Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

Advanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

Advanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Forage Yield in Two Tropical Grasses at Different Cutting Intervals and N Levels [PDF]

, 2023
Cutting interval and N level determine forage yield in grasses (Whitehead, 1995). Coastcross-1 (Cynodon dactylon and Tifton 68 (Cynodon spp) are tropical grasses of high forage yield potential (Burton, 1972; Burton et al., 1993)

Effect of different ratio and intercropping systems on forage yield and some components of Hungarian vetch (Vicia pannonica Crantz.) and grass combination under arid climate conditions

Растениевъдни науки, 2018
Intercropping productivity under conventional farming system was carried out in the experimental field of The Trakya Agricultural Research Institute (TTAE) in Edirne province in 2012-2015 growing seasons with 3 replications on randomized complete block ...

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off

Advanced Science, EarlyView.
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.

Nitrogen and Phosphorus Application Effects on Pearl Millet Forage Yield and Nutritive Value [PDF]

, 2017
There is limited information on the nitrogen (N) and phosphorus (P) fertilizer requirement of pearl millet forage in dryland systems. Determination of optimum N and P rates for pearl millet forage production in dryland environments of the Great Plains ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Forage production, economic performance indicators and beef cattle nutritional suitability of multispecies annual crop mixtures in northwestern Alberta, Canada

Journal of Applied Animal Research, 2019
A 2-year field study compared annual crop mixtures and monoculture cereal crops (controls) for forage yield and quality value for beef cattle production. Each of the mixtures consisted of 2 to 9 crop species.

Use of a Producer Survey to Reconcile Differences in Experiment Station Yield Estimates [PDF]

Average producer practice reveals that the expected returns are greater from dual-purpose wheat grown for both forage and grain than for grain-only wheat.
