-Breeding the oil palm (Elaeis guineensis Jacq.) for climate change requires multidisciplinary and collaborative research by nature: indeed -besides genetics and structural and functional genomics -almost all disciplines related to life sciences are involved. Research work also relies on the identification of genetic variation in the strategies of response to stress developed by the plant: this implies the exploration of resources provided by natural variation, germplasm collections, selected genitors from breeding programs together with material of interest collected from smallholders. The phenotyping of selected plant material under biotic/abiotic stress will involve new methods for high-throughput phenotyping and genomic approaches will be followed for the identification of genes underlying the variation of traits which will be used as selection targets. Also, improvements in understanding how climate change may influence chemical and physical processes in soils, how this may affect nutrient availability, and how the plant responds to changed availability of nutrients will also influence oil palm breeding programs. Molecular approaches and tools have great potential to optimize patterns of plant breeding, especially for perennial species. In recent years, there has been an exponential increase in molecular resources and methods aimed at identifying polymorphisms which control the traits of interest and exploring the mechanisms linking these polymorphisms to phenotypes. With genomic resources becoming increasingly available for the oil palm (sequencing, resequencing and chips development) the exploration of the genetic basis of complex traits such as oil yield or resistance to disease is now possible. Consequently the availability and sharing of such a large amount of data is currently reshaping most of oil palm breeding strategies.Keywords: adaptability / drought / genomics / phenotyping / plasticity / polymorphism / sex ratio Résumé -Sélection génétique du palmier à l'huile ( Elaeis guineensis Jacq. ) et changement climatique.La sélection génétique du palmier à huile pour faire face au changement climatique exige par nature une recherche pluridisciplinaire et collaborative : en effet, outre la génétique et la génomique structurelle et fonctionnelle, presque toutes les disciplines liées aux sciences de la vie sont impliquées.

“…EgmiR159a was a major factor in female flower determination in the main oil-producing crop, oil palm ( Elaeis guineesis ). High expression of EgmiR159a can increase the number of female flowers and thus increase oil production [ 37 ]. In monoecious Xanthoceras sorbifolium , 112 differentially expressed miRNAs were identified in males and females, 17 of which were directly involved in the development of flower and gametophyte, among which the miR393 and miR396 family may be involved in the development of stamen and ovule [ 38 ].…”

Androdioecy is the crucial transition state in the evolutionary direction of hermaphroditism to dioecy, however, the molecular mechanisms underlying the formation of this sex system remain unclear. While popular in China for its ornamental and cultural value, Osmanthus fragrans has an extremely rare androdioecy breeding system, meaning that there are both male and hermaphroditic plants in a population. To unravel the mechanisms underlying the formation of androdioecy, we performed small RNA sequencing studies on male and hermaphroditic O. fragrans. A total of 334 miRNAs were identified, of which 59 were differentially expressed. Functional categorization revealed that the target genes of differentially expressed miRNAs were mainly involved in the biological processes of reproductive development and the hormone signal transduction pathway. We speculated that the miRNA160, miRNA167, miRNA393 and miRNA396 families may influence the sex differentiation in O. fragrans. Overall, our study is the first exploration of miRNAs in the growth and development process of O. fragrans, and is also the first study of androdioecious plants from the miRNA sequencing perspective. The analysis of miRNAs and target genes that may be involved in the sex differentiation process lay a foundation for the ultimate discovery of the androdioecious molecular mechanism in O. fragrans.

“…Four miRNAs with targets involved in ethylene signal transduction were identified as being significantly different expression in all the continuously cultivated R. glutinosa roots. For example, miR2600a was further down-regulated in R3 and R4; its target is ACCS1, a gene encoding ACC oxidase, which is responsible for the final stage of ethylene synthesis (Sallmann et al, 2015;Somyong et al, 2016), an accumulation of ACCS1 would be expected to promote the ethylene synthesis. Furthermore, the down-regulation of miR5240b targeted the gene encoding ERTF, which underlie the positive regulation of ethylene-based signal transduction (Ohta et al, 2000;Shahin et al, 2016).…”

To cite this paper: Yang, Y., M. Li and Y. Yi, 2017. The miRNAomes in Rehmannia glutinosa roots exposed to different levels of replanting disease pressure. AbstractRoot development in the medicinal plant Rehmannia glutinosa is severely disordered by replanting disease, which occurs when it is grown in the same soils over consecutive seasons. Following the demonstration of changes to the miRNAome of the R. glutinosa plants in the second year of cultivation, a fuller experiment was organized to track the root miRNAomes over four successive plantings. Four small RNA libraries were generated from the roots of one year's planted (free of replanting disease) and 2-4 years' continuous cultivation (replanting disease) R. glutinosa plants, respectively. Sequencing of these libraries revealed the presence of 18 novel and 344 conserved miRNA families. The abundance of many of the miRNAs varied between the four libraries, consistent with the notion that replanting disease reflects the outcome differential miRNA transcription. A combined bioinformatic and degradome sequencing approach allowed the identification of 69 differentially abundant (DA) miRNA targets, leading to the recognition that particular miRNA/target modules may be important for the expression of the disease. The expression profiles of 28 key miRNAs and their targets implied that the longer years of continuous cultivation was extended, the more severe tendency of these profiles' changes would be. The indication was that the miRNAs-responsive continuous cultivation pressure reprogrammed gene expression patterns, which disordered hormone signaling, repressed core mechanisms, weakened stress tolerance and resulted in forming the disease in R. glutinosa. In conclusion, the key miRNAs involved in important roles of replanting disease and were a crucial basis for exploration in the disease forming repertoire.
