In this study, the optimum wavelengths of light required for carotenoid biosynthesis were determined by investigating the expression levels of carotenoid biosynthetic genes and carotenoid accumulation in sprouts of tartary buckwheat (Fagopyrum tataricum Gaertn.) exposed to white, blue, and red light-emitting diodes (LEDs). Most carotenoid biosynthetic genes(More)
A newly developed red Chinese cabbage (Brassica rapa ssp. campestris; CC) was analyzed to determine the changes in functional compounds, especially in phenolic compounds. In the red CC, cyanidin was the major anthocyanidin, with 4.11 mg·g−1 dry weight (dw), while pelargonidin and peonidin were minor components. The control CC, however, contained no(More)
Buckwheat sprouts are a popular food item in many countries. The effects of light-emitting diodes (LEDs) on sprout growth and development, changes in mRNA transcription, and accumulation of phenylpropanoid compounds were studied in tartary buckwheat 'Hokkai T8' sprouts. The highest transcript levels were observed after 2 days of LED exposure for all genes,(More)
While the effects of landscape position (LP) and management practices on soil compaction have been documented as individual factors, limited understanding exists of their interactions. Such understanding is needed to prevent site-specific compaction and to better optimize soil management practices using precision agriculture principles and technologies. The(More)
