To provide a base sequence for protein expression that can increase the yield of protein such as diastatic enzyme by further activating a promoter of a particular gene. A base sequence 1 for protein expression includes: a gene 3 encoding protein 2; a promoter 4 of the gene 3, the promoter being linked upstream of the gene 3; and a cis element 5 whose activity is improved by an artificial transcription factor 6, the cis element being linked further upstream of the promoter 4. The cis element 5 is represented by SEQ ID NO: 1.

Disclosed are use of a polynucleotide, protein, and biological material in the regulation and control of plant tuber development, and related products and production methods thereof. The tuber plant or part thereof, comprising a sequence encoding a polypeptide comprising a sequence having at least 92% sequence identity to SEQ ID NO: 2, wherein the polypeptide is inhibited-expressed, loss-function, or overexpressed, and the development of plant tuber is changed. The polynucleotide is an identity gene of a tuber, and can control whether a tuber is formed, the formation time, the tuber size etc. by regulating and controlling a protein function, an expression quantity etc.

The present disclosure relates, according to some embodiments, to compositions, organisms, systems, and methods for expressing a gene product in a plant (e.g., a monocot) using a promoter operable in one or more plant tissues and/or cells. In some embodiments, an artificial nucleic acid may comprise an expression control sequence having the sequence selected from the sequence of nucleotides 1-4710 of SEQ ID NO: 1 and the sequence of nucleotides 1137-4710 of SEQ ID NO: 1, wherein the expression control sequence has stem-regulated promoter activity in at least one monocot (e.g., at least two monocots).

Genetically modified tobacco plants are provided having altered hexose accumulation. Methods are provided for producing ethanol from fermentation of tobacco biomass derived from the tobacco plants having altered hexose accumulation. The altered hexose accumulation can be an increase in total hexose content or an increase in hexose content in the phloem or the roots/shoots as compared to non-genetically modified tobacco plants. Expression vectors are provided for tobacco plant transformation having a gene encoding a sucrose invertase inhibitor operably linked to a promoter, such that expression of the inhibitor in the plant can increase and/or alter hexose accumulation in the plant. The genetically modified tobacco plants having altered hexose accumulation can further contain a transgenic construct to confer resistance to a glyphosate herbicide or a phosphinothricin (PPT) herbicide.

The present invention relates to genetically modified plants comprising a heterologous nucleic acid construct comprising a promoter sequence operably linked to a coding sequence encoding a gene product. The invention further relates to methods for producing such plants.
