Growing crops closer to the consumer is one of many approaches proposed to lessen the environmental footprint associated with food production(Banerjee and Adenauer,2014).This is complicated by an increasingly urban population,the lack of available land in cities and the consequent need for rapid crop *** these constraints,to date only lettuce and related leafy greens are currently cultivated at scale in urban farms(Touliatos et al.,2016).In recent years,there are increasing interests in the urban agriculture of fruits and berries,since controlled automated vertical farming systems offer the twin advantages of optimizing land use and the ease with which they can be designed to be more environmentally friendly and sustainable than traditional ***,a considerable challenge is that commercial crop varieties were historically,and still are,bred to be high yielding under typical field and greenhouse ***,given the perishable nature of fruits and berries,a reduced distance from farm to fork renders the shelf-life trait(and its associated detrimental effects on fruit quality)less ***,the possibility to improve fruit and berry quality traits is a particularly attractive aspect of urban *** addition,the environmental benefit for these species is perhaps even greater than for other crops,since they are more often transported by air.A recent study uses multi-site CrIsPr/Cas9-mediated genome editing to restructure vine line tomato plants into compact early-yielding plants suitable for urban agriculture(Figure 1),while demonstrating that a single gene editing strategy can produce a compact stature in the related plant groundcherry(Kwon et al.,2019).

Plants produce a myriad of structurally and functionally diverse metabolites that play many different roles in plant growth and development and in plant response to continually changing environmental conditions as well as abiotic and biotic stresses. This metabolic diversity is, to a large extent, due to chemical modification of the basic skeletons of metabolites. Here, we review the major known plant metabolite modifications and summarize the progress that has been achieved and the challenges we are facing in the field. We focus on discussing both technical and functional aspects in studying the influences that various modifications have on biosynthesis, degradation, transport, and storage of metabolites, as well as their bioactivity and toxicity. Finally, we discuss some emerging insights into the evolution of metabolic pathways and metabolite functionality.
