陽光的UVB紫外線能轉化皮膚內的Provitamin D3為Vitamin D3 (維他命D)，供我們身體所用。424Please respect copyright.ＰＥＮＡＮＡE44WTGZG0b

蕃茄遇上UVB紫外光後，亦有機制將Provitamin D3轉為Vitamin D3 ，唯蕃茄當中亦有機制把Provitamin D3轉為其他物質，故最終的Vitamin D3含量並不為高。424Please respect copyright.ＰＥＮＡＮＡnpPzhYaj68

近日有科學家利用基因編輯技術(Ref1)，把7-DR2基因剔除，促使在UVB紫外線照射的情況下有更多的Provitamin D3能夠轉化成為Vitamin D3。若能將此蕃茄品種繼續加以改良及發展至市場，此蕃茄或許能成為人類吸取維他命D的主要來源之一。424Please respect copyright.ＰＥＮＡＮＡnT0vhSJDfv
