Similar traits and functions commonly evolve in nature. Here, we explore patterns of replicated evolution across the plant kingdom discuss processes responsible for such patterns. We begin this review by defining theoretical, genetic, ecological concepts that help explain it. then focus our attention on empirical cases at phenotypic genotypic levels. find replication ecotype level is common, but evidence repeated speciation surprisingly sparse. On other hand, strategies physiological mechanisms similar biomes appears to be pervasive. conclude highlighting where future efforts can us bridge understanding different levels biological organization. Earth's landscape diverse also repeats itself. Organisms seem have followed suit.

Polyploidy is a cellular state containing more than two complete chromosome sets. It has largely been studied as discrete phenomenon in either organismal, tissue, or disease contexts. Increasingly, however, investigation of polyploidy across disciplines coalescing around common principles. For example, the recent Across Tree Life meeting considered contribution both organismal evolution over millions years and tumorigenesis much shorter timescales. Here, we build on this newfound integration with unified discussion organisms, cells, disease. We highlight how at multiple biological scales, thus eliminating outdated mindset its specialization. Additionally, discuss rules that are likely to all instances polyploidy. With increasing appreciation pervasive nature displays fascinating commonalities diverse contexts, inquiry related important topic rapidly becoming unified.

SUMMARY RNA‐Sequencing is widely used to investigate changes in gene expression at the transcription level plants. Most plant RNA‐Seq analysis pipelines base normalization approaches on assumption that total transcript levels do not vary between samples. However, this has been demonstrated. In fact, many common experimental treatments and genetic alterations affect efficiency or RNA stability, resulting unequal abundance. The addition of synthetic controls a simple correction for variation mRNA levels. adding spike‐ins appropriately challenging with complex tissue, carefully considering how they are added essential their successful use. We demonstrate external as control produces differences compared traditional methods, even two times day untreated illustrate use 3' present pipeline accounts transcriptional evaluate effect methods identifying differentially expressed genes context time response chilling stress sorghum.
