ABSTRACT

The molecular basis of hybrid vigor (heterosis) has remained unknown despite the importance of this phenomenon in evolution and in practical breeding programs. To formulate a molecular basis of heterosis, an understanding of gene expression in inbred and hybrid states is needed. In this study, we examined the amount of various transcripts in hybrid and inbred individuals (B73 and Mo17) to determine whether the quantities of specific messenger RNAs were additive or nonadditive ...

Nonadditive Gene Expression in Diploid and Triploid Hybrids of Maize
Genetics ; ABSTRACT The molecular basis of hybrid vigor (heterosis) has remained unknown despite the importance of this phenomenon in evolution and in practical breeding programs. To formulate a molecular basis of heterosis, an understanding of gene expression in inbred and hybrid states is needed. In this
Antagonistic Interaction between Abscisic Acid and Jasmonate-Ethylene Signaling Pathways Modulates Defense Gene Expression and Disease Resistance in Arabidopsis
Plant Cell ; The plant hormones abscisic acid (ABA), jasmonic acid (JA), and ethylene are involved in diverse plant processes, including the regulation of gene expression during adaptive responses to abiotic and biotic stresses. Previously, ABA has been implicated in enhancing disease susceptibility in various

Brassinosteroid-regulated gene expression
Plant Physiology ; Major brassinosteroid (BR) effects such as BR-induced growth are mediated through genomic pathways because RNA synthesis inhibitors and protein synthesis inhibitors interfere with these processes. A limited number of BR-regulated genes have been identified hitherto. The majority of genes (such as
The Arabidopsis LATERAL ORGAN BOUNDARIES-domain gene ASYMMETRIC LEAVES2 functions in the repression of KNOX gene expression and in adaxial-abaxial patterning
Plant Cell ; The normal development of lateral organs of the shoot requires the simultaneous repression of meristem-specific genes and the activation of organ-specific genes. ASYMMETRIC LEAVES2 (AS2) is required for the development of normal leaf shape and for the repression of KNOX genes in the leaf. AS2 is a
Photosynthetic Acclimation Is Reflected in Specific Patterns of Gene Expression in Drought-Stressed Loblolly Pine1[w]
Plant Physiology ; Because the product of a single gene can influence many aspects of plant growth and development, it is necessary to understand how gene products act in concert and upon each other to effect adaptive changes to stressful conditions. We conducted experiments to improve our understanding of the
Senescence-associated gene expression during ozone-induced leaf senescence in Arabidopsis
Plant Physiology ; The expression patterns of senescence-related genes were determined during ozone (O^sub 3^) exposure in Arabidopsis. Rosettes were treated with 0.15 (mu)L L^sup -1^ O^sub 3^ for 6 h d^sup -1^ for 14 d.O^sub 3^-treated leaves began to yellow after 10 d of exposure, whereas yellowing was not apparent
The effects of polyethylene glycol on gene expression of developing white spruce somatic embryos
Plant Physiology ; The Effects of Polyethylene Glycol on Gene Expression of Developing White Spruce Somatic Embryos1[w] Somatic embryogenic cultures of white spruce (Picea glauca) represent a valuable system to study molecular mechanisms regulating embryo development because many embryos of defined developmental
Relationship Between Time of Exposure of Laryngopharyngeal Reflux and Gene Expression in Laryngeal Fibroblasts
The Annals of Otology, Rhinology & Laryngology ; Objectives: Acid reflux is damaging to the laryngeal mucosa: however, the significance of the duration of reflux episodes has not been evaluated. The purpose of this study was to determine whether varying the exposure times at low pH with or without pepsin alters gene expression in laryngeal
Repressor- and Activator-Type Ethylene Response Factors Functioning in Jasmonate Signaling and Disease Resistance Identified via a Genome-Wide Screen of Arabidopsis Transcription Factor Gene Expression[w]
Plant Physiology ; To identify transcription factors (TFs) involved in jasmonate (JA) signaling and plant defense, we screened 1,534 Arabidopsis (Arabidopsis thaliana) TFs by real-time quantitative reverse transcription-PCR for their altered transcript at 6 h following either methyl JA treatment or inoculation with
