Grape Transcriptomics and Viticulture

A major goal of viticulture is to exert control over ripening and produce fruit of reproducible yield and quality. This implies developing effective viticultural practices, breeding cultivars with improved characteristics, and requires considering the numerous variables that can influence development and ripening, like cultivar-specific traits, regional climate, and stresses. Molecular tools aid these efforts. Among them, transcriptome measurements that capture expression across the genome allow monitoring which genomic features are transcribed given the aforementioned variables. The technologies used to study the transcriptome have rapidly improved and become less expensive since the early 2000s, increasing the feasibility of developing molecular marker-driven practices. This chapter briefly reviews the history and state of transcriptomic technologies since they have been applied to grapevine, reviews the seminal publications that have used these tools, and proposes a direction for this field in the future

The non-coding road towards cardiac regeneration

Our understanding of cardiovascular disease has evolved rapidly, leading to a number of treatments that have improved patient quality of life and mortality rates. However, there is still no cure for heart failure. This has led to the pursuit of cardiac regeneration to prevent, and ultimately cure, this debilitating condition. To this end, several approaches have been proposed, including activation of cardiomyocyte proliferation, activation of endogenous or exogenous stem/progenitor cells, delivery of de novo cardiomyocytes, and in situ direct reprogramming of cardiac fibroblasts. While these different methodologies are currently being intensely investigated, there are still a number of caveats limiting their application in the clinic. Given the emerging regulatory potential of non-coding RNAs for controlling diverse cellular processes, these molecules may offer potential solutions in this pursuit of cardiac regeneration. In this concise review, we discuss the potential role of non-coding RNAs in a variety of different cardiac regenerative approaches
