“…In addition, eIFs in same group are likely to perform similar functions. For example, groups eIF4E, eIFiso4E, and eIF4G were involved in potyvirus resistance (Duprat et al 2002;Revers and Nicaise 2014;Nicaise 2014), while eIF4B, eEF1A, eEF1B, and PABPs were found to be involved in other viral infections in many plant species (Li et al 2019;Kato et al 2010). Our results also found some new subgroups of eIFs, namely, eIF2β, eIF2α, eIF2Bβ, EF1A, and poly(A), representing new targets and mechanisms for antiviral strategies in B. juncea (Figs.…”

“…Over 40 eIF subfamilies have been identified in plant and animal species; however, only few of them have been characterized functionally (Li et al 2019). The eIFs are involved in various aspects of plant growth and development as well as disease resistance.…”

“…Moreover, eIF2B is a key regulator of the guanine nucleotide exchange factor (GEF), which is responsible for the recycling of the heterotrimeric G-protein, eIF2, to permit translation initiation (Wortham and Proud 2015). Similarly, eEF1A, eEF1B, eIF4B, and poly(A)-binding proteins (PABPs) were reported to be related with viral infections in many plants (Jackson et al 2010;Li et al 2019;Hwang et al 2013). While eIF2Bβ, eIF4E, eIF(iso)4E, eIF4G, and eIF(iso)4G have been seen to establish recessive resistance to plant viral infections (Shopan et al 2017), they have also been found to help translate viral RNA, regulate their replication, and aid in their systemic movement with the plant cells (Hwang et al 2013).…”

Eukaryotic translation initiation factors (eIFs) are essential protein complexes involved in the translation of mRNA into proteins. These initiation factors are generally used as targets in the control of plant RNA virus infections. In the present study, we identified a total 190 eIFs, clustered phylogenetically into 40 distinct subfamilies in the allopolyploid Brassica juncea. Extensive evolutionary duplications of the eIFs in B. juncea suggest their increased genetic diversity and wide adaptability. The induction of expressions in some of the eIFs after inoculation against Turnip mosaic virus (TuMV) provided candidate targets to be used in the control of viral infections. In addition, the expression profiles of eIFs under different temperatures suggested that the TuMV epidemic was temperature dependent. The eIFs expressions suggested that the systemic viral infections were more acute in plants grown between 20 °C and 28 °C. In addition, our results revealed that new subgroups of eIFs, eIF2β, eIF2α, eIF2Bβ, EF1A, and PABP could be represented as targets for antiviral strategies in B. juncea. In summary, our findings would be helpful in studying the complex mechanisms of eIF-mediated, temperature-dependent RNA virus control in B. juncea.

“…Fruits had shown increased expression of abiotic and senescence related genes in response to heat stress at 44 °C [ 185 ] and also during chilling stress [ 186 ]. Transcriptome analysis facilitated the identification of 18 eIF genes (eukaryotic elongation factor) that were expressed under salinity, osmotic and low temperature (2 °C) stress [ 49 ]. Computational analysis using EST and RNA sequence databases in mango established non-coding RNAs such as miRNAs and lncRNAs to be involved in growth and development, ripening, transcription regulation and stress responses [ 96 , 99 ] ( Table 2 ).…”

The breeding of tropical fruit trees for improving fruit traits is complicated, due to the long juvenile phase, generation cycle, parthenocarpy, polyploidy, polyembryony, heterozygosity and biotic and abiotic factors, as well as a lack of good genomic resources. Many molecular techniques have recently evolved to assist and hasten conventional breeding efforts. Molecular markers linked to fruit development and fruit quality traits such as fruit shape, size, texture, aroma, peel and pulp colour were identified in tropical fruit crops, facilitating Marker-assisted breeding (MAB). An increase in the availability of genome sequences of tropical fruits further aided in the discovery of SNP variants/Indels, QTLs and genes that can ascertain the genetic determinants of fruit characters. Through multi-omics approaches such as genomics, transcriptomics, metabolomics and proteomics, the identification and quantification of transcripts, including non-coding RNAs, involved in sugar metabolism, fruit development and ripening, shelf life, and the biotic and abiotic stress that impacts fruit quality were made possible. Utilizing genomic assisted breeding methods such as genome wide association (GWAS), genomic selection (GS) and genetic modifications using CRISPR/Cas9 and transgenics has paved the way to studying gene function and developing cultivars with desirable fruit traits by overcoming long breeding cycles. Such comprehensive multi-omics approaches related to fruit characters in tropical fruits and their applications in breeding strategies and crop improvement are reviewed, discussed and presented here.

“…Recent studies show that in mango (Mangifera indica L.), eukaryotic initiation factors (eIFs) confer abiotic stress tolerance. 11 The objective of this study was to understand the role of enzymatic and non-enzymatic antioxidant defense response mechanisms in mango fruit concerning climate change and fruit quality. Identication of genes and metabolic pathways playing a role in the molecular mechanism to heat was carried out by next-generation RNA sequencing (RNA-Seq) and transcriptome proling of ripe mango mesocarp.…”
