The regulatory region of the ribulose-1,5-bisphosphate carboxylase small subunit gene SRS4 from soybean (Glycine max) was cloned using TAIL-PCR and general PCR, and named the rbcS promoter. The promoter was fused with the GUS gene and introduced into Nicotiana tabacum via Agrobacterium-mediated leaf
The chromosomal stability of a number of somatic hybrids derived from soybean (Glycine max (L.) Merr.) and Nicotiana tabacum var. 'Xanthi' were investigated. Several of the hybrid cell lines retained more than half the complement of N. tabacum chromosomes after 7 months of culturing. A number of
Studies were conducted to identify the existence of diurnal rhythms in sucrose phosphate synthase (SPS) activity in leaves of three soybean (Glycine max L. [Merr.]) and two tobacco (Nicotiana tabacum L.) cultivars and the effect of photoperiod (15 versus 7 hours) on carbohydrate partitioning and the
The somatic hybrids of Glycine max (L)Merr.-Nicotiana glauca Grah. exhibited a preferential loss of N. glauca chromosomes. When protoplasts from such hybrid cells were 'back fused' twice to N. glauca protoplasts, a considerable increase in stability of the N. glauca chromosomes was observed. Gel
The fatty-acid composition of C. roseus and N. tabacum cell suspension cultures was unaffected by subculture on Wood and Braun, Murashige and Skoog, or Gamborg B5C media. However, placing the cultures - which were normally grown at 25° C - at 15° C reduced growth but resulted in enhanced formation
BACKGROUND
The use of light emitting diodes (LEDs) brings several key advantages over existing illumination technologies for indoor plant cultivation. Among these are that LEDs have predicted lifetimes from 50-100.000 hours without significant drops in efficiency and energy consumption is much lower
We discovered a soybean mosaic virus (SMV) variant (4278-1) that caused systemic infections in Nicotiana benthamiana plants, resulting in stem stunting and leaf shriveling. The virus had a particle morphology and incubation period similar to those of other SMV isolates but differed from them in the
Higher plant plastid DNA (ptDNA) is generally described as a double-stranded circular molecule of the size of the monomer of the plastid genome. Also, the substrates and products of ptDNA replication are generally assumed to be circular molecules. Linear or partly linear ptDNA molecules were
Seed storage oil, in the form of triacylglycerol (TAG), is degraded to provide carbon and energy during germination and early seedling growth by the fatty acid β-oxidation in the peroxisome. Although the pathways for lipid degradation have been uncovered, understanding of the exact involved enzymes
Tomato spotted wilt virus (TSWV) is a member of the family Bunyaviridae and has a wide host range including important crops such as tomato, pepper, tobacco, peanut, and onion. In areas of Georgia, soybean (Glycine max) is double cropped between two onion crops and as a rotation crop with peanuts.
A full-length cDNA, GmNRT2, encoding a putative high-affinity nitrate transporter was isolated from a Glycine max (L.) root cDNA library and sequenced. The deduced GmNRT2 protein is 530 amino acids in length and contains 12 putative membrane-spanning domains and a long, hydrophilic C-terminal
Soybean [Glycine max (L.) Merr.] embryogenic cultures were transformed by particle bombardment with the feedback-insensitive tobacco anthranilate synthase (AS) gene ASA2 driven by the CaMV 35S promoter and selected using hph as the selectable marker gene. Only one of eight regenerated lines that set
Soybean (Glycine max) is a short-day crop and the photoperiod is a crucial factor regulating its flowering time. To investigate the molecular mechanism controlling the flowering time by photoperiod in soybean, cDNA-amplified fragment length polymorphism (cDNA-AFLP) was used to identify
To assess the role of lipoxygenase (LOX; EC 1.13.11.12) in plants, we increased the expression of LOX in the tissues of Nicotiana tabacum L. cv. 'KY 14' by over-expression of the LOX2 gene from the soybean (Glycine max (L.) Merrill) embryo. The LOX2 cDNA was manipulated by replacing its
Microsomal omega-6 fatty acid desaturase (FAD2-1B) is an enzyme that regulates the polyunsaturated fatty acid content in soybeans (Glycine max). In this study, the FAD2-1B gene was determined to be highly expressed in soybean seeds using quantitative real-time PCR(qRT-PCR). To investigate the
