Reverse Transcription quantitative PCR (RT-qPCR) is one of the most important techniques for gene expression profiling due to its high sensibility and reproducibility. However, reliability results highly dependent on data normalization, performed by comparisons between profiles genes interest against those constitutively expressed, reference genes. Although technique widely used in fruit postharvest experiments, transcription stability has not been thoroughly investigated under these...
Iron is a well-known metal. Used by humankind since ancient times in many different ways, this element present all living organisms, where, unfortunately, it represents two-way problem. Being an essential block the composition of proteins and metabolic pathways, iron vital component for animals plants. That why deficiency has severe impact on lives including humans, becoming major concern, especially developing countries where access to adequate nutrition still difficult. On other hand,...
Canola is an important oilseed crop and its oil used in human diet biodiesel production. Abiotic stressors severely constrain canola growing causing economic losses. Under adverse conditions, plant cells coordinate their metabolic pathways to produce anti-stress agents. The understanding of the profile can be improve target traits since there a direct relationship with phenotype. Here we take advantage non-targeted metabolite profiling analysis GC–MS technique assess differences accumulation...
Water deficit affects rice growth, development, and yield. Knowledge of genetic diversity for water tolerance, as well the architecture that is responsible this trait, can accelerate cultivars’ improvement. In study, different tools were applied to assess identify genome regions associated with shoot root traits in germplasm grown under at an early vegetative stage. A panel 177 genotypes was evaluated length (RL), dry weight (RDW), (SL), (SDW). Genetic investigated using means grouping...
The orderly progression through mitosis is regulated by the Anaphase-Promoting Complex (APC), a large multiprotein E3 ubiquitin ligase that targets key cell-cycle regulators for destruction 26 S proteasome. APC composed of at least 11 subunits and associates with additional regulatory activators during interphase cycles. Despite extensive research on activator functions in cell cycle, only few components have been functionally characterized plants.Here, we describe an in-depth search genes...
The main aim of this study was to investigate the phenotypic correlation yield component traits using several environmental stratifications methods.We also aimed propose cause and effect relationships for grain components in soybean genotypes under conditions.The tests were conducted agricultural year 2013/2014 four growing sites Rio Grande do Sul, Brazil.The experimental arrangement randomized blocks factorial scheme (11 x 4), consisting eleven environments with repetitions each.All...
Abstract Rice is vital for food security. Due to its tropical origin, rice suffers from cold temperatures that affect entire life cycle. Key genes have been identified involved in tolerance. WRKYs are generally downstream of the MAPK cascade and can act together with VQ proteins regulate stress‐responsive genes. Chilling treatment was applied at germination two genotypes (tolerant sensitive). Shoots S3 stage were collected RNA‐seq identify OsWRKY , OsMAPKs OsVQs expression. Relationships...
Postharvest fruit conservation relies on low temperatures and manipulations of hormone metabolism to maintain sensory properties. Peaches are susceptible chilling injuries, such as 'woolliness' that is caused by juice loss leading a 'wooly' texture. Application gibberellic acid at the initial stages pit hardening impairs woolliness incidence, however mechanisms controlling response remain unknown. We have employed genome wide transcriptional profiling investigate effects application cold...
Iron (Fe) is an essential microelement for all living organisms playing important roles in several metabolic reactions.Rice (Oryza sativa L.) commonly cultivated paddy fields, where Fe goes through a reduction reaction from 3+ to 2+ .Since more soluble, it can reach toxic levels inside plant cells, constituting target studies.Here we aimed verify morphological changes of different rice genotypes focusing on deciphering the underlying molecular network induced upon excess treatments with...
Tolerance to complete submergence is recognized in a limited number of Asian rice (Oryza sativa L.) varieties, most which contain submergence-inducible SUB1A on the polygenic SUBMERGENCE-1 (SUB1) locus. It has been shown that SUB1 locus encodes two Ethylene-Responsive Factor (ERF) genes, SUB1B and SUB1C, all O. varieties. These genes were also found O rufipogon nivara, wild relatives sativa. However, detailed analysis other Oryza species not yet made. Chromosomal location, phylogenetic, gene...
WRKY transcription factor genes compose an important family of transcriptional regulators that are present in several plant species. According to previous studies, these can also perform roles bilberry (Vaccinium myrtillus L.) metabolism, making it essential deepen our understanding fruit ripening regulation and anthocyanin biosynthesis. In this context, the detailed characterization proteins will provide a comprehensive view functional features VmWRKY different organs response intensities...
Stresses can cause large yield reductions in cultivated plants. The response to these stresses occurs via a plethora of signalling pathways, where number genes is induced or repressed. Among the environmental stress responsive genes, there are members ethylene factors (ERF) gene family. mRNA levels different ERF regulated by many hormones and molecules produced under conditions. In this study, with goal identifying rice stress, it was analysed transcriptional expression profile 114 anoxia,...
Responses of rice to submergence have been extensively studied, but the molecular network behind tolerance this stress is still incomplete. Transcription factors (TFs) are important players in gene transcription regulation during stresses. Here, we analyzed expression WRKY genes and morphological anatomical changes different cultivars under submergence. When they were submerged for 48 h, root number, fresh dry masses, aerenchyma development observed. Although accumulations transcripts...
Rice (Oryza sativa L.) presents a strategic role in social and economic levels. The aim of this study was to elucidate the presence genetic variability for genus Oryza, possibility using genotypes with wild characteristics rice breeding programs. Oryza shows great through available most varied environments around world. negative effects imposed by abiotic stresses such as flood, salinity, low temperatures, water deficiency high temperatures may be minimized efficient identification source...
