Factor de conversión proteica y capacidad antioxidante de isoflavonas en Glycine max

The conversion factor of nitrogen to proteins and isoflavones present in Glycine max was determined. For the determination of the conversion factor, we worked with solubilizing the proteins at alkaline pH and then extracting them with acidic pH. The proteins were iden...

Regulon: An overview of plant abiotic stress transcriptional regulatory system and role in transgenic plants

Braz. j. biol; 83 (), 2023
Abstract Population growth is increasing rapidly around the world, in these consequences we need to produce more foods to full fill the demand of increased population. The world is facing global warming due to urbanizations and industrialization and in this concerns plants exposed continuously to abiotic...

TiO2 nanoparticles and salinity stress in relation to artemisinin production and ADS and DBR2 expression in Artemisia absinthium L

Braz. j. biol; 82 (), 2022
Artemisia absinthium L. is an important herb that is widely cultivated in different parts of the world for its medicinal properties. The present study evaluated the effects of four concentrations of nanoparticles treatment (0, 10, 20 and 30 mg L-1) and NaCl salinity stress (0, 50, 100 and 150 mM NaCl) an...

Genome-wide analysis of metallothionein gene family in maize to reveal its role in development and stress resistance to heavy metal

Biol. Res; 55 (), 2022
BACKGROUND: Maize (Zea mays L.) is a widely cultivated cereal and has been used as an optimum heavy metal phytoremediation crop. Metallothionein (MT) proteins are small, cysteine-rich, proteins that play important roles in plant growth and development, and the regulation of stress response to heavy metal...

Molecular structures and functional exploration of NDA family genes respond tolerant to alkaline stress in Gossypium hirsutum L

Biol. Res; 55 (), 2022
BACKGROUND: The internal NAD(P)H dehydrogenase (NDA) gene family was a member of the NAD(P)H dehydrogenase (ND) gene family, mainly involved in the non-phosphorylated respiratory pathways in mitochondria and played crucial roles in response to abiotic stress. METHODS: The whole genome identification, str...

Structure and character analysis of cotton response regulator genes family reveals that GhRR7 responses to draught stress

Biol. Res; 55 (), 2022
BACKGROUND: Cytokinin signal transduction is mediated by a two-component system (TCS). Two-component systems are utilized in plant responses to hormones as well as to biotic and abiotic environmental stimuli. In plants, response regulatory genes (RRs) are one of the main members of the two-component syst...

Identification and characterization of profilin gene family in rice

BACKGROUND Profilin proteins (PRFs) are small (12–15 kD) actin-binding protein, which play a significant role in cytoskeleton dynamics and plant development via regulating actin polymerization. Profilins have been well documented in Arabidopsis, Zea mays L. as well as Phaseolus vulgaris, however no suc...

Characterization of AhLea-3 and its enhancement of salt tolerance in transgenic peanut plants

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Late embryogenesis abundant (LEA) proteins were reported to be related to adversity stress and drought tolerance. Lea-3 from Arachis hypogaea L. (AhLea-3) was previously found to be related to salt tolerance according to the result of transcriptome profiling and digital gene expression analys...

Genome-wide identification and characteristic analysis of the downstream melatonin metabolism gene GhM2H in Gossypium hirsutum L

Biol. Res; 54 (), 2021
BACKGROUND: Melatonin 2-hydroxylase (M2H) is the first enzyme in the catabolism pathway of melatonin, which catalyzes the production of 2-hydroxymelatonin (2-OHM) from melatonin. The content of 2-hydroxymelatonin in plants is much higher than that of melatonin. So M2H may be a key enzyme in the metabolic...

Ectopic expression of Chrysanthemum CDM19 in Arabidopsis reveals a novel function in carpel development

BACKGROUND: APETALA3 (AP3) has significant roles in petal and stamen development in accordance with the classical ABC model. RESULTS: The AP3 homolog, CDM19, from Chrysanthemum morifolium cv. Jinba was cloned and sequenced. Sequence and phylogenetic analyses revealed that CDM19 is of DEF/AP3 lineage poss...
