16 17 Light is a vital resource for plants, which compete for its availability particularly in dense 18 communities. Plants possess multiple photosensory receptors to detect the presence of 19 competitors and thereby adjust their growth and developmental strategies accordingly. 20 Broadly speaking plants fall into two categories depending on their response to foliar shade: 21 shade tolerant or shade avoiding. In this review we will describe the photoperception 22 mechanisms and the growth

The type of responses depends on plant density ranging from neighbor 25 detection modulating growth in anticipation of future shading to the response to canopy 26 shade where light resources are limiting. These diverse environments are sensed by various 27 photoreceptors and we will describe our current understanding of signal integration 28 triggered by distinct light cues in diverse light conditions. 29 30 31 3
