Blue light raised the stress hormone jasmonic acid by about 15% in tall soybeans and 38% in short soybeans compared to plants grown in the dark.

Scientific Claim

Blue light exposure was associated with increased jasmonic acid (JA) levels in the hypocotyls of both soybean cultivars (Henong 60: 4.36 ng/g to 5.01 ng/g; Heinong 48: 4.05 ng/g to 5.58 ng/g) compared to darkness conditions.

Original Statement

“HN60 Darkness JA 4.36 ± 0.02 b; BL 5.01 ± 0.09 a; HN48 Darkness JA 4.05 ± 0.02 b; BL 5.58 ± 0.27 a (Table 3)”

Similar Assertions

Under blue light, the stress hormone salicylic acid increased by about 56% in tall soybeans and 41% in short soybeans compared to plants grown in the dark.

89%

When soybean plants were exposed to blue light, their height dropped by about two-thirds compared to plants grown in the dark, with both tall and short varieties showing similar reductions.

85%

Blue light made the levels of a key growth hormone (GA3) drop by about 14% in tall soybeans and 20% in short soybeans when grown in the dark versus under blue light.

84%

Blue light made soybean stems thicker by increasing the water-conducting tissue area and shortening the cells, which stopped them from growing taller.

71%

Blue light made a key salicylic acid protein (NPR1) increase by 40% and a gibberellin receptor protein (GID1) decrease by 18% in soybean stems.
