“…Fruit trees such as apple ( M. domestica ), peach ( P. persica ), citrus ( Citrus spp.) and grapevine ( V. vinifera ) are among the most economically important fruit crops in the world (Hanke & Flachowsky ). Understanding how miRNAs function in the development of woody fruit species, as well as their roles in mediating stress responses, could provide new insights for improving fruit trees and grapevines.…”

MicroRNAs in fruit trees: discovery, diversity and future research directions

Since the first description of microRNAs (miRNAs) 20 years ago, the number of miRNAs identified in different eukaryotic organisms has exploded, largely due to the recent advances in DNA sequencing technologies. Functional studies, mostly from model species, have revealed that miRNAs are major post-transcriptional regulators of gene expression in eukaryotes. In plants, they are implicated in fundamental biological processes, from plant development and morphogenesis, to regulation of plant pathogen and abiotic stress responses. Although a substantial number of miRNAs have been identified in fruit trees to date, their functions remain largely uncharacterised. The present review aims to summarise the progress made in miRNA research in fruit trees, focusing specifically on the economically important species Prunus persica, Malus domestica, Citrus spp, and Vitis vinifera. We also discuss future miRNA research prospects in these plants and highlight potential applications of miRNAs in the on-going improvement of fruit trees.

“…Shortening the juvenile phase in apple is possible by overexpression of flowering genes or by silencing of repressor genes that suppress flowering genes during the juvenile phase. This has been demonstrated with stably transformed plants ( Kotoda et al, 2003 ; Flachowsky et al, 2007 , 2012 ; Trankner et al, 2010 ; Tanaka et al, 2014 ), but also with transient expression of gene constructs using a virus vector system ( Hanke and Flachowsky, 2010 ; Yamagishi et al, 2016 ).…”

“…Established protocols are time-consuming and the efficiency of transformation is comparatively low ( Hanke et al, 2020 ). Several publications summarized the efforts and achievements of genetic engineering in apple ( Bulley et al, 2007 ; Gessler and Patocchi, 2007 ; Bhatti and Jha, 2010 ; Hanke and Flachowsky, 2010 ; Rai and Shekhawat, 2014 ). A lot of work, energy, and effort has gone into developing selection methods as an alternative to nptII ( Szankowski et al, 2003 ; Degenhardt et al, 2006 ) and establishing strategies for developing marker gene-free plants ( Krens et al, 2004 ; Herzog et al, 2012 ).…”

Recent Developments and Strategies for the Application of Agrobacterium-Mediated Transformation of Apple Malus × domestica Borkh

Genetic transformation has become an important tool in plant genome research over the last three decades. This applies not only to model plants such as Arabidopsis thaliana but also increasingly to cultivated plants, where the establishment of transformation methods could still pose many problems. One of such plants is the apple (Malus spp.), the most important fruit of the temperate climate zone. Although the genetic transformation of apple using Agrobacterium tumefaciens has been possible since 1989, only a few research groups worldwide have successfully applied this technology, and efficiency remains poor. Nevertheless, there have been some developments, especially in recent years, which allowed for the expansion of the toolbox of breeders and breeding researchers. This review article attempts to summarize recent developments in the Agrobacterium-mediated transformation strategies of apple. In addition to the use of different tissues and media for transformation, agroinfiltration, as well as pre-transformation with a Baby boom transcription factor are notable successes that have improved transformation efficiency in apple. Further, we highlight targeted gene silencing applications. Besides the classical strategies of RNAi-based silencing by stable transformation with hairpin gene constructs, optimized protocols for virus-induced gene silencing (VIGS) and artificial micro RNAs (amiRNAs) have emerged as powerful technologies for silencing genes of interest. Success has also been achieved in establishing methods for targeted genome editing (GE). For example, it was recently possible for the first time to generate a homohistont GE line into which a biallelic mutation was specifically inserted in a target gene. In addition to these methods, which are primarily aimed at increasing transformation efficiency, improving the precision of genetic modification and reducing the time required, methods are also discussed in which genetically modified plants are used for breeding purposes. In particular, the current state of the rapid crop cycle breeding system and its applications will be presented.

“…The cultivation of fruit crops has a significant impact on the overall well-being of humans and the state of the nation. Fruit crop production can be viewed as an open and complex system in which factors including the sowing or planting method, environmental conditions, soil type, crop management, and their interactions affect the growth, development, and future yield [1].…”

New Advances in Postharvest Technology

Nutritional security can be achieved only with the proper intake of fruits and vegetables. However, on an average 30% of the fruit produce are lost between harvest and consumption due to post-harvest spoilage. About 30–40% of total fruits production is lost after harvest. Main causes of postharvest loss include lack of temperature management, rough handling, poor packaging material, and lack of education about the need to maintain quality. There are many ways in which the post-harvest spoilage is managed. Use of chemicals in post-harvest management has direct effect on the consumers and there is a need for alternative strategies. Use of microbial biological control agents have been successfully adopted for soil borne diseases. Registration and biosafety issues make it difficult to use them against post-harvest diseases. Use of volatile organic compounds (VOCs) from bioagents for the post-harvest management provides an opportunity to explore the use of bioagents without having contact with fruits. Many classes of chemicals are produced as volatiles by microbial agents. This chapter describes the potential of VOCs in managing post-harvest diseases, their characterization and identification, biosynthesis, volatiles reported from bacterial, fungal and yeast bioagents, success stories of their use as potential bioagents.
