“…In Oryza sativa, Os4CL1, Os4CL3, Os4CL4, and Os4CL5 genes were all responses to lignin biosynthesis, plant growth, and other morphological changes [40]. It was also reported that lignin synthesis in rice could be reduced by C4H and 4CL using RNAi [41]. In Populus tremuloides, Pt4CL1 was also associated lignin biosynthesis when developing the xylem of woody stems [42].…”

Bamboo is one of the essential ornamental plants that is widely used as a decorative landscape element in gardens. Phyllostachys violascens cv. Viridisulcata has a unique internode color phenotype with yellow culm and green sulcus, but their structural and development differences remain unknown. In the current study, we analyzed the histological analysis of internode cross-sections through SEM and microscopy. These results revealed that the vascular bundles distributed in the culm were organized in oblique rows and multiple lines. In contrast, the vascular bundles’ distribution in the sulcus was much more random. The distribution density, maximum length, and maximum width of vascular bundles were also differentiated between the sulcus and the culm. Further, the cell wall thickness of fiber cells in the culm was more than 30% thicker than the sulcus. The FT-IR analysis identified that the culm and sulcus had similar structural properties. The total lignin content measurement revealed that lignin accumulated more in the sulcus than in the culm. Additionally, we identified the lignin biosynthesis pathway genes, Pv4CL and PvC4H, which were differentially expressed between the culm and sulcus through transcriptomic data and qPCR analyses. In conclusion, our results identified that the vascular bundles’ structure differed between the culm and sulcus, and Pv4CL and PvC4H genes might play an essential role in their development.

“…For example, repression of cinnamate-4-hydrolase (C4H) using an RNA interference approach lowered lignin content. C4H transgenic rice plants grew normally, with minimal impact observed on agronomic traits [23]. On the other hand, abnormal phenotypes due to reduced lignin content, such as dwarfing, colouration, and xylem collapse through loss of mechanical support, have also been observed.…”

Can we create “Elite Rice”—a multifunctional crop for food, feed, and bioenergy production?

Because arable land is limited, land use for food and bioenergy production remains a controversial issue. If food crops can generate high yields and the biomass can also be used effectively for both animal feed and bioenergy production feedstock, conflicts over land use can be reduced. Rice is an important crop; as a worldwide staple food with abundant residuals (polysaccharide-rich straw) after grain collection, this crop plant is attractive as a renewable raw material for bioenergy and feed production. Here, we address current issues and discuss promising methods for improving rice plant characteristics suitable for food, feed, and bioenergy production. Advanced genetic engineering techniques can be used to precisely manipulate the mechanisms regulating grain production, cellulose and lignin content, and stress tolerance. In addition, genetic modification of the mechanisms controlling glycoside hydrolase expression can enhance biomass saccharification for bioenergy production and improved animal digestibility. We also address the issue of nutrient recycling associated with rice straw utilisation for biofuel production.
