Isolated polynucleotides and polypeptides, and recombinant DNA constructs useful for conferring improved nitrogen use efficiency; compositions (such as plants or seeds) comprising these recombinant DNA constructs; and methods utilizing these recombinant DNA constructs are disclosed. The recombinant DNA constructs comprise a polynucleotide operably linked to a promoter that is functional in a plant, wherein said polynucleotides encode abiotic stress tolerance polypeptides.

This disclosure provides recombinant DNA constructs and transgenic plants having enhanced traits such as increased yield, increased nitrogen use efficiency, and enhanced drought tolerance or water use efficiency. Transgenic plants may include field crops as well as plant propagules, plant parts and progeny of such transgenic plants. Methods of making and using such transgenic plants are also provided. This disclosure also provides methods of producing seed from such transgenic plants, growing such seed, and selecting progeny plants with enhanced traits. Also disclosed are transgenic plants with altered phenotypes which are useful for screening and selecting transgenic events for the desired enhanced trait.

The present disclosure belongs to the technical field of plant genetic engineering, and in particular relates to use of an ALR1 gene or an ALR1 protein of an aluminum ion receptor in regulating plant aluminum resistance. In the present disclosure, a primers includes an upstream primer with a nucleotide sequence shown in SEQ ID NO: 1 and a downstream primer with a nucleotide sequence shown in SEQ ID NO: 2. The primer is capable of improving the plant aluminum resistance and promoting growth of a plant root system, thereby promoting absorption of nutrients and water by the plant, which is of great significance for improving a yield of crops.

The present invention relates to isolated nucleic acid molecules and their corresponding encoded polypeptides able confer the trait of improved plant size, vegetative growth, growth rate, seedling vigor and/or biomass in plants challenged with saline and/or oxidative stress conditions. The present invention further relates to the use of these nucleic acid molecules and polypeptides in making transgenic plants, plant cells, plant materials or seeds of a plant having plant size, vegetative growth, growth rate, seedling vigor and/or biomass that are improved in saline and/or oxidative stress conditions with respect to wild-type plants grown under similar conditions.

Methods and materials for increasing abiotic stress tolerance in plants are disclosed. For example, nucleic acids encoding abiotic stress tolerance-increasing polypeptides are disclosed as well as methods for using such nucleic acids to transform plant cells. Also disclosed are plants having increased tolerance to abiotic stress and methods of increasing plant yield under abiotic stress conditions.

A new and distinct lettuce variety NUN 06529 LTL is disclosed, as well as seeds and plants and heads or leaves thereof. NUN 06529 LTL is mini romaine lettuce variety, comprising resistance to Downy Mildew (Bremia lactucae) isolates B1:16-37EU and Lettuce Mosaic Virus (LMV) Pathotype II.

The present invention relates to excision of explant material comprising meristematic tissue from seeds, and storage of such material prior to subsequent use in plant tissue culture and genetic transformation. Methods for tissue preparation, storage, and transformation are disclosed, as is transformable meristem tissue produced by such methods, and apparati for tissue preparation.
