biostudies-literatureUnknown11Liu XL<i>Yellow</i> genes are thought to be involved in the melanin biosynthetic pathway and play a crucial role in pigmentation reactions in insects. However, little research has been done on <i>yellow</i> genes in lepidopteran pests. To clarify the function of one of the <i>yellow</i> genes (<i>yellow-y</i>) in <i>Spodoptera litura</i>, we cloned the full-length of <i>yellow-y</i>, and investigated its spatial and temporal expression profiles by quantitative real-time PCR (qPCR). It revealed that <i>yellow-y</i> was highly expressed in larva of fourth, fifth, and sixth instars, as well as in epidermis (Ep), fat bodies (FB), Malpighian tubes (MT), and midguts (MG) of the larvae; whereas it was expressed in very low levels in different tissues of adults, and was almost undetected in pupa.
