Assessing behavioral control across reinforcer solutions on a fixed-ratio schedule of reinforcement in rats

Joel E. Shillinglaw, Ian K. Everitt, Donita L. Robinson, J.E. Shillinglaw, more

Alcohol > 2014 > 48 > 4 > 337-344

Instrumental behavior can shift from flexible, goal-directed actions to automatic, stimulus-response actions. The satiety-specific devaluation test assesses behavioral flexibility by evaluating reward seeking after temporary devaluation of the reinforcer via satiety; a decrease in responding compared to control conditions indicates goal-directed behavior. We have observed variability in the outcome...

Racheal A. Herlehy, Stephanie Lim, Shealin H. Murray, Jennet L. Baumbach, more

Developmental Psychobiology > 64 > 6 > n/a - n/a

Although there is evidence of sex differences in responding to social stress, and that age when stressed matters, females are understudied and adult‐stress comparisons are few. Here, we investigated stress effects on reward sensitivity by examining rats’ choice of social versus sucrose reward in a continuous spatial allocation design. We predicted social instability stress (SS) in adolescence would...

Chuntao Tan, Liang Zhang, Xuewu Duan, Xirong Chai, more

Journal of the Science of Food and Agriculture > 102 > 7 > 2855 - 2863

BACKGROUND Pea sprouts are considered a healthy food. Sucrose is a key nutritional factor affecting taste and flavor. Meanwhile, selenium (Se) is an essential micronutrient that plays multiple roles in wide variety of physiological processes and improves crop quality and nutritional value. Nonetheless, the effects of the combination of sucrose and Se treatment on growth, quality, and sugar metabolism...

A transcriptional landscape underlying sugar import for grain set in maize

Si Shen, Si Ma, Xian‐Min Chen, Fei Yi, more

The Plant Journal > 110 > 1 > 228 - 242

Developing seed depends on sugar supply for its growth and yield formation. Maize (Zea mays L.) produces the largest grains among cereals. However, there is a lack of holistic understanding of the transcriptional landscape of genes controlling sucrose transport to, and utilization within, maize grains. By performing in‐depth data mining of spatio‐temporal transcriptomes coupled with histological and...

Overexpression of a wheat α‐amylase type 2 impact on starch metabolism and abscisic acid sensitivity during grain germination

Qin Zhang, Jenifer Pritchard, Jos Mieog, Keren Byrne, more

The Plant Journal > 108 > 2 > 378 - 393

Despite being of vital importance for seed establishment and grain quality, starch degradation remains poorly understood in organs such as cereal or legume seeds. In cereals, starch degradation requires the synergetic action of different isoforms of α‐amylases. Ubiquitous overexpression of TaAmy2 resulted in a 2.0–437.6‐fold increase of total α‐amylase activity in developing leaf and harvested grains...

Root submergence enhances respiration and sugar accumulation in the stem of flooded tomato plants

Francesco Mignolli, Javier Orlando Barone, María Laura Vidoz

Plant, Cell & Environment > 44 > 11 > 3643 - 3654

Flooding is a major environmental constraint that obliges plants to adopt plastic responses in order to cope with it. When partially submerged, tomato plants undergo profound changes involving rearrangements in their morphology and metabolism. In this work, we observed that partial submergence markedly dampens root respiration and halts root growth. However, the flooded hypocotyl surprisingly enhances...

Raman spectroscopy reveals high phloem sugar content in leaves of canopy red oak trees

Jess T. Gersony, Arthur McClelland, N. Michele Holbrook

New Phytologist > 232 > 1 > 418 - 424

A robust understanding of phloem functioning in tall trees evades us because current methods for collecting phloem sap do not lend themselves to measuring actively photosynthesizing canopy leaves. We show that Raman spectroscopy can be used as a quantitative tool to assess sucrose concentration in leaf samples. Specifically, we found that Raman spectroscopy can predict physiologically relevant...

Yongjoong Kim, Jina Park, You Yeon Choi, Younghyun Lee, more

Entomological Science > 24 > 3 > 320 - 329

Drosophila melanogaster has been increasingly used as an experimental model to understand the health effects of environmental stresses such as radiation exposure and the nutrients depletion. Few studies have examined the physiological changes of radiation exposure combined with other condition such as nutrient depletion. To understand the effects of radiation exposure in the context of poor diet,...
