The involvement of ethylene in fruit ripening is well documented, though knowledge regarding the crosstalk between and other hormones lacking. We discovered that AUXIN RESPONSE FACTOR 2A (ARF2A), a recognized auxin signaling component, functions control ripening. ARF2A expression regulated reduced rin, nor nr mutants. It also responsive to exogenous application ethylene, abscisic acid (ABA). Over-expressing tomato resulted blotchy which certain regions turn red possess accelerated...
Late watergrass [ Echinochloa phyllopogon (Stapf.) Koss.] is a major weed of California rice that has evolved P450-mediated metabolic resistance to multiple herbicides. Resistant (R) populations are also poorly controlled by the recently introduced herbicide penoxsulam. Ratios (R/S) R susceptible (S) GR(50) (herbicide rate for 50% growth reduction) ranged from 5 9. Although specific acetolactate synthase (ALS) activity was 1.7 higher in than S plants, enzyme plants about 6 times more...
The plant hormone auxin is a major regulator of development and response to environmental cues. Auxin plays particularly central role in flower development, but the knowledge its crop plants with fleshy fruits, such as tomato, still scarce. Mutations Aux/IAA gene ENTIRE/Indole Acetic Acid 9 (E/IAA9) lead precocious young gynoecia into parthenocarpic fruits. Here, we compared distribution sensor DR5::VENUS efflux transporter PIN1 between wild type entire during successive stages fruit...
Steroidal glycoalkaloids (SGAs) are protective metabolites constitutively produced by Solanaceae species. Genes and enzymes generating the vast structural diversity of SGAs have been largely identified. Yet, mechanisms hormone pathways coordinating defence (jasmonate; JA) growth (gibberellin; GA) controlling metabolism remain unclear. We used tomato to decipher hormonal regulation during vs tradeoff. This was performed genetic biochemical characterisation different JA GA components, coupled...
Abstract BACKGROUND: Quinclorac (3,7‐dichloro‐quinoline‐carboxylic acid) is a selective herbicide widely used to control annual grasses and certain broadleaf weeds. Echinochloa phyllopogon (Stapf) Koss. the most noxious grass weed in California rice fields has evolved resistance multiple herbicides with different modes of action. A quinclorac‐resistant (R) E. biotype found Sacramento Valley field where quinclorac never been applied was investigated. RESULTS: Resistant susceptible (S) GR 50...
Abstract BACKGROUND: Late watergrass [ Echinochloa phyllopogon (Stapf.) Koss.] is a major weed of Californian rice that has evolved P450‐mediated metabolic resistance to multiple herbicides. Resistant (R) populations are also poorly controlled by the recently introduced herbicide clomazone. The authors assessed whether this cross‐resistance was P450 mediated, and R plants had reduced sensitivity photooxidation. Understanding mechanism(s) facilitates design management strategies delay...
Producers of horticultural products face new and growing standards regarding food quality safety as well environmental responsibility sustainability. The objective this research was to reduce pollution by increasing nitrogen use efficiency (NUE) in vegetables without negatively affecting fruit yield or quality. Bell pepper used a case study for intensive vegetable cropping. Pepper cultivars with different vegetative vigor were drip-irrigated solutions containing 9.2, 56.2, 102.3, 158.5 mg·L...
The olive tree is generally characterized by relatively low final fruit set consequential to a significant rate of undeveloped pistils, pistil abortion, and flower fruitlet abscission. These processes are acknowledged be governed competition for resources between the developing vegetative reproductive organs. To study role phosphorus (P) nutritional level on development, trees were grown under four levels P three years in large containers. Phosphorus was positively related bud break,...
Echinochloa phyllopogon (late watergrass) is a major weed of California rice (Oryza sativa) that has evolved cytochrome P450-mediated metabolic resistance to different herbicides with multiple modes action. E. populations from Sacramento Valley fields have also recently shown the herbicide clomazone. Clomazone proherbicide must be metabolized 5-ketoclomazone, which active compound inhibits deoxyxylulose 5-phosphate synthase, key enzyme nonmevalonate isoprenoid pathway. This study evaluated...
The linkage between K and the development of storage roots in root crops is partially understood, hence this experiment determined some mechanisms involved cassava. effects 10, 40, 70, 100, 150 200 mg l-1 fertigation on photosynthetic attributes, soluble carbohydrates, starch, metabolites, growth yield were studied a greenhouse. Storage yield, number roots, stomatal conductance net photosynthesis reached maximum at . However, carbohydrates starch leaves significantly declined with an...
Abstract Yield reduction caused by late application of glyphosate to glyphosate-resistant cotton (Gossypium hirsutum; GRC) expressing CP4 5-enol-pyruvylshikmate-3-P synthase under the cauliflower mosaic virus-35S promoter has been attributed male sterility. This study was aimed elucidate factors and mechanisms involved in this phenomenon. Western tissue-print blots demonstrated a reduced expression transgene anthers GRC compared ovules same plants. Glyphosate grown at high temperature regime...
Peanuts ( Arachis hypogaea) are of significant agricultural importance due to their versatile uses, providing a valuable source edible oil and protein-rich food products serving in industrial applications. susceptible various diseases, one them being net syndrome, poorly understood threat triggered by an undefined causal agent, with symptoms including black coloring lesions the peanut pod that affect product quality. In this study, amplicon sequencing was harnessed explore fungal bacterial...
This paper reports one-step synthesis of polysaccharide-based nanovehicles, capable transporting ionic zinc via plant cuticle without auxiliary stimulation. Delivery highly hydrophilic nutritive microelements the hydrophobic foliage is one major challenges in modern agriculture. In traditional nutrition roots, up to 80% permeate soil and get wasted; therefore, foliar treatment an environmentally economically preferable alternative. Carboxymethyl cellulose (CMC) was modified amphiphilic...
Oil in fruits and seeds is an important source of calories essential fatty acids for humans. This specifically holds true olive oil, which appreciated its superior nutritional value. Most orchards are cultivated to produce the outcome fruit yield oil content. Little information available on effect nitrogen (N) The response trees different rates N was therefore studied soilless culture (3 years) commercial field (6 experiments. In both experiments, level biosynthesis were negatively...
In Mediterranean regions, many tomato plants are grown throughout the hot summer period (May–September) in sheltered cultivation, mainly for plant protection reasons. Most of shelters that used low cost net houses covered with 50 mesh insect proof net. most cases these have a flat roof and no ventilation or climate control measures. This insufficient during leads to above optimal air temperatures causes moderate heat stress inside shelters, which yield reduction. The aim this study was...
This paper presents the electrical performance of organic photovoltaic modules (OPVs) on top a polyethylene covered greenhouse high tunnel in Mediterranean climate. Modules from previous study were kept and monitored together with new improved connectors installed roof frames adjacent to greenhouse. Measured module power conversion efficiencies ranged 1% 3%. The typical combined output across 105Wh sunny day 81Wh cloudy day. Module burn-in period was about 15 days, losing around 36% its...
