Physical forces on living tissue can elicita developmental response. During embryogenesis in Arabidopsis thaliana and many Brassicaceae species, the expanding embryo abuts the embryo sac, forcing it to bend and fold. That this mechanical constraint appears to boost the seed's accumulation of lipid and protein has been validated here by combining magnetic resonance imaging with various analyses carried out at the molecular and biochemical level. The evidence is that, both in planta and in vitro, the developing Brassica napus embryo indeed responds to physical restraint by an acceleration in its maturation. While the mechanistic basis of this effect remains to be fully elucidated, the present experiments have revealed the major influence exerted by growth constraints over metabolic switching during the seed maturation process. The recognition of mechanical stimuli (referred to as mechanosensing) is a universal property of living cells, and can be critical for their health, and thus for the growth and development of the entire organism (Hamant et al., 2009; Mirabet et al., 2011; Piccolo, 2013). Animals have evolved a sophisticated mechanosensing machinery (Fratzl & Barth, 2009). Plants' ability to sense and respond to mechanical stimuli have long been of scientific interest (Darwin & Darwin, 1880), and there exist prominent examples like the insectivorous Venus flytrap (Dionaea muscipula). In recentyears, a number ofauthors have revealed some aspects of the mechanistic basis of this capacity (Chehab et al., 2009; Kurusu et al., 2013; Landrein & Hamant, 2013; Monshausen & Haswell, 2013; Basu & Haswell, 2017; Landrein
