Plant Development: Slowing Root Growth Naturally
What determines organ size? A screen for plant strains showing natural variation in root length has identified a novel gene that modulates root growth rate by controlling cell division and elongation at the root tip.
متن کامل2,4-diacetylphloroglucinol alters plant root development.
Pseudomonas fluorescens isolates containing the phlD gene can protect crops from root pathogens, at least in part through production of the antibiotic 2,4-diacetylphloroglucinol (DAPG). However, the action mechanisms of DAPG are not fully understood, and effects of this antibiotic on host root systems have not been characterized in detail. DAPG inhibited primary root growth and stimulated later...
متن کاملPlant Development: How Long Is a Root?
The plant hormone cytokinin controls root growth by balancing the division and differentiation of stem cells. But what controls accumulation of cytokinin? A new study has identified a regulatory loop between a transcription factor, PHABULOSA, and cytokinin biosynthesis that creates robust domains of cytokinin activity.
متن کاملMicroRNAs: at the root of plant development?
Although most genes use RNA in the form of mRNA as a coding intermediate for protein production, there are many genes whose final products are RNA. These noncoding RNAs range from the familiar transfer and ribosomal RNAs to the more recently discovered regulatory RNAs. One type of regulatory RNA was first discovered during the study of nematode larval development. Two approximately 22nucleotide...
متن کاملModeling plant growth and development.
Computational plant models or 'virtual plants' are increasingly seen as a useful tool for comprehending complex relationships between gene function, plant physiology, plant development, and the resulting plant form. The theory of L-systems, which was introduced by Lindemayer in 1968, has led to a well-established methodology for simulating the branching architecture of plants. Many current arch...
