Proteomes and Histone Crotonylation Analysis Reveals the Importance of Crotonylation Low Temperature in Chrysanthemum


ABSTRACT: Chrysanthemum is a garden plant with good economic benefit and high ornamental value. Chrysanthemum in the key period of flowering in autumn and winter, vulnerable to cold damage, affecting the normal growth of the chrysanthemum plant and even death. little is known regarding the study of histone crotonylation in plant cold response. In this study, we first obtained reference chrysanthemum transcriptome data via RNA sequencing. Next, we quantitatively investigated the chrysanthemum proteome, crotonylation, and the association between them in chrysanthemum following low temperature. In total, 365669 unigenes, 6693 proteins and 2017 crotonylation sites were quantified under low temperature stress. There were 24631 up-regulated and 22648 down-regulated unigenes (absolute log2-fold change > 1 and P value<0.05), 393 up-regulated and 500 down-regulated proteins using a 1.2-fold threshold (P<0.05). The lysine crotonylation mainly influenced in photosynthesis, ribosome, antioxidant enzyme and ROS system. In the process of low temperature, 61 lysine crotonylation sites in 89 proteins were up-regulated and 87 lysine crotonylation sites in 72 proteins are down-regulated (1.2-fold threshold, P<0.05).

<h4>Background</h4>Low-temperature severely affects the growth and development of chrysanthemum which is one kind of ornamental plant well-known and widely used in the world. Lysine crotonylation is a recently identified post-translational modification (PTM) with multiple cellular functions. However, lysine crotonylation under low-temperature stress has not been studied.<h4>Results</h4>Proteome-wide and lysine crotonylation of chrysanthemum at low-temperature was analyzed using TMT (Tandem Mass  ...[more]
