Abstract Background Brassinosteroids (BRs) play crucial roles in plant development and also promote tolerance to a range of abiotic stresses. Although much has been learned about their development, the mechanisms by which BRs control stress responses regulate stress-responsive gene expression are not fully known. Since BR interacts with other hormones, it is likely that conferring ability lies part its interactions hormones. Results Using collection Arabidopsis mutants either deficient or...
Summary High biomass crops have recently attracted significant attention as an alternative platform for the renewable production of high energy storage lipids such triacylglycerol ( TAG ). While typically accumulates in seeds compounds fuelling subsequent germination, levels vegetative tissues are generally low. Here, we report accumulation more than 15% (17.7% total lipids) by dry weight N icotiana tabacum (tobacco) leaves co‐expression three genes involved different aspects without...
Background Omega-3 long-chain (≥C20) polyunsaturated fatty acids (ω3 LC-PUFA) such as eicosapentaenoic acid (EPA) and docosapentaenoic (DHA) are critical for human health development. Numerous studies have indicated that deficiencies in these can increase the risk or severity of cardiovascular, inflammatory other diseases disorders. EPA DHA predominantly sourced from marine fish although primary producers microalgae. Much work has been done to engineer a sustainable land-based source reduce...
The seeds of Arabidopsis thaliana and many other plants are surrounded by a pectinaceous mucilage that aids in seed hydration germination. Mucilage is synthesized during development within maternally derived coat secretory cells (MSCs), released to surround the upon imbibition. FEI1/FEI2 receptor-like kinases SOS5 extracellular GPI-anchored protein were shown previously act on pathway regulates synthesis cellulose roots. Here, we demonstrate both FEI2 also play role mucilage. Disruption or...
Synthesis and accumulation of plant oils in the entire vegetative biomass offers potential to deliver yields surpassing those oilseed crops. However, current levels still fall well short typically found oilseeds. Here we show how transcriptome biochemical analyses pointed a futile cycle previously established Nicotiana tabacum line, accumulating up 15% (dry weight) storage lipid triacylglycerol leaf tissue. To overcome this metabolic bottleneck, either silenced SDP1 lipase or overexpressed...
The plant hormone brassinosteroid (BR) plays essential roles in growth and development, while also controlling stress responses. This dual ability of BR is intriguing from a mechanistic point view as viable solution for stabilizing crop yields under the changing climatic conditions. Here we report time course analysis responses both no-stress conditions, results which establish that incorporates many stress-related features even are then accompanied by dynamic response unfavourable Found...
Khapra beetle, Trogoderma granarium Everts, 1898, is a serious pest of stored grain products globally. Environmental DNA (eDNA)-based methods offer sensitive detection tools used to inform biosecurity officers on the presence high-risk pests. This study tested laboratory and portable molecular technologies detect khapra beetle environmental extracted from dust samples collected during responses (Tuggeranong Fyshwick) incursions in Australia. Airborne floor were opportunistically using...
Abstract Environmental DNA (eDNA) monitoring has revolutionized the way biodiversity is surveyed and been proposed as a reliable method to inform management decisions. Recognition of eDNA techniques tools biosecurity require stringent standards assess sample quality reliability results. Laboratories can have their workflows assessed certified through accreditation be involved in proficiency testing schemes provided test accuracy precision molecular methods. Currently, there only one...
Chinese tallow ( Triadica sebifera ) is a valuable oilseed-producing tree that can grow in variety of conditions without competing for food production, and promising biofuel feedstock candidate. The fruits are unique they contain both saturated unsaturated fat present the seed layer, respectively. layer poorly studied considered only as an external fatty deposition secreted from seed. In this study we show fact non-seed cellular tissue capable triglyceride synthesis. Knowledge lipid...
Abstract Plants are being engineered for enhanced ethanol production; however, challenges remain in meeting the demand bioenergy that is expected to double by 2030. Therefore, targeting carbon accumulation form of energy-dense oils nonseed biomass considered a superior alternative production. Although triacylglycerols (TAGs) typically stored seed tissues, various tissues such as mesocarp, tubers, stems and leaves also serve storage TAG plants. Moreover, these generally far greater than...
Triacylglycerol (TAG) accumulates in plant seeds as a major renewable source of carbon for food, fuel and industrial feedstock. Approaches to enhance TAG content by altering lipid pathways genes vegetative parts have gained significant attention biofuel other applications. However, consequences these modifications are not always studied detail. In an attempt increase levels leaves we previously demonstrated that novel substrate, monoacylglycerol (MAG), can be used the biosynthesis...
