6.2.1.12 | evolution | in rice, Os4CL2 belongs to the same clade as type II 4CLs in dicots, while the rest of the 4CLs (Os4CL1/3/4/5) belongs to a separate cluster, named type III, which is distinct from the lignin-associated type I 4CLs found in dicots | Oryza sativa |
6.2.1.12 | malfunction | suppression of Os4CL3 expression results in significant lignin reduction, shorter plant growth, and other morphological changes. 4CL-suppressed transgenics also display decreased panicle fertility, which may be attributed to abnormal anther development as a result of disrupted lignin synthesis, isozyme Os4Cl3 suppressed phenotype, overview | Oryza sativa |
