Carotenoids identified in Verticillium agaricinum under near-UV were beta-, zeta-, and gamma-carotenes, neurosporene, torulene, neurosporaxanthin and one of its esters. Evidence supports the proposal that gamma-carotene, and not torulene, is the immediate precursor of neurosporaxanthin. It is also suggested that phytochrome may be involved in the high irradiance reactions (HIR) causing carotenoid synthesis in this fungus although there is no knowledge of how this is effected. Spores grown under near-UV conditions varied in size and shape from those grown in the dark. A new pigment (390, 420 nm) is also proposed as the photoreceptor for carotenogenesis in V. agaricinum.
在近紫外光下在黄萎病菌中鉴定出的类胡萝卜素为β-、ζ-和γ-胡萝卜素、八氢番茄红素、链孢红素、神经孢菌黄素及其一种酯。有证据支持γ-胡萝卜素而非链孢红素是神经孢菌黄素的直接前体这一观点。还表明，尽管尚不清楚其作用方式，但光敏色素可能参与了导致该真菌类胡萝卜素合成的高辐照反应（HIR）。在近紫外光条件下生长的孢子在大小和形状上与在黑暗中生长的孢子不同。还提出了一种新的色素（390、420纳米）作为黄萎病菌类胡萝卜素生成的光感受器。
