the detected phenolics. This is consistent with the high sensitivity of this class of bioactive compounds to environmental factors. This work indicated that certain combinations of the experimental factors tested can be exploited to improve the biochemical profile and possibly the nutraceutical quality of baby lettuce in a floating system.

The Genetic Diversity and Structure of Tomato Landraces from the Campania Region (Southern Italy) Uncovers a Distinct Population Identity

Agronomy (2021)

Martina Caramante Youssef Rouphael Giandomenico Corrado

Italy is one of the main producers and processors of tomato and it is considered a secondary center of diversity. In some areas, such as the Campania region (Southern Italy), a range of traditional tomato landraces is still cultivated. The distinction of this heritage germplasm is often based only on folk taxonomy and a more comprehensive definition and understanding of its genetic identity is needed. In this work, we compared a set of 15 local landraces (representative of traditional fruit types) to 15 widely used contemporary varieties, using 14 fluorescent Simple Sequence Repeat (SSR) markers. Each of the accessions possessed a unique molecular profile and overall landraces had a genetic diversity comparable to that of the contemporary varieties. The genetic diversity, multivariate, and population structure analysis separated all the genotypes according to the pre-defined groups, indicating a very reduced admixture and the presence of a differentiated (regional) population of landraces. Our work provides solid evidence for implementing conservation actions and paves the way for the creation of a premium regional brand that goes beyond the individual landrace names of the Campania region known throughout the world.

Trichoderma and Phosphite Elicited Distinctive Secondary Metabolite Signatures in Zucchini Squash Plants

Agronomy (2021)

Luigi Formisano Begoña Miras‐Moreno Michele Ciriello Christophe El‐Nakhel Giandomenico Corrado

Plant biostimulants are “green” solutions to improve crop production. Trichoderma spp. and phosphites, ordinarily used as biocontrol agents, can trigger phytostimulation, also promoting endogenous mechanisms involved in plant growth and development. The present study aimed at assessing the efficacy of a phosphite-based formulation (Phosphit-One) and Trichoderma harzianum-T22 on the morpho-physiological response and modulation of the metabolomics profile in zucchini squash plants (Cucurbita pepo L.) cultivated in controlled growth conditions (Fitotron®). The highest values of fresh biomass production (390.9 g plant−1) and root dry weight (5.6 g plant−1) were obtained for Trichoderma-treated plants. This last treatment resulted in an improved physiological performance (SPAD index, CO2 assimilation rate, and Fv/Fm ratio) measured 30 days after transplanting. Both Trichoderma and phosphite treatments induced a broad metabolic reprogramming in leaves, evident also for the phosphite treatment that did not result in a growth promotion. The microbial and the non-microbial treatments showed distinctive signatures in secondary metabolism yet, common responses could be also highlighted. For instance, both Trichoderma and phosphite triggered ROS-mediated signaling processes, together with the accumulation of phenylpropanoids, glucosinolates, and phytoalexins. Furthermore, a significant alteration of phytohormones was observed, with terpenoid gibberellins and brassinosteroids showing the largest differences. The metabolomic signatures induced by Trichoderma and phosphite in zucchini squash provided molecular insights into the processes underlying elicitation of plant defense due to biostimulation. Interestingly, the modulation of plant secondary metabolism by both treatments did not impair plant growth.
