Optimizing in vitro shoot regeneration conditions wheat is one of the important steps successful micropropagation and gene transformation. Various factors such as genotypes, explants, phytohormones affect wheat, hindering ability to tailor genotype-independent protocols. Novel computational approaches artificial neural networks (ANNs) can facilitate modeling predicting outcomes tissue culture experiments thereby reduce large experimental treatments combinations. In this study, generalized...
Summary Begomovirus‐associated epidemics currently threaten tomato production worldwide due to the emergence of highly pathogenic virus species and proliferation a whitefly B biotype vector that is adapted tomato. To generate an efficient defence against begomovirus, we modulated activity immune receptor nuclear shuttle protein ( NSP )‐interacting kinase NIK ) in plants; virulence target begomovirus during infection. Mutation T474 within activation loop promoted constitutive ‐mediated...
Nicotinamide adenine dinucleotide (NAD
Thioredoxins (Trxs) modulate metabolic responses during stress conditions; however, the mechanisms governing of plants subjected to multiple drought events and role Trxs under these conditions are not well understood. Here we explored significance mitochondrial Trx system in Arabidopsis following exposure single repeated events. We analyzed previously characterized NADPH-dependent reductase A B double mutant (ntra ntrb) two independent thioredoxin o1 (trxo1) lines. Following similar...
Abstract Plants are constantly exposed to environmental changes that affect their performance. Metabolic adjustments crucial controlling energy homoeostasis and plant survival, particularly during stress. Under carbon starvation, coordinated reprogramming is initiated adjust metabolic processes, which culminate in premature senescence. Notwithstanding, the regulatory networks modulate transcriptional control low remain poorly understood. Here, we show WRKY45 transcription factor highly...
Abstract Despite the fundamental importance of nicotinamide adenine dinucleotide (NAD+) for metabolism, physiological roles NAD+ carriers in plants remain unclear. We previously characterized Arabidopsis thaliana gene (At1g25380), named AtNDT2, encoding a protein located mitochondrial inner membrane, which imports from cytosol using ADP and AMP as counter-exchange substrates NAD+. Here, we further investigated NDT2, by isolating T-DNA insertion line, generating an antisense line...
In Arabidopsis thaliana, two genes encode the E2 subunit of 2-oxoglutarate dehydrogenase (2-OGDH), a multimeric complex composed three subunits. To functionally characterize isoforms subunit, we isolated mutant lines for each gene encoding and performed detailed molecular physiological characterization plants under controlled growth conditions. The functional lack expression 2-OGDH increased plant growth, reduced dark respiration altered carbohydrate metabolism without changes in...
Garlic (Allium sativum L.) is an economically important, monocotyledonous plant with a strong taste and odor. Drought stress adversely affects its growth, development, yield, particularly during the bolting/bulbing stage. Herein we performed RNA-seq to assess transcriptomic changes induced by drought in hardneck garlic plants (Purple Glazer). We observed that significantly reduced photosynthesis rate, fresh weight, leaf water content. Transcriptomic analysis of leaves under normal conditions...
Among the plant molecular mechanisms capable of effectively mitigating effects adverse weather conditions, heat shock proteins (HSPs), a group chaperones with multiple functions, stand out. At time full progress on omic sciences, they look very promising in genetic engineering field, especially order to conceive superior genotypes, potentially tolerant abiotic stresses (AbSts). Recently, some works concerning certain families maize HSPs (ZmHSPs) were published. However, there was still lack...
Quinoa (Chenopodium quinoa Willd.) is a facultative halophyte recognized for its genetic variability and high tolerance to salinity. The objective of this study was evaluate the effect NaCl on three accessions from Camacani germplasm bank National University Altiplano, Perú, at concentrations (0, 200 400 mM) under greenhouse conditions. Four morphological variables (plant height, root length, percentage DM, aerial DM), as well seven metabolic (chlorophyll, proline, phenols, flavonoids,...
Abstract Quinoa ( Chenopodium quinoa ) is a nutritious grain, with balanced composition of amino acids, and facultative halophyte. Under greenhouse conditions, we assessed 148 accessions from the USDA genebank for grain weight, phenological, morphological characteristics. For all traits, analysis variance revealed significant difference among accessions. The matured as late 146 days after planting produced weight up to 19.6 g/plant. Days maturity showed negative correlation per plant,...
Fruit set is an important yield-related parameter, which varies drastically due to genetic and environmental factors. Here, two commercial cultivars of Capsicum chinense (Biquinho Habanero) were evaluated in response light intensity (unshaded shaded) N supply (deficiency sufficiency) understand the role source strength on fruit at metabolic level. We assessed balance primary metabolites leaves during flowering period. Furthermore, we investigated same flowers gain more insights into their...
Crop growth analysis is used for the assessment of crop yield potential and stress tolerance. Capturing continuous plant has been a goal since early 20th century; however, this requires large number replicates multiple destructive measurements. The use machine vision techniques holds promise as fast, reliable, non-destructive method to analyze based on surrogates traits parameters. We infer size along with measurements at time points parameters spring wheat genotypes. measured side-projected...
To examine physiological responses of garlic to salinity, 17-day-old seedlings eight soft-neck accessions were treated with 200 mM NaCl for seven days in a hydroponic system. Several morphological and traits measured at the end treatment, including shoot height, fresh weight, dry root length, photosynthesis rate, concentrations Na+ K+ leaves. The principal component analysis showed that weight K+/Na+ ratio contribute most salt tolerance among accessions. As result, salt-tolerant sensitive...
Herbaceous peony (Paeonia lactiflora Pall.) is a traditional Chinese medicinal herb with roots; however, the flowers, specifically stamens have not been exploited. In this study, main active components of P. (PLS) were identified, and in vitro antioxidant, vivo anti-aging stress resistance properties examined using nematode Caenorhabditis elegans. Our results showed that PLS contains 350 including flavonoids, phenolic acids, terpenoids, alkaloids, others. extracts at concentrations 0.2–1.2...
