Spike architecture influences grain yield in wheat. We report the map-based cloning of a gene determining number spikelet nodes per spike common The cloned is named TaCOL-B5 and encodes CONSTANS-like protein that orthologous to COL5 plant species. Constitutive overexpression dominant TaCol-B5 allele but without region encoding B-boxes wheat cultivar increases produces more tillers spikes, thereby enhancing transgenic plants under field conditions. Allelic variation results amino acid...
Glutamine is a major amino donor for the synthesis of acids, nucleotides, and other nitrogen-containing compounds in all organisms. In addition to its role nutrition metabolism, glutamine can also function as signaling molecule bacteria, yeast, humans. By contrast, functions remain unclear plants. We demonstrated that could effectively support growth rice seedlings. glutamine-treated roots, contents increased dramatically, whereas levels glutamate remained relatively constant. Transcriptome...
Glutamate is an active amino acid. In addition to protein synthesis and metabolism, increasing evidence indicates that glutamate may also function as a signaling molecule in plants. Still, little known about the nutritional role of genes are directly regulated by rice. Exogenous could serve nitrogen nutrient support growth rice seedlings, but it was not effective ammonium nitrate or glutamine. nitrogen-starved most abundant free acid feeding rapidly significantly increased endogenous levels...
Nitrogen (N) deficiency is one of the most common problems in rice. The symptoms N are well documented, but underlying molecular mechanisms largely unknown Here, we studied early events associated with starvation (-N, 1 h), focusing on amino acid analysis and identification -N-regulated genes rice roots. Interestingly, levels glutamine rapidly decreased within 15 min -N treatment, indicating that part N-deficient signals could be mediated by glutamine. Transcriptome revealed involved...
Ammonium has long been used as the predominant form of nitrogen source for paddy rice (Oryza sativa). Recently, increasing evidence suggests that nitrate also plays an important role acquisition in rhizosphere waterlogged rice. and have a synergistic effect on promoting growth. However, molecular responses induced by simultaneous treatment with ammonium less studied Here, we performed transcriptome analysis to identify genes are rapidly regulated (1.43 mM, 30 min) roots. The combination...
‘Candidatus Liberibacter asiaticus’ (CLas) is a bacterium that causes Huanglongbing, also known as citrus greening, in plants. solanacearum’ (Lso) close relative of CLas and the US it infects solanaceous crops, causing zebra chip disease potato. Previously, we have identified Lso hypothetical protein effector 1 (Lso-HPE1). This uses signal peptide for secretion; disrupts programmed cell death; interacts with tomato RAD23c, d, e proteins, but not RAD23a. In this study, evaluated whether...
‘ Candidatus Liberibacter solanacearum’ (Lso) is a phloem-limited pathogen associated with devastating diseases in members of the Solanaceae and Apiaceae vectored by several psyllid species. Different Lso haplotypes have been identified, LsoA LsoB are responsible for crops. Our efforts aimed at identifying pathogenicity factors used this bacterium to thrive different hosts. Bacterial secreted proteins can play role host colonization or manipulation immune responses; these called effectors....
Abstract Winter bread wheat ( Triticum aestivum L., 2 n = 6 × =42, AABBDD) cultivars “Duster” and “Billings” have occupied significant acreages in the Southern Great Plains for their outstanding yielding ability. In this study, we discovered a major quantitative trait locus (QTL) QYld.osu-1BS grain yield population of 260 doubled haploid (DH) lines derived from cross Duster Billings. When was tested under field conditions years, explained 13.9% 23.5% total phenotypic variation. However, no...
The gram-negative bacterial genus Liberibacter includes economically important pathogens, such as ‘Candidatus asiaticus’ that cause citrus greening disease (or Huanglongbing, HLB) and ‘Ca. solanacearum’ (Lso) zebra chip in potato. pathogens are fastidious bacteria transmitted by psyllids. Pathogen manipulation of the host’ vector’s immune system for successful colonization is hypothesized to be achieved Sec translocon-dependent effectors (SDE). In previous work, we identified hypothetical...
Glutamine, the most abundant free amino acid in humans (Curi et al., 2007 [1]), has many functions. In addition to protein, acid, and nucleic biosynthesis, glutamine also regulates expression of genes related metabolism, cell defense, signal transduction [1]; Brasse-Lagnel 2009 [2]). Glutamine is one major forms nitrogen rice (Fukumorita Chino, 1982 [3]). metabolic nutritional effects, may function as a signaling molecule regulate gene plants. To this end, we used microarray analysis...
