Patent number: 11535858Abstract: The present invention generally relates to the field of genetic engineering and obtaining transgenic traits for agronomic applications. More specifically, the present invention relates to a specific transgenic event in agricultural crops that improves plant characteristics. Yet more specifically, the invention relates to a polynucleotide construct comprising a gene from Arabidopsis thaliana. In particular, the polynucleotide construct of the invention comprises the gene AtBBX21 which encodes a B-box protein from Arabidopsis thaliana. The transgenic event of the invention increases green and seed yield, reduces photoinhibition, improves water use efficiency, increases tuber and chlorophyll production and improves photosynthetic rates, among others. The polynucleotide construct of the invention comprises a sequence depicted as SEQ ID NO: 1. The invention also provides a transgenic plant transformed with said polynucleotide construct, wherein said plant exhibits improved characteristics.Type: GrantFiled: March 13, 2020Date of Patent: December 27, 2022Assignees: CONSEJO NACIONAL DE INVESTIGACIONES CIENTÍFICAS Y TÉCNICAS (CONICET), UNIVERSIDAD DE BUENOS AIRESInventors: Javier Francisco Botto, Carlos Daniel Crocco

Patent number: 9744236Abstract: The present invention describes Photolabile Compounds methods for use of the compounds. The Photolabile Compounds have a photoreleasable ligand, which can be biologically active, and which is photoreleased from the compound upon exposure to light. In some embodiments, the Photolabile Compounds comprise a light antenna, such as a labeling molecule or an active derivative thereof. In one embodiment, the light is visible light, which is not detrimental to the viability of biological samples, such as cells and tissues, in which the released organic molecule is bioactive and can have a therapeutic effect. In another embodiment, the photoreleasable ligand can be a labeling molecule, such as a fluorescent molecule.Type: GrantFiled: December 23, 2011Date of Patent: August 29, 2017Assignees: The Trustees of Columbia University in the City of New York, Universidad de Buenos AiresInventors: Rafael Yuste, Roberto Etchenique, Luis Baraldo
