Abstract
Sugarcane (Saccharum spp.), a major cash crop that is an important source of sugar and bioethanol, is strongly influenced by the impacts of biotic and abiotic stresses. The intricate polyploid and aneuploid genome of sugarcane has shown various limits for conventional breeding strategies. Nonetheless, biotechnological engineering currently offers the best chance of introducing commercially significant agronomic features. In this study, an efficient Agrobacterium-mediated transformation system that uses the herbicide-resistant CP4-EPSPS gene as a selection marker was developed. Notably, all of the plants that were identified by PCR as transformants showed significant herbicide resistance. Additionally, this transformation protocol also highlighted: (i) the high yield of transgenic lines from calli (each gram of calli generated six transgenic lines); (ii) improved selection; and (iii) a higher transformation efficiency. This protocol provides a reliable tool for a routine procedure for the generation of resilient sugarcane plants.

PLANT BIOTECHNOLOGY JOURNAL 2017; 15:624-633. [PMID: 27862819 PMCID: PMC5399000 DOI: 10.1111/pbi.12661] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2016] [Revised: 11/03/2016] [Accepted: 11/05/2016] [Indexed: 05/13/2023]
Abstract
The deposition of toxic munitions compounds, such as hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX), on soils around targets in live-fire training ranges is an important source of groundwater contamination. Plants take up RDX but do not significantly degrade it. Reported here is the transformation of two perennial grass species, switchgrass (Panicum virgatum) and creeping bentgrass (Agrostis stolonifera), with the genes for degradation of RDX. These species possess a number of agronomic traits making them well equipped for the uptake and removal of RDX from root zone leachates. Transformation vectors were constructed with xplA and xplB, which confer the ability to degrade RDX, and nfsI, which encodes a nitroreductase for the detoxification of the co-contaminating explosive 2, 4, 6-trinitrotoluene (TNT). The vectors were transformed into the grass species using Agrobacterium tumefaciens infection. All transformed grass lines showing high transgene expression levels removed significantly more RDX from hydroponic solutions and retained significantly less RDX in their leaf tissues than wild-type plants. Soil columns planted with the best-performing switchgrass line were able to prevent leaching of RDX through a 0.5-m root zone. These plants represent a promising plant biotechnology to sustainably remove RDX from training range soil, thus preventing contamination of groundwater.

Abstract
The adeno-associated virus (AAV) genome can be stably integrated into the AAVS1 region of human chromosome 19 (19q13.4-qter) with the assistance of Rep68/78 protein. In the current models of AAV integration in a locus-specific manner, the foreign genes were randomly inserted into the AAVS1 region, which contains several functional genes. As random integration in this region may lead to insertion mutations and disrupt normal gene expression or critical signaling pathways of the host cells, it is necessary to find a precise insertion site in the AAVS1 region. Homologous recombination is the most accurate and versatile mechanism for such site-specific integration. To investigate site-specific integration in the AAVS1 region, a targeted vector containing two homologous arms derived from AAVS1 and a reporter gene was transfected into HeLa cells with or without Rep68/78 mRNA. The results indicated that transient expression of Rep68/78 in HeLa cells improved integration of the gene of interest at the AAVS1 locus in a site-specific manner. Compared with locus-specific integration reported in previous studies, site-specific integration may minimize the risk associated with random DNA integration in the AAVS1 region, which might be helpful for gene therapy.
