Photoperiodic flowering responses are classified into three major types: long day (LD), short day (SD), and day neutral (DN). <i>Arabidopsis</i> is one of the best-characterized LD plants and flowers much earlier under LD than SD conditions. In contrast, SD conditions promote flowering of SD plants such as rice and <i>Pharbitis nil</i>. Recently, molecular genetics of <i>Arabidopsis</i> (LD) and rice (SD) have identified genes that play key roles in the photoperiodic flowering of these plants. A common role of the <i>GIGANTEA</i> (<i>GI</i>)-<i>CONSTANS</i> (<i>CO</i>)-<i>FLOWERING LOCUS T</i> (<i>FT</i>) pathway in <i>Arabidopsis</i> and rice, and a specific role of <i>EARLY HEADING DATE 1</i> (<i>EHD1</i>) in rice, but not in <i>Arabidopsis</i>, have been demonstrated. The DN response is the most poorly characterized among the three types of photoperiodic flowering responses. In this short review, we discuss how the DN flowering response is achieved in tomato based on recent progress in the analysis of <i>Arabidopsis</i> mutations in the photoperiodic flowering pathway and circadian rhythms.
