In this paper, we present a novel approach for assessing and interacting with surface tracking algorithms targeting video manipulation in postproduction. As tracking inaccuracies are unavoidable,we enable the user to provide small hints to the algorithms instead of correcting erroneous results afterwards. Based on 2D mesh warp-based optical flow estimation, we visualize results and provide tools for user feedback in a consistent reference system, texture space. In this space, accurate tracking results are reflected by static appearance, and errors can easily be spotted as apparent change. A variety of established tools can be utilized to visualize and assess the change between frames. User interaction to improve tracking results becomes more intuitive in texture space, as it can focus on a small region rather than a moving *** show how established tools can be implemented for interaction in texture space to provide a more intuitive interface allowing more effective and accurate user feedback.

Genome editing is a valuable tool to target specific DNA sequences for mutagenesis in the genomes of microbes, plants, and animals. Although different genome editing technologies are available, the clustered regularly interspaced short palindromic repeats/Cas9 （CRIsPR/ Cas9） system, which utilizes engineered endonucleases to generate a double-stranded DNA break （DsB） in the target DNA region and subsequently stimulates site-specific mutagenesis through DNA repair machineries, is emerging as a powerful genome editing tool for elucidating mecha- nisms of protection from plant viruses, plant disease resistance, and gene functions in basic and applied research. In this review, we provide an overview of recent advances in the CRIsPR system associated genome editing in plants by focusing on application of this technology in model plants, crop plants, fruit plants, woody plants and grasses and discuss how genome editing associated with the CRIsPR system can provide insights into genome modifications and functional genomics in plants.

Transcriptional regulatory mechanisms that control transcriptional regulators, target genes, and their interactions provide new insights into general development processes throughout the life cycle of the plant. Although different molecular mechanisms that regulate plant growth and development have been identified, detailed transcriptional mechanisms that control gene expression, modulate developmental programmes, and determine cell fates in plant development are not fully understood. To increase our understanding on transcriptional mechanisms regulating diverse processes in plant development, we have reviewed the regulation of transcription during the process of development including transcriptional mechanisms regulating root, stem, leaf, flower, seed, embryo, endosperm, ovule, fruit, and chloroplast development. We have summarized the interaction, expression, transport, signaling events of transcriptional regulators and their targets in a number of model plants and highlighted the involvement of hormones and microRNAs in plant development. Understanding the precise transcriptional mechanisms regulating gene expression in plant development will be valuable for plant molecular breeding.

Transgenic trees as a new source for biofuel have brought a great interest in tree biotechnology. Genetically modifying forest trees for ethanol production have advantages in technical challenges, costs, environmental concerns, and financial problems over some of crops. Genetic engineering of forest trees can be used to reduce the level of lignin, to produce the fast-growing trees, to develop trees with higher cellulose, and to allow the trees to be grown more widely. Trees can establish themselves in the field with less care of farmers, compared to most of crops. Transgenic crops as a new source for biofuel have been recently reviewed in several reviews. Here, we overview transgenic woody plants as a new source for biofuel including genetically modified woody plants and environment; main focus of woody plants genetic modifications; solar to chemical energy transfer; cellulose biosynthesis; lignin biosynthesis; and cellulosic ethanol as biofuel.
