Molecular characterization and transcription analysis of DNA methyltransferase genes in tomato (Solanum lycopersicum)
Provedor de dados: 74

Abstract DNA methylation plays an important role in plant growth and development, gene expression regulation, and maintenance of genome stability. However, only little information regarding stress-related DNA methyltransferases (MTases) genes is available in tomato. Here, we report the analysis of nine tomato MTases, which were categorized into four known subfamilies. Structural analysis suggested their DNA methylase domains are highly conserved, whereas the N-terminals are divergent. Tissue-specific analysis of these MTase genes revealed that SlCMT2, SlCMT3, and SlDRM5 were expressed higher in young leaves, while SlMET1, SlCMT4, SlDRM7, and SlDRM8 were highly expressed in immature green fruit, and their expression declined continuously with further fruit...

Transcriptomics analysis of Psidium cattleyanum Sabine (Myrtaceae) unveil potential genes involved in fruit pigmentation
Provedor de dados: 74
Autores: Vetö,Nicole M.; Guzman,Frank; Kulcheski,Franceli R.; Segatto,Ana Lúcia A.; Lacerda,Maria Eduarda G.; Margis,Rogerio; Turchetto-Zolet,Andreia C.
Abstract Psidium cattleyanum Sabine is an Atlantic Forest native species that presents some populations with red fruits and others with yellow fruits. This variation in fruit pigmentation in this species is an intriguing character that could be related to species evolution but still needs to be further explored. Our goal was to provide genomic information for these morphotypes to understand the molecular mechanisms of differences in fruit colour in this species. In this study, we performed a comparative transcriptome analysis of red and yellow morphotypes of P. cattleyanum, considering two stages of fruit ripening. The transcriptomic analysis performed encompassing leaves, unripe and ripe fruits, in triplicate for each morphotype. The transcriptome...

Application of Mindstorms sensors in monitoring the fruit ripening process
Provedor de dados: 111
Autores: Grujicic, Rade; Mijanovic Markus, Marina; Andjic, Branko.
In the present study, investigations were conducted to analyse the possibility of using the Lego Mindstorms light and color sensors in agriculture. The appropriate design was made which consisting of these sensors and control units that provided the information on measured values. The changes in color of tomato fruit (Lycopersicon esculentum Mill.) during maturation process were registered by using the appropriate color and light sensors with the analysis of the possibility of monitoring fruit ripening process and registration of any pathological changes of color. The values measured by sensors are presented in a graphical form, providing an analogy between the results given by Lego Mindstorms color sensor and Lego Mindstorms light sensor. The reliability...

Expression analysis of a set of genes related to the ripening of bananas and mangoes
Provedor de dados: 61
Autores: Godoy,Adriana de; Morita,Rodrigo J.; Cordenunsi,Beatriz R.; Lajolo,Franco M.; Nascimento,João Roberto O. do.
During ripening many important physic-chemical changes contribute to fruit quality, and they are precisely determined by gene expression. Specific genes are essential to normal ripening; however, information on gene expression about the majority of tropical fruit, such as bananas and mangoes is limited. In this way, the present study was undertaken with the objective to provide preliminary access to the changes in expression of some genes potentially relevant to banana and mango ripening. To simultaneously evaluate the changes in gene expression, a small collection of genes related to ethylene biosynthesis, starch mobilization, cell wall disassembly, pigment synthesis and ascorbate metabolism was assembled in nylon membranes and probed with cDNA from...

Cell wall biochemistry of sapodilla (Manilkara zapota) submitted to 1-methylcyclopropene
Provedor de dados: 61
Autores: Morais,Patrícia L.D.; Miranda,Maria R.A.; Lima,Luis C.O.; Alves,José D.; Alves,Ricardo E.; Silva,José D.
Sapodilla (Manilkara zapota) is a climacteric fruit that ripens shortly after harvest. Studies on its conservation during storage have been mainly restricted to using low temperatures and modified atmospheres. In this study we investigated the influence of 1-methylcyclopropene (1-MCP) on the physiological and biochemical changes that sapodilla cell wall undergoes during ripening and evaluated its potential to preserve sapodilla fruits at postharvest. Fruits were treated with ethylene antagonist 1-MCP at 300 nL L-1 for 12 h and then stored under a modified atmosphere at 25ºC for 23 d. 1-MCP significantly delayed softening of sapodilla for 11 d as a consequence of inhibition of cell wall degrading enzyme activities, and thus 1-MCP-treated fruit exhibited a...
