This disclosure concerns the use of endogenous plant RNAi machinery to preferentially or specifically reduce transgene expression. In some embodiments, the disclosure concerns specific reduction of transgene expression in seed tissues of a dicot plant.

This invention relates to gene expression regulatory sequences, specifically transcription terminator sequences. Plant transcription terminator sequences are described herein. Methods for identifying novel plant transcription terminator sequences that can terminate transcription in one orientation or in a bidirectional manner and methods of using these terminator sequences to generate transgenic plants are described herein.

Compositions and methods for controlling pests are provided. The methods involve transforming organisms with a nucleic acid sequence encoding an insecticidal protein. In particular, the nucleic acid sequences are useful for preparing plants and microorganisms that possess insecticidal activity. Thus, transformed bacteria, plants, plant cells, plant tissues and seeds are provided. Compositions are insecticidal nucleic acids and proteins of bacterial species. The sequences find use in the construction of expression vectors for subsequent transformation into organisms of interest including plants, as probes for the isolation of other homologous (or partially homologous) genes. The pesticidal proteins find use in controlling, inhibiting growth or killing Lepidopteran, Coleopteran, Dipteran, fungal, Hemipteran and nematode pest populations and for producing compositions with insecticidal activity.

A synergistic agricultural formula including at least one diacyl or diaryl urea, such as a N,N′-diformylurea, and at least one mixture of nutrients, such as a mixture of micronutrients and/or macronutrients. This synergistic agricultural formula gives those skilled in the art the ability to regulate important phenotypical parameters that lead to a variety of important agronomic and horticulture traits which improve crop yield parameters leading beyond that of its individual components.

Methods for producing in a plant a complex transgenic trait locus comprising at least two altered target sequences in a genomic region of interest are disclosed. The methods involve the use of two or more double-strand-break-inducing agents, each of which can cause a double-strand break in a target sequence in the genomic region of interest which results in an alteration in the target sequence. Also disclosed are complex transgenic trait loci in plants. A complex transgenic trait locus comprises at least two altered target sequences that are genetically linked to a polynucleotide of interest. Plants, plant cells, plant parts, and seeds comprising one or more complex transgenic trait loci are also disclosed.

A fungicidal composition containing a fungicidally effective amount of the compound of Formula I, (S)-1,1-bis(4-fluorophenyl) propan-2-yl (3-acetoxy-4-methoxypicolinoyl)-L-alaninate, and at least one fungicide selected from the group consisting of epoxiconazole, prothioconazole, azoxystrobin, pyraclostrobin, fluxapyroxad, benzovindiflupyr, and chlorothalonil, provides synergistic control of selected fungi.

A fungicidal composition containing a fungicidally effective amount of the compound of Formula I, (S)-1,1-bis(4-fluorophenyl) propan-2-yl (3-acetoxy-4-methoxypicolinoyl)-L-alaninate, and at least one fungicide selected from the group consisting of tebuconazole, prothioconazole, difenconazole, epoxiconazole, mefentrifluconazole, benzovindiflupyr, penthiopyrad, fluxapyroxad, bixafen, fluopyram, picoxystrobin, pyraclostrobin, azoxystrobin, mancozeb and chlorothalonil, provides synergistic control of selected fungi.

The invention relates to gene expression regulatory sequences, specifically introns that act as enhancers of gene expression, the promoter and terminator sequences endogenously associated with these introns. Presence of these intronic enhancer sequences in proximity to promoter sequences leads to enhancement of gene expression. Methods of finding such new intronic enhancer sequences and using them to generate transgenic plants are also described.

Disclosed herein are safened compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt or ester thereof and (b) an azole carboxylate safener or agriculturally acceptable salt or ester thereof. Also disclosed herein are methods of controlling undesirable vegetation, comprising applying to vegetation or an area adjacent the vegetation or applying in soil or water to control the emergence or growth of vegetation (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt or ester thereof and (b) an azole carboxylate safener or agriculturally acceptable salt or ester thereof.

This disclosure relates to the field of molecules having pesticidal utility against pests in Phyla Arthropoda, Mollusca, and Nematoda, processes to produce such molecules, intermediates used in such processes, pesticidal compositions containing such molecules, and processes of using such pesticidal compositions against such pests. These pesticidal compositions may be used, for example, as acaricides, insecticides, miticides, molluscicides, and nematicides. This document discloses molecules having the following formula (“Formula One”).
