Glutathione Dynamics in Arabidopsis Seed Development and Germination
Seed desiccation and germination have great potential for oxidative stress. Glutathione, one of the most abundant antioxidants in plant cells, is a crucial to the plant's defense mechanisms. To better understand glutathione's responses during these two stages, we examined its dynamics in wildtype …

Transcript Profiling of Soybean Seed Development From Fertilization to Maturity
… significantly during various stages of soybean seed development, from just a few days after fertilization to the stages of seed fill, maturation, and desiccation. Gene expression over five stages from four to twenty-four days after fertilization in whole seeds was measured using microarrays …

Some aspects of the seed development and seedling growth of rimu, Dacrydium cupressinum, Lamb
The morphological stages of seed development in rimu were analysed by studying microtome sections and by dissections of ovules under a stereomicroscope. Development takes 18 months from the time ovules become visible and losses occur throughout this time. Many empty seed are produced and this has …

Identification and characterization of a matrix metalloproteinase (Pta1-MMP) expressed during Loblolly pine (Pinus taeda) seed development and germination
… (ECM) modifications occur during plant growth, development, and in response to environmental stimuli. Key modulators of ECM modification in vertebrates, the extracellular matrix metalloproteinases (MMPs), have also been described in a few plants. Here, we report the identification of Loblolly …

A Machine Learning Approach to Predict Gene Regulatory Networks in Seed Development in Arabidopsis Using Time Series Gene Expression Data
… learning approach to predict GRNs that occur in developmental stage-specific networks and to show how it improves our understanding of the GRN in seed development. I developed a Beacon GRN inference tool to predict a GRN in seed development in Arabidopsis based on a support vector machine (SVM) …

Role of virus genes in seed and aphid transmission and development of a virus-induced gene silencing system to study seed development in soybean
… and Tobacco streak virus (TSV) are two important seed transmitted virus that infect soybean. SMV is a member of the family Potyviridae genus Potyvirus, and is transmitted by seed and aphids in soybean. The symptoms of SMV infection on soybean typically include mosaic and curling of leaves, reduced …

Green soybeans: Physical and rheological properties, optimization of harvest time, and mechanical harvesting and shelling
… soybeans were measured at different stages of seed development. These properties included texture, color, size, and seed strength. Mathematical models were developed relating each property to seed development. The models were then combined to develop an objective function to predict the …

"The Regulation of Pheophorbide a Oxygenase (Pao) in the ""Green Seed"" Problem in Canola and During Leaf Senescence"
Brassica napus, canola, is an important oil seed crop grown extensively in North America and northern Europe with annual yields exceeding seven million metric tons. Under normal field conditions, canola seeds produce chloroplasts during early seed development and then catabolize the photosynthetic …

BIOCHEMICAL AND MOLECULAR CHARACTERIZATION OF RAFFINOSE FAMILY OLIGOSACCHARIDE (RFO) BIOSYNTHESIS IN LENTIL (Lens culinaris Medik.)
… molecular mechanism of RFO deposition in lentil seeds. The main objective of this study was to isolate and characterize RFO biosynthetic genes galactinol synthase (GS or GolS; EC 2.4.1.123), raffinose synthase (RS; EC 2.4.1.82) and stachyose synthase (STS; EC 2.4.1.67). The expression of RFO …

Isolation and Characterization of D-Myo-Inositol-3-Phosphate Synthase Gene Family Members in Soybean
… isolated via PCR using total RNA from developing seeds. Southern blot analysis and examination of MIPS-homologous soybean EST sequences suggested that GmMIPS1 is part of a multigene family of at least four similar members. The sequences of promoter and genomic regions of GmMIPS1 and GmMIPS2 …

The effect of water stress and storage conditions on seed quality of chickpea genotypes characterized by differences in seed size and coat colour
… in agricultural ecosystems. However, its seed quality and hence reproduction is constrained by water stress, seed size and storage conditions. This study was carried out at the University of KwaZulu- Natal (UKZN), Pietermaritzburg Campus. It was conducted to evaluate the performance of …

Cloning and characterisation of LEA1-EM genes in the resurrection plant, Xerophyta humilis
… desiccation and germination phase of angiosperm seed development. The group I LEA genes are characterised by the presence of one or more tandemly repeated 20-amino acid motifs that are particularly rich in Gly residues.

Genome and Transcriptome Based Characterization of Low Phytate Soybean and Rsv3-Type Resistance to Soybean Mosaic Virus
Soybean is a dominant oilseed cultivated worldwide for its use in multiple sectors such as food and feed industries, animal husbandry, cosmetics and pharmaceutical sectors, and more recently, in production of biodiesel. Increasing demand of soybean, changing environmental conditions, and evolution …

Raffinose family oligosaccharides (RFO) biosynthesis in chickpea (Cicer arietinum L.) seeds
… chickpea by improving its nutritional quality, seed RFO (Raffinose Family Oligosaccharides) concentration needs to be reduced without affecting their role during seed development and positive impact on human health. To achieve this objective, the key regulating step(s) of RFO biosynthesis needs …

Global transcriptional, post-transcriptional, and translational regulation during soybean seed and seedling development
… at the appropriate levels during soybean seed and seedling developmental stages. To define the developmental shifts in gene expression and begin to understand the gene regulatory networks, high-throughput RNA sequencing (RNA-Seq) was carried out using cotyledons from seven developmental …

Investigating the Role of the VAL1 Transcription Factor in Arabidopsis thaliana Embryo Development
Developing oilseeds accumulate oils and seed storage proteins synthesized by the pathways of primary metabolism. Seed development and metabolism are positively regulated at the transcriptional level through the transcription factors belonging to the LAFL regulatory network. The VAL genes encode …
