Summary Methionine‐derived glucosinolates belong to a class of plant secondary metabolites that serve as chemoprotective compounds in biotic defense reactions and also exhibit strong anticancerogenic properties beneficial human health. In screen for the trans ‐activation potential various transcription factors toward glucosinolate biosynthetic genes, we could identify HAG1 ( HIGH ALIPHATIC GLUCOSINOLATE 1 , referred MYB28 ) gene positive regulator aliphatic methionine‐derived glucosinolates....
Summary Glucosinolates are a class of plant secondary metabolites that serve as antiherbivore compounds in defence. A previously identified Arabidopsis thaliana activation‐tagged line, displaying altered levels metabolites, was shown here to be affected the content indolic and aliphatic glucosinolates. The observed chemotype caused by activation R2R3‐MYB transcription factor gene HIG1 ( HIGH INDOLIC GLUCOSINOLATE 1 , also referred MYB51 ). HIG1/MYB51 activate promoters glucosinolate...
With the establishment of advanced technology facilities for high throughput plant phenotyping, problem estimating biomass individual plants from their two dimensional images is becoming increasingly important. The approach predominantly cited in literature to estimate a as linear function projected shoot area images. However, estimation error this model, which solely area, large, prohibiting accurate plants, particularly salt-stressed plants. In paper, we propose method based on specific...
Drought is one of the most severe stresses, endangering crop yields worldwide. In order to select drought tolerant genotypes, access exotic germplasm and efficient phenotyping protocols are needed. this study high-throughput platform "The Plant Accelerator", Adelaide, Australia, was used screen a set 47 juvenile (six week old) wild barley introgression lines (S42ILs) for stress responses. The kinetics growth development evaluated under early well watered treatments. High correlation (r=0.98)...
Abstract High-throughput phenotyping produces multiple measurements over time, which require new methods of analyses that are flexible in their quantification plant growth and transpiration, yet computationally economic. Here we develop such apply this to a rice population genotyped with 700k SNP high-density array. Two diversity panels, indica aus , containing total 553 genotypes, phenotyped waterlogged conditions. Using cubic smoothing splines estimate identify four time intervals...
The use of high-throughput phenotyping systems and non-destructive imaging is widely regarded as a key technology allowing scientists breeders to develop crops with the ability perform well under diverse environmental conditions. However, many these studies have been optimized using model plant Arabidopsis thaliana. In this study, Plant Accelerator® at University Adelaide, Australia, was used investigate growth phenotypic response important cereal crop, Sorghum bicolor L. Moench related...
Abstract Background Soil salinity is an abiotic stress wide spread in rice producing areas, limiting both plant growth and yield. The development of salt-tolerant requires efficient high-throughput screening techniques to identify promising lines for salt affected areas. Advances made image-based phenotyping provide opportunity use non-destructive imaging screen tolerance traits a range germplasm reliable, quantitative way. However, the application remains limited. Results A protocol assess...
Salinity affects a significant portion of arable land and is particularly detrimental for irrigated agriculture, which provides one-third the global food supply. Rice (Oryza sativa), most important crop, salt sensitive. The genetic resources tolerance in rice germplasm exist but are underutilized due to difficulty capturing dynamic nature physiological responses stress. basis these predicted be polygenic. In an effort address this challenge, we generated temporal imaging data from 378...
Summary Cereal varieties with improved salinity tolerance are needed to achieve profitable grain yields in saline soils. The expression of AVP 1 , an A rabidopsis gene encoding a vacuolar proton pumping pyrophosphatase ( H + ‐ PP ase), has been shown improve the transgenic plants greenhouse conditions. However, potential for this yield cereal crops field yet be evaluated. Recent advances high‐throughput nondestructive phenotyping technologies also offer opportunity quantitatively evaluate...
Soil salinity results in reduced productivity chickpea. However, breeding for tolerance is challenging because of limited knowledge the key traits affecting performance under elevated salt and difficulty high-throughput phenotyping large, diverse germplasm collections. This study utilised image-based to genetic variation chickpea 245 accessions. On average plant growth rate (obtained from tracking leaf expansion through time) by 20%, height 15% shoot biomass 28%. Additionally, induced pod...
By means of yeast (Saccharomyces cerevisiae) two-hybrid screening, we identified basic helix-loop-helix transcription factor05 (bHLH05) as an interacting partner MYB51, the key regulator indolic glucosinolates (GSLs) in Arabidopsis (Arabidopsis thaliana). Furthermore, show that bHLH04, bHLH05, and bHLH06/MYC2 also interact with other R2R3-MYBs regulating GSL biosynthesis. Analysis bhlh loss-of-function mutants revealed single retained levels were similar to those wild-type plants, whereas...
Barley (Hordeum vulgare L.) is the fourth most important cereal crop worldwide. production compromised by many abiotic stresses including drought. Wild barley a valuable source of alleles that can improve adaptation cultivated to drought stress.In present study, nested association mapping population named HEB-25, consisting 1420 BC1S3 lines were developed crossing 25 different wild accessions elite cultivar 'Barke', was evaluated under both control and drought-stressed conditions in...
Wheat occupies a special role in global food security since, addition to providing 20% of our carbohydrates and protein, almost 25% the production is traded internationally. The importance wheat for was recognised by Chief Agricultural Scientists G20 group countries when they endorsed establishment Initiative 2011. tasked with supporting research community facilitating collaboration, information resource sharing helping build capacity address challenges facing an increasingly variable...
There is increasing evidence of the important roles glutamate receptors (GLRs) in plant development and adaptation to stresses. However, studies these putative ion channels, both planta Xenopus oocytes, may have been limited by our lack knowledge possible GLR heteromer formation plants. We developed a modification single-cell sampling technique investigate co-expression, thus potential formation, single cells Arabidopsis thaliana leaves. Micro-EXpression amplification (MEX) has allowed us...
The spike of a cereal plant is the grain-bearing organ whose physical characteristics are proxy measures grain yield. ability to detect and characterise spikes from 2D images plants, such as wheat, therefore provides vital information on tiller number yield potential. We have developed novel detection method for wheat plants involving, firstly, an improved colour index segmentation and, secondly, neural network-based using Laws texture energy detection. step was further by removing noise...
