Fig. 4From: High-quality reference genome sequences of two coconut cultivars provide insights into evolution of monocot chromosomes and differentiation of fiber content and plant heightMolecular mechanism of fiber content difference between Cn. tall and Cn. dwarf. a Fruits of Cn. tall and Cn. dwarf with a growth period of 8 months and 12 months. b The average thickness and weight of coconut fiber in the growth period of 8 months and 12 months. c Synthetic pathway of coconut lignin. The red numbers indicate the same number of these genes in Cn. tall and Cn. dwarf, while the purple numbers indicate different numbers. d, e The expression patterns of structural genes (d) and regulatory genes (e) related to lignin metabolism and synthesis in different tissues of Cn. tall and Cn. dwarf. f The phylogenetic tree analysis of the key gene family CESA for coconut cellulose synthesis. g The expression pattern of CESA gene related to cellulose synthesis in different tissues of coconut. h Epidermal cells of leaves of Cn. tall and Cn. dwarf stained by phloroglucinol/HClBack to article page
