Drought stress is major abiotic stress that affects soybean ***,it is widely desirable that soybean becomes more tolerant to *** provide insights into regulatory mechanisms of the stress response,we compared the global gene expression profiles from leaves of two soybean genotypes that display different responses to water-deficit(BR 16 and Embrapa 48,drought-sensitive and droughttolerant,respectively).After the RNA-seq analysis,a total of 5335 down-regulated and 3170 up-regulated genes were identified in the *** the other hand,the number of genes differentially expressed was markedly lower in the Embrapa 48,355 up-regulated and 471 down-regulated ***,induction and expression of protein kinases and transcription factors indicated signaling cascades involved in the drought ***,the results suggest that the metabolism of pectin is differently modulated in response to drought stress and may play a role in the soybean defense mechanism against *** occurs via an increase of the cell wall plasticity and crosslink,which contributed to a higher hydraulic conductance(Kf)and relative water content(RWC%).The drought-tolerance mechanism of the Embrapa 48 genotype involves remodeling of the cell wall and increase of the hydraulic conductance to the maintenance of cell turgor and metabolic processes,resulting in the highest leaf RWC,photosynthetic rate(A),transpiration(E)and carboxylation(A/Ci).Thus,we concluded that the cell wall adjustment under drought is important for a more efficient water use which promoted a more active photosynthetic metabolism,maintaining higher plant growth under drought stress.

Ants show collective and individual behavioral flexibility in their response to immediate context,choosing for example between different foraging *** Pachycondyla striata,workers can forage solitarily or recruit and guide nestmates to larger food sources through tandem *** considered more ancestral and less efficient than pheromone trail-laying,this strategy is common especially in species with small colony *** is not known is how the decision to recruit or follow varies according to the immediate *** is,how fine adjustments in information transfer affect immediate foraging decisions at the colony ***,we studied individually marked workers and evaluated their foraging decisions when food items varied in nature(protein versus carbohydrate),size,and distance from the nest at different temperatures and humidity *** results show that tandem run leaders and potential followers adjust their behavior according to a combination of external *** 84.2%of trips were solitary,most ants(81%)performed at least 1 tandem ***,tandem runs were more frequent for nearby resources and at higher relative ***,when food items were located far away,tandem runs were more successful when heading to protein sources(75%)compared with carbohydrate sources(42%).Our results suggest that the social information transfer between leaders and followers conveys more information than previously thought,and also relies on their experience and motivation.

The fungus-growing ants （Tribe Attini） are a New World group of〉 200 species, all obligate symbionts with a fungus they use for food. Four attine taxa are known to be social parasites of other attines. Acromyrmex （ Pseudoatta） argentina argentina and Acromyrmex （Pseudoatta） argentina platensis （parasites of Acromyrmex lundi）, and Acromyrmex sp. （a parasite of Acromyrmex rugosus） produce no worker caste. In contrast, the recently discovered Acromyrmex insinuator （a parasite of Acromyrmex echinatior） does produce workers. Here, we describe a new species, Acromyrmex ameliae, a social parasite of Acromyrmex subterraneus subterraneus and Acromyrmex subterraneus brunneus in Minas Gerais, Brasil. Like A. insinuator, it produces workers and appears to be closely related to its hosts. Similar social parasites may be fairly common in the fungus-growing ants, but overlooked due to the close resemblance between parasite and host workers.

Sorption has been proposed as a promising approach towards a sustainable water decontamination and recently to the recycling of rare earth elements(REE).Although living seaweed have been shown to be capable of removing REE from contaminated solutions,no studies have yet compared the effects of REE competition on sorption onto different groups of *** effects were analysed in the present study by exposing six living seaweeds(Ulva lactuca,Ulva intestinalis,Fucus spiralis,Fucus vesiculosus,Gracilaria *** Osmundea pinnatifida)(3 g/L,fresh weight) to mono-element and multi-element solutions of Y,La,Ce,Pr,Nd,Eu,Gd,Tb and Dy(1 μmol/L).Results show a preference towards light REE in mono-element solutions,which is reduced when in competition with other *** competitive effect is less pronounced in heavy REE indicating that these are still able to bind to the macroalgae despite the presence of competing *** to water content(%),seaweed specific surface area(cm^(2)/g) shows to be an important factor in the sorption of REE,since larger surface area is associated with higher removal and larger competitive effect.

Trauma to the peripheral nervous system often results in loss of motor and sensory functions of the affected area of the body,leading to a series of functional impairments(Allodi et al.,2012).Injuries to peripheral nerves initiate a series of complex events,known as Wallerian degeneration,which allows the injured axons to regenerate and reinnervate their targets(Allodi et al.,2012).Damage to a nerve induces multiple alterations,which include:axonal degeneration,breakdown of myelin sheath,Schwann cells(SC)proliferation and conversion to a repair phenotype which express cytokines and chemokines that allow the infiltration and activation of macrophages(Mietto et al.,2015;Jessen and Mirsky,2016).

Background: The use of nutritional supplements(NS) among athletes is widespread. However, little is known about the relationship between nutritional adequacy and NS usage. The aims of this study were to evaluate the NS usage and to compare the nutritional intake from food and prevalence of micronutrient inadequacy(PMI) between NS users and ***: Portuguese athletes from 13 sports completed an NS usage questionnaire and a semi-quantitative food-frequency questionnaire assessing information over the previous 12 months. The estimated average requirement cut-point method was used to calculate PMI. General linear models were used to compare nutritional intake and NS usage. Chi-squared tests and logistic regression were performed to study, respectively,relationships and associations between PMI and NS ***: From the 244 athletes(66% males, 13–37 years), 64% reported NS usage. After adjustment, NS users showed a higher intake from food(p < 0.05), for at least 1 gender, for energy, and for 7 of the 17 studied nutrients. The highest PMI were seen for vitamins D and E, calcium, folate,and magnesium. After adjustment, NS users, irrespective of gender, reported lower PMI for calcium(OR = 0.28, 95%CI: 0.12–0.65), and female users for magnesium(OR = 0.06, 95%CI: 0.00–0.98).Conclusion: Athletes using NS reported a higher nutritional intake from food, and a lower PMI for several nutrients. Perhaps, those who were taking NS were probably the ones who would least benefit from it.
