This invention relates to methods for increasing carbon fixation and/or increasing biomass production in a plant, comprising: introducing into a plant, plant part, and/or plant cell heterologous polynucleotides encoding (1) a succinyl CoA synthetase, (2) a 2-oxoglutarate:ferredoxin oxidoreductase, (3) a 2-oxoglutarate carboxylase, (4) an oxalosuccinate reductase, or (5) an isocitrate lyase, or (6) a succinyl CoA synthetase and a 2-oxoglutarate:ferredoxin oxidoreductase, (7) a 2-oxoglutarate carboxylase and an oxalosuccinate reductase polypeptide, and/or (8) a 2-oxoglutarate carboxylase polypeptide, an oxalosuccinate reductase polypeptide and an isocitrate lyase polypeptide to produce a stably transformed plant, plant part, and/or plant cell, wherein said heterologous polynucleotides are from a bacterial and/or an archaeal species. Additionally, transformed plants, plant parts, and/or plant cells are provided as well as products produced from the transformed plants, plant parts, and/or plant cells.

The invention provides methods for producing plants that reduce nitrous oxide (N.sub.2O) production from the soil in which they are grown. The invention involves expressing modified oleosins with artificially introduced cysteine residues in the plants. The plants optionally also express a triacylglycerol (TAG) synthesising enzyme. The invention also provides methods for reducing nitrous oxide (N.sub.2O) production from the soil in which the plants are grown. The invention also includes methods for the production of seed of the plants, and packages and use of such seed.

The present invention relates to the field of applied and environmental microorganism and agriculture. Disclosed are a thifensulfuron hydrolase gene tsmE and uses thereof. The thifensulfuron hydrolase gene tsmE has a nucleotide sequence of SEQ ID NO. 1, full length of 1194 bp, and G+C content of 51.09%, and encodes 398 amino acids with an amino acid sequence of SEQ ID NO. 2. The thifensulfuron hydrolase TsmE provided by the present invention can degrade completely 100 mg/L thifensulfuron within 1 hour into the herbicidally inactive product thiophenesulfonic acid; in addition, the TsmE also degrade completely 100 mg/L haloxyfop-R-methyl within 1 hour. Therefore, the thifensulfuron hydrolase gene tsmE is useful in construction of thifensulfuron-resistant transgenic crops and bioremediation of thifensulfuron or haloxyfop-R-methyl-contaminated environments.

Described in several example embodiments herein are NUDIX overexpressing plants and uses thereof. In some embodiments, the NUDIX overexpressing plants are used for phytoremediation.
