摘要:
The present invention relates to a DNA fragment specific to a cytoplasmic male sterile pepper comprising a polynucleotide of SEQ ID NO: 1, a candidate polynucleotide (named orf456) associated with cytoplasmic male sterile pepper consisting of a 223rd to 678th nucleic acid of SEQ ID NO:1, and a polynucleotide of SEQ ID NO: 2. The DNA fragment specific to cytoplasmic male sterile pepper comprising a polynucleotide of SEQ ID NOs: 1 or 2 can be used for identifying cytoplasmic type between male sterile and male fertile pepper by the PCR method. In addition, hybrid pepper breeders/seed companies could detect impurities of the maintainer line within the CMS line, and by ensuring purity of the CMS line, a major source of contamination of the hybrid seeds is removed leading to obvious benefits for the seed industry and farmers.

摘要:
The present invention provides transgenic higher plants and transgenic plant cells thereof which have been transformed with a plant translationally controlled tumor protein (TCTP) gene to improve growth rate in a growth stage-dependent manner, especially in the earlier vegetative growth stage from seedlings to young plants. Also, the invention provides methods for engineering higher plants so that they can be more efficiently transformed with other transforming vector constructs. Further, provided are TCTP expression vectors which contain an uninterrupted coding region for the TCTP protein used to generate transgenic plants and cells thereof.
摘要:
The present invention provides a nucleic acid molecule isolated from the 5′ untranscribed region of a translationally controlled tumor protein (TCTP) gene from Arabidopsis. The nucleic acid molecule, referred to as TCTP promoter in the present invention, directs the high-level expression of a reporter gene that is properly placed under its control. The TCTP promoter initiates and regulates the gene expression to a level that is comparable to those by the currently available promoters in plant genetic engineering. A minimum of 300-bp region is enough for fill regulatory activity. The TCTP promoter is functional in all plant tissues tested with the highest activity in the meristem tissue of root tip. The present invention can be utilized to express useful genes to a high level in agronomically important plants.
摘要:
The present invention provides an efficient genetic transformation system for the zoysiagrass plant (Zoysia japonica Steud.). Also provided are optimized media compositions and culture conditions for the zoysiagrass transformation. The reliable transformation system for zoysiagrass was developed by optimizing several factors that significantly affect calli growth and plant regeneration. Callus type and co-cultivation period absolutely influenced the transformation efficiency. Concentrations of 2,4-D, CaCl2 and acetosyringone were also critical factors. The best result was achieved when type 3 calli were co-cultivated on a 2,4-D-free co-cultivation medium for 6 days. Removal of calcium and addition of 50 mg/liter acetosyringone during co-cultivation drastically enhanced the efficiency. The invention also provides a bialaphos-resistant zoysiagrass plant, which can be used in golf courses and athletic fields to save the maintenance cost.

摘要:
Fully differentiated higher plants may be regenerated from undifferentiated plant tissues, such as callus, derived from mature seeds, immature embryos, stems, roots, or leaves. The present invention provides a plant regeneration method from mature seed-derived calli. The regeneration procedure may include the induction of calli on the MS media containing 2 mg/L 2,4-dichlorophenoxyacetic acid and 0.2 mg/L 6-benzylaminopurine, 4 mg/L thiamine-HCl, and 100 mg/L &agr;-ketoglutaric acid. The plant regeneration efficiency is the highest when calli are grown on the MS media supplemented with 3% maltose and 1 mg/L 6-benzylaminopurine or 1 mg/L thidiazuron (TDZ). The invention can be utilized to introduce a gene or genes of agronomically important values into the zoysiagrass or possibly closely related turfgrass species.
