The transition of vegetative meristems to a reproductive state followed by floral development and flowering is complex process regulated many regulatory pathways that integrate (epi) genetic environmental factors guarantee the success in angiosperms. In woody perennial species, such as coffee trees, extended life cycle reflects adaptive strategies, i.e., two-year cycle, sequential bud latency during winter, ensure variable environment. dynamics multiple stimuli induce morpho-physiological...
Cultivated tomato, Solanum lycopersicum, is one of the most common fruits in global food industry. Together with wild tomato pennellii, it widely used for developing better cultivars. MicroRNAs affect mRNA regulation, inhibiting its translation and/or promoting degradation. Important proteins involved these processes are ARGONAUTE and DICER. This study aimed to identify characterize genes miRNA processing pathway, molecules target both species. We validated presence pathway different NGS...
Relative gene expression analysis through RT-qPCR is an important molecular technique that helps understanding different mechanisms, such as the plant defense response to insect pests. However, use of for can be affected by factors directly affect reliability results. Among these factors, appropriate choice reference genes crucial and strongly impact relative analyses, highlighting importance in correctly choosing most suitable success analysis. Thus, this study aimed select validate studies...
The influence of extremely low frequency electromagnetic fields on net photosynthesis, transpiration, photosynthetic pigment concentration, and gene expression ribulose 1,5-bisphosphate carboxylase/oxygenase small subunit (RBCS1), during in vitro establishment, multiplication acclimatization phases coffee seedlings were investigated. Untreated plants considered as control, whereas treated exposed to a 60 Hz sinusoidal magnetic field 2 mT induction 3 min. This was generated by an...
Coffee ( Coffea arabica L.) presents an asynchronous flowering regulated by endogenous and environmental stimulus, anthesis occurs once plants are rehydrated after a period of water deficit. We evaluated the evolution Abscisic Acid (ABA), ethylene, 1-aminocyclopropane-1-carboxylate (ACC) content, ACC oxidase (ACO) activity, expression analysis Lysine Histidine Transporter 1 LHT1 ) transporter, in roots, leaves, flower buds from three coffee genotypes C. L. cv Oeiras, Acauã, Semperflorens)...
Gene expression through RT-qPCR can be performed by the relative quantification method, which requires normalization reference genes. Therefore, it is essential to validate, experimentally, candidate Thus, although there are several studies that identify most stable genes, them validate genes for very specific conditions, not exploring whole potential of research since all possible combinations treatments and/or conditions study explored. For this reason, new experiments must conducted...
Seed development may be divided up into embryonic morphogenesis and seed maturation, while diverse genes were connected disconnected in order to bring about such processes. Features as desiccation tolerance, dormancy germination capacity are acquired throughout regulated by the presence interaction of phytohormones abscisic acid (ABA), gibberellin (GA) ethylene. The purpose this study was analyze expression with ABA, GA ethylene biosynthesis during lettuce seeds. For that reason,...
Coffee flowering requires a period of water deficit followed by rainfall to break flower bud dormancy and promote anthesis. Since drought re-watering can increase shoot ethylene production, we investigated changes in root, leaf production expression genes within the biosynthesis signalling pathways their relationship coffee flowering. Drought decreased foliar without changing root even though all tissues likely accumulated precursor ACC (1-aminocyclopropane-1-carboxylic acid), since ACS gene...
ABSTRACT
 Coffee is one of the most economically important commodities. In Brazil, this crop responsible for generating more than eight million jobs. foreign market, Brazil largest producer and exporter coffee. Due to its economic importance, several studies aiming improvement coffee are conducted, but there still problems related productivity quality beverage, such as sequential flowering, which causes production losses a low drink. Thus, understanding molecular mechanisms involved in...
