Provided are isolated polypeptides which are at least 80% homologous to SEQ ID NOs: 710-1153 and 9276-15726, isolated polynucleotides which are at least 80% identical to SEQ ID NOs: 1-709 and 1157-9275, nucleic acid constructs comprising same, transgenic cells expressing same, transgenic plants expressing same and method of using same for increasing yield, abiotic stress tolerance, growth rate, biomass, vigor, oil content, photosynthetic capacity, seed yield, fiber yield, fiber quality, fiber length, and/or nitrogen use efficiency of a plant.

A genetically modified plant or plant cell with reduced α1,3-fucosyltransferase and β1,2-xylosyltransferase activity compared to a wild type plant or plant cell, wherein less than 10% of the total glycan on a protein produced by the plant or plant cell is α1,3-fucosylated glycan and less than 3% of the total glycan on the protein is β1,2-xylosylated glycan is provided. In one embodiment, the plant or plant cell comprises three T-DNA insertions expressing five copies of RNAi targeting α1,3-fucosyltranserase and three copies of RNAi targeting β1,2xylosyltransferase.

Plant metabolism and alkaloid levels can be regulated by transcription factors that regulate the nicotinic alkaloid biosynthetic pathway. In one embodiment, the disclosure provides a transcription factor that negatively regulates alkaloid biosynthesis, such as nicotine biosynthesis.

Gene editing complexes are specifically directed to cannabinoid sequences, such as tetrahydrocannabinol (THC), for excision or inactivation of these sequences. The disclosure is directed to the inhibition of synthesis of THC in a cannabis plant. In doing so, THC would never become an active compound within the plant chemistry and chemotype, thereby eliminating the chance of CBD extracts being contaminated with THC.

This disclosure provides tobacco plants having a mutation in PR50 and transgenic tobacco plants containing a PR50 RNAi, and methods of making and using such plants.

MPO1 and MPO2 can be regulated for either decreasing or increasing alkaloid levels in plants, in particular in Nicotiana plants. In particular, suppressing or overexpressing one or more of MPO1 and MPO2 may be used to decrease or increase nicotine and nicotinic alkaloid levels in tobacco plants. Suppression or overexpression of one or more of MPO1 and MPO2 may be used in combination with modification of expression of other genes encoding enzymes on the nicotinic alkaloid biosynthetic pathway such as A622, NBB1, PMT, and QPT.

The present disclosure relates to recombinant prenyltransferase enzymes with increased thermostability and activity and the use of these enzymes in compositions and methods for biosynthesis involving prenylation reactions, including compositions and methods for the preparation of cannabinoids.

The present disclosure provides for unique onion plants with disease resistance and desirable bulb color and their progeny. Such plants may comprise an introgressed QTL associated with multiple disease resistance coupled with a desirable bulb color. In certain aspects, compositions, including distinct polymorphic molecular markers, and methods for producing, breeding, identifying, selecting, and the like of plants or germplasm with disease resistance and/or desirable bulb color are provided.

Methods that may be used for the manufacture of the chemical compound (R)-Reticuline and synthesis precursors thereof. Compositions useful for the synthesis (R)-Reticuline and synthesis precursors are also provided.

The present invention relates to transgenic plants with vascular xylem tissue-targeting overexpression of tissue factors involved in vascular xylem cell development.
