Lettuce

“The average nitrate contents were the highest in lettuce (1,074 mg kg(-1))”

lettuce → has → high nitrate content

“As for the carbon metabolism, in transgenic leaves the contents of sucrose, glucose, and fructose decreased, whereas that of inulin increased up to 30 times, accompanied by the alteration of most Krebs's cycle organic acids and the rise of tartaric acid compared to nontransformed controls.”

sucrose, glucose, and fructose → decreased → in transgenic lettuce leaves

“No myosmine was detectable in other vegetables and fruits such as lettuce, spinach, cucumber, onion, banana, tangerines, and grapes.”

myosmine → is not detected in → lettuce, spinach, cucumber, onion, banana, tangerines, and grapes

“In the edible parts of the lettuce, the Se concentration was higher for selenate presence compared to selenite; however, this difference was not as obvious as it was noted in the case of the roots, where selenite application caused the high accumulation of Se.”

selenate → resulted in higher Se concentration in the edible parts of the lettuce compared to selenite → lettuce plants

“In the edible parts of the lettuce, the Se concentration was higher for selenate presence compared to selenite; however, this difference was not as obvious as it was noted in the case of the roots, where selenite application caused the high accumulation of Se.”

selenite → caused high accumulation of Se in the roots → lettuce plants
