Precision delivery of multiscale payloads to tissue-specific targets in Plants
'Wiley', 2020Co-Authors: Cao Yunteng, Lim Eugene, Xu Menglong, Weng Jing‐ke, Marelli BenedettoAbstract:The precise deployment of functional payloads to Plant tissues is a new approach to help advance the fundamental understanding of Plant biology and accelerate Plant engineering. Here, the design of a silk‐based biomaterial is reported to fabricate a microneedle‐like device, dubbed “phytoinjector,” capable of delivering a variety of payloads ranging from small molecules to large proteins into specific loci of various Plant tissues. It is shown that phytoinjector can be used to deliver payloads into Plant vasculature to study material transport in xylem and phloem and to perform complex biochemical reactions in situ. In another application, it is demonstrated Agrobacterium‐mediated gene transfer to shoot apical meristem (SAM) and leaves at various stages of growth. Tuning of the material composition enables the fabrication of another device, dubbed “phytoSampler,” which is used to precisely Sample Plant sap. The design of Plant‐specific biomaterials to fabricate devices for drug delivery in Planta opens new avenues to enhance Plant resistance to biotic and abiotic stresses, provides new tools for diagnostics, and enables new opportunities in Plant engineering. ©2020Office of Naval Research (award no.

a method to extract morphological traits of Plant organs from 3d point clouds as a database for an architectural Plant model
Ecological Modelling, 2007Co-Authors: Tino Dornbusch, Peter Wernecke, W DiepenbrockAbstract:Abstract Combining process-based and three-dimensional (3D) structural models for specific crops to functional–structural Plant models (FSPMs) enable ecophysiologists to investigate the interaction of single Plants or Plant stands with their biotic and abiotic environment in a unique way. The present study was part of a collaborative research program on the development of a FSPM for the Sample Plant (Hordeum vulgare L.). The emphasis of this paper is put on two main aspects. First, improved generic and flexible functions are formulated for modeling the shape of leaves and stems of graminaceous Plants as organ-related triangulated surfaces, where the parameters may be directly interpreted in terms of morphological traits. The proposed functions constitute the structural model, which is amplified by topological information to a so-called architectural model. Second, we suggest a new approach to parameterize these functions based on 3D point cloud data obtained by digitization of entire Plants. Since no automated technique is available to process 3D point clouds in a way appropriate for parameterization of the architectural model, the required algorithms are developed and implemented in Matlab®. Our approach comprises the following steps. First, the measured set of points is partitioned into subsets representing each organ. Each subset is then divided further to represent organ segments. Next, the centroid of each partial point cloud representing an organ segment is computed. The sequence of these centroid points describes the organ axis. By means of the architectural model for leaves and stems, triangulated surfaces are assembled from the computed organ axis points and from user-defined initial values for the various parameters in the model (e.g. maximum leaf width). Finally, the parameters in the functions describing leaf and stem surfaces are estimated by fitting computed triangulated surfaces into the related point cloud using least squares optimization. Hence, the proposed method allows the use of 3D point clouds obtained with modern 3D digitizing techniques for the parameterization of an organ-based architectural model.

RESPON PERTUMBUHAN DAN PRODUKSI TANAMAN TERUNG UNGU (Solanum melongena L) SECARA HIDROPONIK SISTEM WICK TERHADAP PEMBERIAN NUTRISI AB MIX DAN NUTRISI EKSTRAK DAUN KELOR
'Universitas Asahan', 2020Co-Authors: Purba, Deddy Wahyudin, Patimah SitiAbstract:ABSTRACT This research was carried out at the Home page, Jalan Dusun Pajak Pulau Sejuk, Datuk Lima Puluh District, Batu Bara Regency with a flat topography and ± 15 m above sea level. The Oldeman climate type includes the E1 climate type and the Alluvial soil type. Rainfall ranges from 1,917 mm - 3,884 mm, with an average annual rainfall of 2,900 mm. The temperature ranges from 20.4 - 32.7o C and humidity is between 82% - 94%.The research was carried out from January to April 2020. This study was compiled based on a factorial randomized block design (RBD) consisting of 2 treatment factors and 3 replications. The first factor is giving AB Mix nutrition with 4 levels, namely: A0 = 0 ppm / liter of water, A1 = 750 ppm / liter of water, A2 = 1500 ppm / liter of water, A3 = 2250 ppm / liter of water. The second factor is the provision of Extra Nutrition for Moringa Leaves with 3 levels, namely: K1 = 850 ppm / liter of water, K2 = 1700 ppm / liter of water, K3 = 2550 ppm / liter of water. The results showed that the use of AB mix nutrition showed no significant effect on the parameters of Plant height, number of fruits, production per Sample Plant and eggPlant production per plot, but the number of different leaves was 6 weeks after Planting although statistically showed the best effect on A3 treatment with concentration of 2550 ppm / 1 liter. Giving extra Moringa leaves showed no significant effect on the parameters of Plant height, number of leaves, number of fruits, production per Plant, eggPlant production Samples per plot, although statistically showed the best effect on K3 treatment with a concentration of 2550 ppm / 1 liter. The interaction between the application of AB mix nutrients and the nutrition of Moringa leaves showed no significant difference in all treatments for all observations Keywords: Purple EggPlant, AB MIX Nutrition, Moringa Leaf Extract Nutritio
