The OsNAC23-Tre6P-SnRK1a feed-forward loop regulates sugar homeostasis and grain yield in rice
Tre6P phosphatase trehalose OsNAC23
2023/3/9
Tre6P (trehalose-6-phosphate) mediates sensing of carbon availability to maintain sugar homeostasis in plants, which underpins crop yield and resilience. However, how Tre6P responds to fluctuations in...
How do we increase food production by more than 50%, on a limited amount of arable land, to feed a projected 10 billion people by 2050?

An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of cr...
Genetic parameters for residual feed intake in a random population of Pekin duck
Genetic Parameters Residual Feed Intake Pekin Duck
2017/3/8
The feed intake (FI) and feed efficiency are economically important traits in ducks. To obtain insight into this economically important trait, we designed an experiment based on the residual feed inta...
Washington State University biologist Mechthild Tegeder has developed a way to dramatically increase the yield and quality of soybeans.
Her greenhouse-grown soybean plants fix twice as much nitrogen ...

This study was conducted to determine the effect of lysozyme addition on in vitro rumen fermentation and to identify the lysozyme inclusion rate for abating methane (CH4) production. An in vitro rumin...
Different Coefficients and Exponents for Metabolic Body Weight in a Model to Estimate Individual Feed Intake for Growing-finishing Pigs
Feed Consumption Group-housing Growth Performance Maintenance Energy Swine
2016/12/28
Estimation of feed intake (FI) for individual animals within a pen is needed in situations where more than one animal share a feeder during feeding trials. A partitioning method (PM) was previously pu...
