The Arabidopsis thaliana genome encodes five DELLA proteins, whereas monocot plants, such as rice, barley, and wheat, each have a single DELLA protein. In wheat, wild-type Rht-B1a and Rht-D1a genes encode DELLA proteins and have many alleles

In silico design and molecular docking study of CDK2 inhibitors with potent cytotoxic activity against HCT116 colorectal cancer cell line. J. Genet. Eng. Biotechnol. Pub Date : 2020-09-15 Fabian Adakole Ikwu,Yusuf Isyaku,Babatunde Samuel Obadawo,Hadiza Abdulrahman Lawal,Samuel Akolade Ajibowu
Colorectal cancer is common to both sexes; third in terms of morbidity and second in terms of mortality, accounting for 10% and 9.2% of cancer cases in men and women globally. Although drugs such as bevacizumab, Camptosar, and cetuximab are being used to manage colorectal cancer, the efficacy of the drugs has been reported to vary from patient to patient. These drugs have also been reported to have

Analysis of genetic diversity and population structure in Asparagus species using SSR markers. J. Genet. Eng. Biotechnol. Pub Date : 2020-09-14 Manish Kapoor,Pooja Mawal,Vikas Sharma,Raghbir Chand Gupta
Various Asparagus species constitute the significant vegetable and medicinal genetic resource throughout the world. Asparagus species serve as important commodity of food and pharmaceutical industries in India. A diverse collection of Asparagus species from different localities of Northwest India was investigated for its genetic diversity using simple sequence repeat (SSR) markers. Polymorphic SSR

Light/heat effects on RNA editing in chloroplast NADH-plastoquinone oxidoreductase subunit 2 (ndhB) gene of Calotropis (Calotropis procera). J. Genet. Eng. Biotechnol. Pub Date : 2020-09-11 Ahmed M Ramadan
RNA editing is common in terrestrial plants, especially in mitochondria and chloroplast. In the photosynthesis process, NAD dehydrogenase plays a very important role. Subunit 2 of NADH-dehydrogenase is one of the major subunits in NAD dehydrogenase complex. Using desert plant Calotropis (Calotropis procera), this study focuses on the RNA editing activity of ndhB based on light time. NdhB (NADH-dehydrogenase

Developing a tool to shoot genes by a man-made air pressure. J. Genet. Eng. Biotechnol. Pub Date : 2020-09-11 Daisuke Tsugama,Tetsuo Takano
Biolistic systems are used to shoot exogenous DNA, RNA, protein, and other macromolecules to transfer them into cells for genetic transformation, genome editing, and drug delivery. Such systems are especially useful for plants and other organisms that are incompatible with other macromolecule delivery methods. Commercially available, conventional biolistic systems consist of a shooting device (or “gun”)

An analysis of exo-polygalacturonase bioprocess in submerged and solid-state fermentation by Pleurotus ostreatus using pomelo peel powder as carbon source. J. Genet. Eng. Biotechnol. Pub Date : 2020-09-07 Kausik Majumder,Bubai Paul,Rakhi Sundas
As there has been an increasing trend in the effective utilization of plant and crop residues for microbial transformation into a desired product, an attempt was made to compare of exo-polygalacturonase production using logistic and Luedeking-Piret kinetic model by Pleurotus ostreatus in submerged (smf) or solid-state fermentation (ssf) using pomelo peel powder, an agro-forestry residue as carbon substrate

Production of commercially important enzymes from Bacillus licheniformis KIBGE-IB3 using date fruit wastes as substrate. J. Genet. Eng. Biotechnol. Pub Date : 2020-08-31 Fatima Aslam,Asma Ansari,Afsheen Aman,Granaz Baloch,Gissed Nisar,Abdul Hameed Baloch,Haneef Ur Rehman
Pakistan is one of the top five date fruit-producing countries and produced more than 30% wastes in picking, packing, storage, and commercialization stages. The date fruit wastes are usually considered inedible for humans and only used for livestock feed. In current research, Bacillus licheniformis KIBGE-IB3 was screened for pectinase, xylanase, cellulase, and amylase production using date fruit wastes

Cloning, isolation, and characterization of novel chitinase-producing bacterial strain UM01 (Myxococcus fulvus). J. Genet. Eng. Biotechnol. Pub Date : 2020-08-31 Umar Shahbaz,Xiaobin Yu
Chitin is an important biopolymer next to cellulose, extracted in the present study. The exoskeleton of marine bycatch brachyuran crabs, namely Calappa lophos, Dromia dehaani, Dorippe facchino and also from stomatopod Squilla spp. were used to extract chitin through fermentation methods by employing two bacterial strains such as Pseudomonas aeruginosa, Serratia marcescens. The yield of chitin was 44

In silico analysis and homology modeling of strictosidine synthase involved in alkaloid biosynthesis in catharanthus roseus. J. Genet. Eng. Biotechnol. Pub Date : 2020-08-28 Archna Sahay,Anil Piprodhe,Mashitha Pise
In this study, strictosidine synthase (STR) from Catharanthus roseus that plays an important role in alkaloid biosynthesis was selected. The purpose of this work was to perform in silico analysis and to predict the three-dimensional structure of this protein that is not available. Physicochemical characterization was performed by Expasy’s Protparam server. The computed theoretical isoelectric point
