• With the exception of root hair development, role phytohormone ethylene is not clear in other aspects plant responses to inorganic phosphate (Pi) starvation. The induction AtPT2 was used as a marker find novel signalling components involved Pi Using genetic and chemical approaches, we examined regulation hps2, an Arabidopsis mutant with enhanced sensitivity starvation, identified found be new allele CTR1 that key negative regulator responses. 1-aminocyclopropane-1-carboxylic acid (ACC),...
CLV3/ESR (CLE) proteins are important signaling peptides in plants. The short CLE peptide (12-13 amino acids) is cleaved from a larger pre-propeptide and functions as an extracellular ligand. family large has resisted attempts at classification because the domain too for reliable phylogenetic analysis variable. We used model-based search domains 57 plant genomes entire comprehensive clustering analysis. In total, 1628 genes were identified land plants, with none recognizable green algae....
The cell wall consists of cellulose microfibrils embedded within a matrix hemicellulose and pectin. Cellulose are synthesized at the plasma membrane, whereas polysaccharides in Golgi apparatus secreted. trafficking vesicles containing components is thought to depend on actin-myosin. Here, we implicate microtubules this process through studies kinesin-4 family member, Fragile Fiber1 (FRA1). In an fra1-5 knockout mutant, expansion rate inflorescence stem halved compared with wild type along...
Cell wall assembly requires harmonized deposition of cellulose and matrix polysaccharides. Cortical microtubules orient the by guiding trajectory synthase complexes. Vesicles containing polysaccharides are thought to be transported FRAGILE FIBER1 (FRA1) kinesin facilitate their secretion along cortical microtubules. The microtubule cytoskeleton thus may provide a platform coordinate delivery polysaccharides, but underlying molecular mechanisms remain unknown. Here, we show that tail region...
Setaria viridis (green foxtail) is an important model plant for the study of C4 photosynthesis in panicoid grasses, and fast emerging as a system choice development, domestication, abiotic stress responses evolution. Basic research findings are expected to advance not only this species its close relative S. italica (foxtail millet), but also other many which food or bioenergy crops. Here we report on standardization multiple growth development assays under controlled conditions, response...
Setaria viridis is an emerging model for cereal and bioenergy grasses because of its short stature, rapid life cycle expanding genetic genomic toolkits. Its close phylogenetic relationship with economically important crops such as maize sorghum positions ideal system accelerating discovery characterization crop genes that control agronomically traits. The Second International Genetics Conference was held on March 6-8, 2017 at the Donald Danforth Plant Science Center, St. Louis, MO to discuss...
The morphological and functional diversity of plant form is governed by dynamic gene regulatory networks. In cereal crops, grain and/or pollen-bearing inflorescences exhibit vast architectural developmental complexity, yet the underlying genetic framework only partly known. Setaria viridis a small, rapidly growing grass species in subfamily Panicoideae, group that includes economically important crops such as maize sorghum. S. inflorescence displays complex branching patterns, but its early...
The CLAVATA pathway controls meristem size during inflorescence development in both eudicots and grasses, is initiated by peptide ligands encoded CLV3 / ESR -related ( CLE ) genes. While all shoot meristems Arabidopsis , evidence from cereal grasses indicates that different types are regulated peptides. rice FON2 primarily the of floral meristem, whereas orthologous peptides CLE7 CLE14 maize have their most dramatic effects on branch meristems, hinting at diversification among responses...
Directional transport of auxin is critical for inflorescence and floral development in flowering plants, but the role influx carriers (AUX1 proteins) has been largely overlooked. Taking advantage available AUX1 mutants green millet (Setaria viridis) maize (Zea mays), we uncover previously unreported aspects plant that are affected by influx, including higher order branches inflorescence, stigma branch number, glume (floral bract) development, fertility. However, disruption flux does not...
Aspartate kinase (AK) and homoserine dehydrogenase (HSD) function as key regulatory enzymes at branch points in the aspartate amino acid pathway are feedback-inhibited by threonine. In plants biochemical features of AK bifunctional AK-HSD have been characterized, but molecular properties monofunctional HSD remain unexamined. To investigate role HSD, we cloned cDNA gene encoding (GmHSD) from soybean. Using heterologously expressed purified GmHSD, initial velocity product inhibition studies...
ABSTRACT Construction of the cell wall demands harmonized deposition cellulose and matrix polysaccharides. Cortical microtubules orient by guiding trajectory plasma membrane-embedded synthase complexes. Vesicles containing polysaccharides are thought to be transported FRA1 kinesin facilitate their secretion along cortical microtubules. The microtubule cytoskeleton thus provides a platform coordinate delivery polysaccharides, but underlying molecular mechanisms remain unknown. Here, we show...
