Two copies of a Polycomb target gene in the same cell can be maintained in independently heritable expression states, demonstrating that long-term memory of gene expression is stored locally.
Comprehensive analyses of host genetics, root-associated microbiomes, and plant phenotypes under two nitrogen treatments reveals host genetic control of microbe abundance which, in turn, affects plant performance.
After domestication, the cultivation range expansion of crops was not solely dictated by human activity but instead constrained by climatic factors, which in turn resulted in distinct phenotypic characteristics of locally adaptive landraces.

The expression of Arabidopsis NLR immune response genes is modulated by premature transcription termination, and this has implications for understanding NLR regulation and evolutionary dynamics.

Natural variation for an adaptively important life history trait is largely due to variation at a single, major-effect locus with multiple alleles, demonstrating that not all complex traits are massively polygenic.

The sense of smell of female hawkmoths has evolved to find the intense odor of floral nectar sources as well as inconspicuous scents of oviposition sites within a complex olfactory landscape.

The mosses and angiosperms have independently evolved mechanisms that use the same hormones-auxin, cytokinin and strigolactone-to regulate lateral shoot branching.
