Arabidopsis thaliana EARLY FLOWERING 3 (ELF3) as a zeitnehmer (time taker) is responsible for generation of circadian rhythm and regulation photoperiodic flowering. There are two orthologs (OsELF3-1 OsELF3-2) ELF3 in rice (Oryza sativa), but their roles have not yet been fully identified. Here, we performed functional characterization OsELF3-1 revealed it plays more predominant role than OsELF3-2 heading. Our results suggest can affect systems via positive OsLHY expression negative OsPRR1,...
Grain weight and grain number are two important traits directly determining yield in rice. To date, a lot of genes related to have been identified; however, the regulatory mechanism underlying these remains largely unknown. In this study, we studied biological function OsSPL18 during panicle development Knockout (KO) mutants exhibited reduced width thickness, length number, but increased tiller number. Cytological analysis showed that regulates spikelet hulls by affecting cell proliferation....
Jiang-flavor (JF) daqu is a liquor starter used for production of JF baijiu, well-known distilled in China. Although high temperature stage (70°C) necessary qualifying daqu, little known regarding its active microbial community and functional enzymes, along with role generating flavor precursors baijiu aroma. In this investigation, based on metatranscriptomics, fungi, such as Aspergillus Penicillium, were identified the most members 230 carbohydrate-active enzymes potential saccharifying at...
In this work, the ammonium-tolerant duckweed Landoltia punctata 0202 was used to study effect of ammonium stress on carbon and nitrogen metabolism elucidate detoxification mechanism. The growth status, protein starch content, activity assimilation enzymes were determined, transcriptional levels genes involved in ion transport investigated. Under high stress, inhibited, especially when sole source. Ammonium might mainly enter cells via low-affinity transporters. stimulation potassium...
Here, we combined the aquatic cultivation of energy crop duckweed and nitrogen limitation to quickly produce starch-rich biomass. Under N limitation, can accumulate starch at up 52.37 ± 0.57% (dry weight). In process, use efficiency (NUE) reached 61.3 1.8 kg biomass kg−1 N, exceeding that most cereals. this paper, elucidated for first time mechanism high NUE under limitation. First, possesses higher transport ability than cereals trees efficiently abundant in vivo N-sufficient condition....
Duckweeds are traditionally used as a plant protein source in some Southeast Asian countries. In this study, we first obtained high-protein strain (Wolffia arrhiza 7678a) under artificial conditions and determined its content 50.89% of dry weight. More importantly, further investigated nutritional properties. The digestible indispensable amino acids score (DIAAS) reached 0.75, indicating the good quality W. arrhiza. proportion unsaturated fatty total (TFA) was 70.85%, three main (palmitic...
Cadmium (Cd) is a common and toxic non-essential heavy metal that must be effectively treated to reduce its threat the environment public health. Adsorption with an adsorbent, such as agricultural waste, widely used remove metals from wastewater. Sweet potato, sixth most abundant food crop worldwide, produces large amount of waste during postharvest processing could economic adsorbent. In this study, feasibility using sweet potato residue (SPR) adsorbent for Cd
Introduction The increasing global demand for starch has created an urgent need to identify more efficient and sustainable production methods. However, traditional sources, such as crop-based options, experience significant bottlenecks due limitations in land use, water consumption, the impacts of climate change. Therefore, there is a pressing explore develop new sources starch. Methods We novel duckweed cultivation technology that combines nutrients limitation CO 2 supplementation achieve...
Phosphorus is an essential element for plant growth and reproduction. This study aimed to investigate the metabolic response, growth, starch accumulation mechanisms in duckweed strain, Landoltia punctata 0202, under phosphate starvation. The results revealed that, starvation, total phosphorus L. 0202 decreased, while carbon increased. After 15 days of biomass yield increased from 12.64 to123.87 g m−2, utilization efficiency 761.78 g−1. content accumulated 2.14 38.05 % by Day 15, reached...
Sweetpotato can be cultivated in reclaimed rocky soil Sichuan Basin, China, which benefits from the release of mineral nutritions by microorganisms. Shortage nitrogen (N) limits sweetpotato yield, compensated through N fertilization. Whereas high fertilization inhibit biological fixation and induce unintended environmental consequences. However, effect low on microorganism community yield N-deficient is still unclear. We added a level 15 kg/ha urea to with sweetpotato, measured physiological...
Abstract Terrestialization is supposedly an important evolutionary process plant experience. However, directions of land back to water acquired little attention. Here we integrate multiproxy evidence elucidate the evolution duckweed. Three genera duckweed show chronologically gradient degeneration in roots structure and stomatal function decrease lignocellulose content, accompanied by gradual contraction relevant gene numbers and/or decline transcription. The main phytohormonal pathway are...
OsMADS1 plays a vital role in regulating floret development and grain shape, but whether it regulates rice quality still remains largely unknown. Therefore, we used comprehensive molecular genetics, plant biotechnology, functional omics approaches, including phenotyping, mapping-by-sequencing, target gene seed-specific RNAi, transgenic experiments, transcriptomic profiling to answer this biological question. Here, report the characterization of 'Oat-like rice' mutant, with poor quality,...
Duckweeds, recognized as the fastest growing aquatic flowering plants, exhibit substantial biomass production. Recently, they have been emerged a potential industrial crop for efficient and eco-friendly protein production nutrient recovery compared to conventional crops. The objective of study was determine accumulation rate, content amino acid analysis duckweeds (Lemna minor D0158).We cultured L. D0158 from its preserved state in gene bank into both aseptic (in-vitro) open condition at...
Salt-alkali stress threatens the resilience to variable environments and thus grain yield of rice. However, how rice responds salt-alkali at molecular level is poorly understood. Here, we report isolation a novel salt-alkali-tolerant (SATR) by screening more than 700 germplasm accessions. Using 93-11, widely grown cultivar, as control, characterized SATR in response strong (SSAS). exhibited SSAS tolerance higher indicated survival rate, associated with peroxidase activity total soluble sugar...
Abstract The increasing demand for starch has been a social struggle. We report new technology that efficiently produces from duckweed. Although Landoltia punctata dramatic contraction of gene families, its content and productivity reached 72.2% (dry basis) 10.4 g m -2 d -1 in 10 days, equivalent to yield 38.0 t ha y under nutrient limitation CO 2 elevation treatment. Meanwhile, we also examined the mechanism duckweed’s high accumulation. This is exhibited regulation DNA methylation...
Polyploid rice and its reverted diploid show rich phenotypic variation strong heterosis, showing great breeding value. However, the genomic differences among tetraploids, counterpart common diploids, tetraploid-revertant hybrid descendants are unclear. In this work, we bred a new excellent two-line variety,
Duc kweeds are becoming an emerging plant protein source as it may be produced in a more efficient and eco-friendly manner than other major crops. Screening is essential for tapping the desired traits. We conducted screening on 32 Lemna species accessions available Gene Bank.
