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...

Expression analysis of transcription factors in sugarcane during cold stress

Braz. j. biol; 83 (), 2023
Abstract Transcription factors (TF) are a wide class of genes in plants, and these can regulate the expression of other genes in response to various environmental stresses (biotic and abiotic). In the current study, transcription factor activity in sugarcane was examined during cold stress. Initially, RN...

The pattern of alternative splicing and DNA methylation alteration and their interaction in linseed (Linum usitatissimum L) response to repeated drought stresses

Biol. Res; 56 (), 2023
BACKGROUND: Drought stress has significantly hampered agricultural productivity worldwide and can also result in modifications to DNA methylation levels. However, the dynamics of DNA methylation and its association with the changes in gene transcription and alternative splicing (AS) under drought stress ...

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...

Arabidopsis CK2 family gene CKB3 involved in abscisic acid signaling

Braz. j. biol; 81 (2), 2021
CKB3 is a regulatory (beta) subunit of CK2. In this study Arabidopsis thaliana homozygous T-DNA mutant ckb3 was studied to understand the role of CKB3 in abscisic acid (ABA) signaling. The results shown: CKB3 was expressed in all organs and the highest expression in the seeds, followed by the root. Durin...

Degradation of mitochondrial structure and deficiency of complex I were associated with the transgenic CMS of rice

Biol. Res; 54 (), 2021
BACKGROUND: Mitochondria play a significant role in plant cytoplasmic male sterility (CMS). In our previous study, mitochondrial complex I genes, nad4, nad5, and nad7 showed polymorphisms between the transgenic CMS line M2BS and its wild type M2B. The sterility mechanism of the M2BS at cytological, physi...

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...

Genome-wide characterization of the abscisic acid-, stress- and ripening-induced (ASR) gene family in wheat (Triticum aestivum L)

Biol. Res; 53 (), 2020
BACKGROUND: Abscisic acid-, stress-, and ripening-induced (ASR) genes are a class of plant specific transcription factors (TFs), which play important roles in plant development, growth and abiotic stress responses. The wheat ASRs have not been described in genome-wide yet. METHODS: We predicted the trans...
