- Until recently, the majority of genomics assays have been performed on bulk tissue samples containing multiple cell types. Tissues such as the wood formation zone in trees contain a complex mix of cell types organised in three-dimensional space. Moreover, cells within the wood formation zone represent a continual developmental progression from meristematic cambial initials through to cell death. This spatiotemporal developmental gradient and cell type information are not assayed by bulk samples. New and improved sampling methods coupled to next-generation sequencing assays are enabling the generation of high spatial resolution and single-cell transcriptomics data, offering unprecedented insight into the biology of unique cell types and cell developmental programs.We overview the application of these approaches to the study of wood development, in particular, and highlight challenges associated with the analysis of such data.

- The grass family Poaceae is among the largest and most successful plant families, both ecologically and economically. It covers a wide geographic, climatic, and ecological range and contains many of the world's most important crops including wheat, barley, rice, maize, and sorghum, as well as many forage and biofuel species. Both wild and cultivated grasses are diverse in areas that regularly experience cold and freezing as well as high seasonality, harsh winters, and short growing seasons. Grasses growing in these environments have evolved an arsenal of strategies to tolerate or resist cold stress, or to escape the cold by phenological adjustments. Here, we review the current knowledge of cold adaptations in grasses synthesising across the disciplines of stress physiology, genetics, metabolomics, ecology, and evolution, in both wild and cultivated species. Specifically, we explore what is known about molecular and physiological cold stress responses, how these might have evolved and their role in shaping diversification and distribution patterns of grasses. We argue that integrating insights from multiple disciplines will further our understanding of cold adaptation.
