The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

The present invention relates to processes for the transformation of plant tissues with a genetic construct which comprises a transgene and a selection gene. The selection gene preferably encodes an auxin biosynthetic polypeptide, thus allowing for selection of transformed plants on media lacking plant auxins. The invention particularly relates to processes wherein the selection step is carried out under a light/dark cycle.

Aspects of the present disclosure relate to genetically modified plants comprising NODULE INCEPTION (NIN) and NIN-LIKE PROTEIN (NLP) that have been genetically altered to be responsive to auxin so that the NIN or NLP protein can induce root nodulation upon appropriate signaling.

Genetically modified lodging resistant Eragrostis plants and methods of producing lodging resistance in an Eragrostis plant, part thereof, or plant cell thereof are disclosed. Methods of improving the yield of an Eragrostis plant are also disclosed.

Plants and plant cells derived therefrom are disclosed having one or more improved or introduced desirable traits such as increased plant biomass including both increased shoot and root growth and increased seed yield. Also disclosed is a method for the production of plants with increased cold tolerance, salt tolerance, drought tolerance, and resistance to parasitic plants. Plants can be produced which have an exogenous polynucleotide molecule encoding a glycosyltransferase (UGT) and/or an exogenous polynucleotide molecule which increases transcription of an endogenous UGT.

The present disclosure provides the identification of genes involved in sucker growth in tobacco. Also provided are promoters that are preferentially active in tobacco axillary buds. Also provided are modified tobacco plants comprising reduced or no sucker growth. Also provided are methods and compositions for producing modified tobacco plants comprising reduced or no sucker growth.

The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

Aspects of the disclosure relate to systems and methods for enhancing plant performance by identifying and manipulating the expression of plant genes involved in UV-B mediated improvements to hardiness and growth. Some aspects of the disclosure relate to systems and methods for identifying plant novel genes responsive to light stimulation. Some aspects of the disclosure relate to systems and methods for identifying transgenic plants improved so as to present desired agronomic traits associated with UV-B light stimulation. Some aspects of the disclosure relate to systems and methods for modulating plant sensitivity to light for enhancing plant performance or a desired agronomic trait. Some aspects of the disclosure relate to systems and methods for generating stable transgenic plants that exhibit a desired agronomic trait.
