Amolecular toolwas adapted for practical identification of theworld?s first transgenic event (Embrapa 5.1) in common bean (Phaseolus vulgaris L.). Based on the technology of RNA interference and on the transformation of plants via the Biobalistic method, a transgenic bean was created with effective resistance to Bean golden mosaic virus, its principal virus. To support the monitoring of this technology, the development of new cultivars, and the process of producing, benefiting, and distributing of seeds and grains, a molecular detection tool based on loop-mediated isothermal amplification (LAMP) was developed. This tool can facilitating diagnosis, making it fast, specific, low-cost, and easily executed. Based on the gene Ahas (GenBank M88686) of the Embrapa 5.1 event, sets of initiators were planned (forward outer primer?backward outer primer and forward inner primer?backward inner primer) that are characteristic of the LAMP method. These were evaluated for their sensitivity and specificity in detecting their target. The LAMP method allows direct visual interpretation. The Neutral Red (NR) pH indicator was adopted to facilitate molecular diagnosis in moderately well equipped environments, thus reducing the risk of contamination and the need for skilled labor. This agility in diagnosis occurs because several phases commonly used inmolecular techniques, such as polymerase chain reaction, can be excluded. The LAMPmethod, combined with a rapid DNA extraction method (modified NaOH) and the addition of NR, provides technological support for addressing issues of biosafety, traceability, and identification of the Embrapa 5.1 event in beans in the field and in industry.

The present work aimed to study the control of the biosynthesis of the antinutritional factor phytate and its associated Fe-rich protein family, ferritin, in coffee. Phytate has the ability to chelate Fe, making it unavailable to human absorption. The Coffea genome databases were queried for genes associated with phytate metabolism and ferritin genes. The genetic framework for phytate biosynthesis and its reverse pathway was identified in silico analyses and indicate that Coffea phosphatidyl inositol kinase and monophosphatase families play nonredundant roles in phytate metabolism. The transcriptional profiles of phytate biosynthesis key-genes MYO-INOSITOL(3)P1 SYNTHASE, two genes coding for PHOSPHATIDYL INOSITOL KINASE, and three FERRITIN genes were temporally evaluated by qPCR in coffee seeds from two crop locations, Adamantina-SP and Ouro-Fino-MG, the last one traditionally associated with high-quality coffee beverage grain. A targeted metabolome profile of phytic acid contents throughout three fruit maturation stages in association with the transcriptional analysis was also obtained. Taken together, our data indicate that the investigated local conditions did not cause significant alterations in phytate biosynthesis. Futhermore, the temporal transcriptional profiling revealed that candidate gene expression is regulated independently of phytate accumulation. In contrast, the expression profile of ferritin-unit genes is affected by environmental conditions and genetic background. The roles of the investigated genes are discussed concerning the quality of coffee beverage.
