Chinese cabbage is part of a crop family that must be exposed to cold temperatures for a particular period of time in order to flower. Scientists have succeeded in comprehensively identifying the long noncoding ribonucleic acids (IncRNAs) that are expressed when Chinese cabbage is temporarily exposed to cold temperatures for four weeks. LncRNAs that are known to be involved in responding to cold in Arabidopsis thaliana do not exist in Chinese cabbage, which suggests that Chinese cabbage has its own independent mechanism for flowering.
