From: Rapid metabolite response in leaf blade and petiole as a marker for shade avoidance syndrome
Raman spectra of various plant species under shade conditions. a Phenotype of various plant species grown in shade. Scale, 5 cm. b Carotenoid Raman peaks of leaf blade and petiole of plants in a (Baby Bok Choy: leaf blade n = 7, petiole n = 4; Bok Choy ‘Purple King’: leaf blade n = 6, petiole n = 6; Romaine Lettuce: leaf blade n = 6, petiole n = 6; Nicotiana benthamiana: leaf blade n = 3, petiole n = 3; Nicotiana tabacum: leaf blade n = 6, petiole n = 3). WL, white light; MS, moderate shade; DS, deep shade. Bars denote average ± SE. Statistical significance between WL and shade was determined by two-tailed Student’s t-test: *P < 0.05; **P < 0.01; ***P < 0.001
