Phenotyping has become the rate-limiting step in using large-scale genomic data to understand and improve agricultural crops. Here, Bellwether Platform for controlled-environment plant growth automated multimodal phenotyping is described. The system capacity 1140 plants, which pass daily through stations record fluorescence, near-infrared, visible images. Plant Computer Vision (PlantCV) was developed as open-source, hardware platform-independent software quantitative image analysis. In a...
The lipid-derived hormone jasmonoyl-L-Ile (JA-Ile) initiates large-scale changes in gene expression by stabilizing the interaction of JASMONATE ZIM domain (JAZ) repressors with F-box protein CORONATINE INSENSITIVE1 (COI1), which results JAZ degradation ubiquitin-proteasome pathway. Recent structural studies show that JAZ1 signal (degron) includes a short conserved LPIAR motif seals JA-Ile its binding pocket at COI1-JAZ interface. Here, we Arabidopsis thaliana JAZ8 lacks this and thus is...
Summary JAsmonate ZIM‐domain (JAZ) proteins repress the activity of transcription factors that execute responses to plant hormone jasmonoyl‐L‐isoleucine (JA‐Ile). The ZIM protein domain recruits co‐repressors NINJA and TOPLESS JAZ‐bound factors, contains a highly conserved TIF[F/Y]XG motif defines larger family TIFY which JAZs belong. Here, we report diverse species contain genes encoding putative non‐TIFY JAZ proteins, including previously unrecognized repressor in Arabidopsis (JAZ13,...
Abstract The plant hormone jasmonate (JA) activates gene expression by promoting ubiquitin-dependent degradation of ZIM domain (JAZ) transcriptional repressor proteins. A key feature all JAZ proteins is the highly conserved Jas motif, which mediates both and binding to transcription factor MYC2. Rapid genes in response JA thought attenuate responses, but little known about mechanisms newly synthesized exert repression presence hormone. Here, we show Arabidopsis (Arabidopsis thaliana) that...
Abstract Gene functional descriptions offer a crucial line of evidence for candidate genes underlying trait variation. Conversely, plant responses to environmental cues represent important resources decipher gene function and subsequently provide molecular targets improvement through editing. However, biological roles large proportions across the phylogeny are poorly annotated. Here we describe Joint Genome Institute (JGI) Plant Atlas, an updateable data resource consisting transcript...
The shoot epidermis of land plants serves as a crucial interface between and the atmosphere: pavement cells protect from desiccation other environmental stresses, while stomata facilitate gas exchange transpiration. Advances have been made in our understanding stomatal patterning differentiation, set 'master regulatory' transcription factors development identified. However, they are limited to specifying differentiation within epidermis. Here, we report identification an Arabidopsis...
Abstract The F-box protein Coronatine Insensitive (COI) is a receptor for the jasmonic acid signaling pathway in plants. To investigate functions of 6 maize (Zea mays) COI proteins (COI1a, COI1b, COI1c, COI1d, COI2a, and COI2b), we generated single, double, quadruple loss-of-function mutants. pollen coi2a coi2b double mutant was inviable. coi1 (coi1-4x) exhibited shorter internodes, decreased photosynthesis, leaf discoloration, microelement deficiencies, accumulation DWARF8 and/or DWARF9, 2...
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...
Novel alleles can now be directly written into related genomes by sequence identity, thus removing the resource-intensive process of trait introduction genetic introgression and eliminate loss diversity that typically results from bottlenecks.
ABSTRACT Gene functional descriptions, which are typically derived from sequence similarity to experimentally validated genes in a handful of model species, offer crucial line evidence when searching for candidate that underlie trait variation. Plant responses environmental cues, including gene expression regulatory variation, represent important resources understanding function and targets plant improvement through editing other biotechnologies. However, even after years effort numerous...
JASMONATE ZIM-DOMAIN (JAZ) proteins are primary transcriptional repressors in the jasmonate (JA) signaling pathway that regulate a broad range of JA-dependent responses. A mechanistic mode action is well established, but what biological roles individual JAZs, and how do they contribute to specification JA outputs? Two recent articles Journal Experimental Botany reveal JAZ7 regulating dark-induced senescence susceptibility fungal pathogens. Jasmonates (JAs) processes, from growth...
Abstract The F-box protein Coronatine Insensitive (COI) is a receptor for the jasmonic acid signaling pathway in plants. To investigate functions of six maize COI proteins (COI1a, COI1b, COI1c, COI1d, COI2a, and COI2b), we made single, double, quadruple loss-of-function mutants. Double-mutant coi2a coi2b pollen was inviable, no homozygous mutant plants were obtained. coi1 ( coi1-4x ) exhibited shortened internode lengths, decreased photosynthesis, leaf discoloration, microelement...
