“…In an earlier study, suppression of lignin biosynthesis was shown to increase cellulose biosynthesis and plant growth (WEI et al, 2005). But the reduction in lignification simultaneously increased the cellulose content in wood and the xylem's vulnerability to embolism (WEI et al, 2005). This present study suggests that lignin biosynthesis in poplar contributes greatly to plant growth (HANCOCK et al, 2007).…”

Triploidy is a widespread phenomenon in cultivated and natural breeding plants and it can confer some growth advantages. Here, we analyzed genome-wide gene expression in triploid Populus euramericana (black poplar) using the Affymetrix poplar microarray to detect any possible correlation between triploid vigor and a unique gene expression profile. Among the 38,400 transcripts that were detected in triploid poplar, 1,564 and 2,015 genes were up- or downregulated, respectively, compared with the diploid. The majority of the upregulated genes in the triploid were associated with carbon and nitrogen metabolism, especially lignin and secondary metabolism. Other genes upregulated in the triploid included genes involved in sugar transport, and brassinosteroid (BR) and auxin metabolism. Downregulated genes were mostly related to the assembly and biosynthesis of ribosomes and the nucleosome macromolecular complex. The results suggested that BR and auxin levels were crucial in controlling sugar transport, photosynthesis and cell wall biosynthesis. Downregulated genes were associated with chromatin regulation in the triploid. The information from this analysis could provide an insight into the vigor of triploid poplar.

“…It has been shown by others that the total lignin-cellulose mass remains unchanged after lignin reduction due to compensatory measures which may contribute to metabolic flexibility and growth benefit to withstand the structural integrity of a plant ( Wei et al., 2005 ; Hu et al., 1999 ). In this study, all generations of four transgenic lines exhibited substantial growth in cellulose content compared to the control.…”

In the backdrop of an abundance of lignin in jute, the main focus of the present study was to conduct a quality assessment of four delignified jute lines (in which four lignin biosynthetic genes were individually downregulated) across advanced generations for industrial applications. To this end, the transgenic lines were advanced to 7 th (COMT and C4H lines) and 5 th (C3H and F5H lines) transformed generations. The results exhibit approximately 16–25% reduction in acid-insoluble lignin for the whole stem and 13–14% reduction in fiber lignin content for all four transgenic lines compared to the control. The altered lignin composition led to a 3–6% increase in the cellulose content and a small improvement in the enzymatic release of glucose. Lignin reduction led to an exposure of the underlying fibrils in transgenic lines as observed through a scanning electron microscope whereas, it was undiscernible in the control fiber. Furthermore, an analysis of the mechanical properties appears almost similar to that of the control with no morphological deformities. Jute fibers from the transgenic lines offer tremendous cost-effective implications from an economic perspective.

“…Among many others, they developed the crop canopy prototype information gathering system based on three-dimensional digital technology and achieved threedimensional reconstruction of the crop. However, the studies are mostly limited to agricultural researches, relatively few studies referred to virtual trees, and few researchers about the direction are just such as Hao Xiaoqin [7][8][9], Weiqiong [10], Shlyakhter [11], Prusinkiewicz [12], Mitsutoshi [13], etc. Besides, most researches mainly appeared in the field of pure graphics, and had little to do with the combination of tree growth.…”

The visualization of individual tree dynamic growth process provides a more intuitively visual display of individual tree growth process and effectively supports the forestry education and scientific researches. This paper presents an approach of combining the systematic analysis method and mathematical modeling techniques to realize the visual expression of the dynamic growth process of individual Mongolian pines in plantations. Quantitative analysis of morphological data and theoretical growth equation lay the foundation for establishing the dynamic growth model of individual Mongolian pines, which includes a primary branch diameter (BD) growth model, a primary branch length (BL) growth model, a height growth model, a diameter at breast height (DBH) growth model, a height of clear branches (HCB) growth model and a crown length (CL) growth model. Consolidating results of previous study--crown structure models and the development platform of VC++6.0 and OpenGL, we successfully established the virtual visualization system of individual tree growth for Mongolian pine plantation, and therefore implemented the nice integration of growth mechanism and morphological characteristics of individual Mongolian pines in plantation. The visual expression of individual tree growth provides a prerequisite for the visual forest management. In addition, it also offers a good reference for the visualization of other species.
