Anatomía y tolerancia a la desecación de semillas de cacao (Theobroma cacao L.) Colegio de Postgraduados
Rangel Fajardo, María Alma.
La adquisición de tolerancia a la desecación en semillas ortodoxas es una estrategia adaptativa que no presentan las semillas del tipo recalcitrantes y por consiguiente son sensibles a la desecación. El grado de tolerancia o sensibilidad a la desecación se ve afectada por varios aspectos de origen genético, fisiológico, bioquímico y anatómico; por consiguiente existen diferencias entre genotipos y entre individuos dentro del genotipo de la misma especie. En este estudio se documentaron características de anatomía de las semillas de cacao, se midió el grado de tolerancia a la desecación y la acumulación de azúcares en relación con tolerancia a la desecación en poblaciones de tres orígenes genéticos de cacao (Theobroma cacao L.). Se emplearon los...

Abstract Flatulence and fullness of stomach is one of the most common problem associated with chickpea primary due to presence of some oligosaccharides and phenols. In this investigation Desi and Kabuli varieties were compared for these oligosaccharides and phenolic compounds. Furthermore, the effect of different processing and cooking methods such as soaking, cooking and germination in the reduction of these antiphysiological factors were are also studies. Maximum tannic acid (0.90 ± 0.20%) was observed in Parbat and C-44 while minimum (0.60 ± 0.04%) in Karak-2. Stachyose contents ranged between 1.10 ± 0.05 (Karak-3) to 1.42 ± 0.02% (Parbat) while raffinose was 0.63 ± 0.05(Karak-3) to 0.81 ± 0.02% (Dasht). The highest tannic acid content was reduced up to...

Effect of raffinose and ultrasound pulses on invertase release by free and immobilized Saccharomyces cerevisiae in loofa (Luffa cylindrica) sponge BABT
Marques,Leila Larisa Medeiros; Buzato,João Batista; Celligoi,Maria Antonia Pedrine Colabone.
This study investigated the effect of raffinose and ultrasound pulses on invertase release from free S. cerevisiae and S. cerevisiae immobilized in Luffa cylindrica. The free cell culture was submitted to 2% raffinose pulse and irradiated for 2 minutes at 0.12 and 0.46 h-1 dilution rates. The immobilized cell culture was submitted to raffinose pulse and irradiated for 1, 2 and 4 minutes, at 0.10 h-1 dilution rate. In immobilized cells, the raffinose pulse increased the invertase activity from 5.38 to 7.27 U/mg. Ultrasound application in free cell culture at the 0.12 h-1 dilution rate gave the best results. The activity varied from 25.08 to 29.38 U/mg while the increase in immobilized cells was from 5.22 to 9.70 U/mg when sonicated for two minutes. These...

Physiological and biochemical changes attenuate the effects of drought on the Cerrado species Vatairea macrocarpa (Benth.) Ducke. Repositório Alice
VIEIRA, E. A.; SILVA, M das G.; MORO, C. F.; LAURA, V. A..
Drought is considered the main abiotic stress because it influences the distribution of plant species and limits the productivity of ecosystems. The aim of this study was to evaluate the effects of drought on physiological and biochemical parameters during the initial development of Vatairea macrocarpa, a native cerrado species. Plants were subjected to daily watering (control); suppression of watering during 90 days with field capacity (fc) 50% and 25% and then followed by rewatering. Relative leaf water content (RWC), gas exchange, photosynthetic pigments content, carbohydrate and amino acids content, antioxidant activities and growth were recorded. The RWC decreased according to the soil water restriction, causing reduction in stomatal conductance and...

Transcriptome Analysis of Leaves, Flowers and Fruits Perisperm of Coffea arabica L. Reveals the Differential Expression of Genes Involved in Raffinose Biosynthesis. Repositório Alice
IVAMOTO, S. T.; REIS JÚNIOR, O.; DOMINGUES, D. S.; SANTOS, T. B. dos; OLIVEIRA, F. F. de; POT, D.; LEROY, T.; VIEIRA, L. G. E.; CARAZZOLLE, M. F.; PEREIRA, G. A. G.; PEREIRA, L. F. P..
Coffea arabica L. is an important crop in several developing countries. Despite its economic importance, minimal transcriptome data are available for fruit tissues, especially during fruit development where several compounds related to coffee quality are produced. To understand the molecular aspects related to coffee fruit and grain development, we report a largescale transcriptome analysis of leaf, flower and perisperm fruit tissue development. Illumina sequencing yielded 41,881,572 high-quality filtered reads. De novo assembly generated 65,364 unigenes with an average length of 1,264 bp. A total of 24,548 unigenes were annotated as protein coding genes, including 12,560 full-length sequences. In the annotation process, we identified nine candidate genes...
