The present disclosure relates to a fertility gene and the use thereof, and relates to the biotechnology field, particularly to a method of plant hybrid breeding including creation of a sterile line and preparation of hybrid seeds, more particularly to a fertility gene FL2, a mutant thereof and use thereof in hybrid breeding.

The present disclosure relates to an expression vector for restoring male sterility in a plant. The expression vector comprises a regulatory region sequence operably linked to a heterologous nucleotide sequence.

This disclosure concerns compositions and methods for promoting transcription of a nucleotide sequence in a plant or plant cell, employing a promoter from a Panicum virgatum (Pavir.J00490) egg cell gene. Some embodiments relate to a promoter from a Panicum virgatum (Pavir.J00490) egg cell gene that functions in plants to promote transcription of operably linked nucleotide sequences. Other embodiments relate to a 3 UTR from a Panicum virgatum (Pavir.J00490) egg cell gene that functions in plants to promote transcription of operably linked nucleotide sequences.

The invention provides recombinant DNA molecules and constructs, as well as their nucleotide sequences, useful for modulating gene expression in plants. The invention also provides transgenic plants, plant cells, plant parts, and seeds comprising the recombinant DNA molecules operably linked to heterologous transcribable DNA molecules, as are methods of their use.

This disclosure provides methods and compositions for increasing genome editing and site-directed integration events utilizing guided endonucleases and floral cell-preferred or floral tissue-preferred promoters.

Compositions and methods comprising polynucleotides and polypeptides having 4-hydroxyphenylpyruvate dioxygenase (HPPD) activity and having insensitivity to an HPPD inhibitor are provided. Further provided are nucleic acid constructs, plants, plant cells, explants, seeds and grain having the HPPD sequences. Various methods of employing the HPPD sequences are provided. Such methods include, for example, methods for producing an HPPD inhibitor tolerant plant, plant cell, explant or seed and methods of controlling weeds in a field containing a crop employing the plants and/or seeds disclosed herein. Methods are also provided to identify additional HPPD variants. Further provided are various methods and compositions that allow the various HPPD polypeptides and variant and fragments thereof to be expressed in a chloroplast or transported to a chloroplast.
