Contrapuntal networks of gene expression during Arabidopsis seed filling.
We have used cDNA microarrays to examine changes in gene expression during Arabidopsis seed development and to compare wild-type and mutant wrinkled1 (wri1) seeds that have an 80% reduction in oil. Between 5 and 13 days after flowering, a period preceding and including the major accumulation of storage oils and proteins, approximately 35% of the genes represented on the array changed at least t...
متن کاملAnalysis of gene expression patterns during seed coat development in Arabidopsis.
The seed coat is important for embryo protection, seed hydration, and dispersal. Seed coat composition is also of interest to the agricultural sector, since it impacts the nutritional value for humans and livestock alike. Although some seed coat genes have been identified, the developmental pathways controlling seed coat development are not completely elucidated, and a global genetic program as...
متن کاملGlobal analysis of gene activity during Arabidopsis seed development and identification of seed-specific transcription factors.
Most of the transcription factors (TFs) responsible for controlling seed development are not yet known. To identify TF genes expressed at specific stages of seed development, including those unique to seeds, we used Affymetrix GeneChips to profile Arabidopsis genes active in seeds from fertilization through maturation and at other times of the plant life cycle. Seed gene sets were compared with...
متن کاملExpression during Seed Cermination’
A maize (Zea mays 1.) cDNA clone (pZMB2) encoding P-amylase was isolated from a cDNA library prepared from the aleurone RNA of germinating kernels. l h e cDNA encodes a predicted product of 488 amino acids with significant similarity to known P-amylases from barley (Hordeum vulgare), rye (Secale cereale), and rice (Oryza sativa). Clycine-rich repeats found in the carboxyl terminus of the endosp...
متن کاملRegulation of gene expression programs during Arabidopsis seed development: roles of the ABI3 locus and of endogenous abscisic acid.
The accumulation kinetics of 18 mRNAs were characterized during Arabidopsis silique development. These marker mRNAs could be grouped in distinct classes according to their coordinate temporal expression in the wild type and provided a basis for further characterization of the corresponding regulatory pathways. The abscisic acid (ABA)-insensitive abi3-4 mutation modified the expression pattern o...
