Rpg1b and Rpg1r are soybean disease resistance (R) genes responsible for conferring resistance to Pseudomonas syringae strains expressing the effectors AvrB and AvrRpm1, respectively. The study of these cloned genes would be greatly facilitated by the availability of a suitable transient expression system. The commonly used Niciotiana benthamiana-based system is not suitable for studying Rpg1b ...
Using agro-infiltration technique, we have transiently expressed human Growth Hormone (hGH) in tobacco(Nicotiana tobacum), potato (Solanum tuberosum) and lettuce (Lactuca sativa) leaves. Out of three differentinoculation times used for infiltration in our study, it was seen that highest level of hGH expression wasachieved when leaves were infiltrated for 35 min. The presence o...
To accommodate fluctuating nutrient levels in the soil, plants modulate their metabolism and root development via signaling mechanisms that rapidly reprogram the plant transcriptome. In the case of nitrate, over 1,000 genes are induced or repressed within minutes of nitrate exposure. To identify cis-regulatory elements that mediate these responses, an enhancer screen was performed in transgenic...
Tomato (Solanum lycopersicum) serves as a research model for fruit development; however, while it is an important dietary source of antioxidant nutrients, the transcriptional regulation of genes that determine nutrient levels remains poorly understood. Here, the transcriptomes of fruit at seven developmental stages (7, 14, 21, 28, 35, 42 and 49 days after flowering) from two tomato cultivars (A...
To optimize the expression, extraction and purification of plant-derived tetrameric recombinant human butyrylcholinesterase (prBChE), we describe the development and use of plant viral amplicon-based gene expression system; Tobacco Mosaic Virus (TMV) RNA-based overexpression vector (TRBO) to express enzymatically active FLAG-tagged plant made recombinant butyrylcholinesterase (rBChE) in Nicotia...
Analysis of viral RNA encapsidation assay provides a rapid means of assaying which of the progeny RNA are competent for packaging into stable mature virions. Generally, a parallel analysis of total RNA and RNA obtained from purified virions is advisable for accurate interpretation of the results. In this, we describe a series of in vivo assays in which viral RNA encapsidation can be verified. T...
