Background: Epichloë endophytes provide many benefits to host plants, including enhanced insect resistance. Fungal alkaloids are usually thought to be responsible for the endophyte-conferred herbivore resistance. Nonetheless, the fungal alkaloid profiles and concentrations may vary considerably among grass-endophyte systems.

Methods: Data were drawn from the COVID-19 Mother Baby Outcomes (COMBO) Initiative. 1007 participants completed the newborn hearing screen as part of routine clinical care (COMBO-EHR cohort) and 555 completed the National Survey of Children's Health (NSCH) at 2 and/or 3 years of age for research purposes (COMBO-RSCH cohort).
Article Synopsis
- - Allotetraploid white clover formed during the last glaciation through hybridization of two diploid progenitors from different environments: coastal and alpine.
- - The study investigated how molecular changes from hybridization affected white clover's ability to thrive in new niches after glaciation, focusing on frost responses.
- - Key findings included the discovery that the alpine progenitor's descendants produced more galactinol synthase and raffinose in response to cold, likely aiding their survival and expansion compared to the coastal progenitor.
Article Synopsis
- Plants often have to choose between growing bigger and defending themselves against pests.
- The Epichloë fungi help certain grasses grow without making them less resistant to bugs, which is a big deal.
- In experiments, grasses with Epichloë could grow more without getting eaten up by aphids, while non-fungi grasses weren't as lucky and attracted more aphids when they grew.
N-carbamylglutamate (NCG) is postulated to improve fetal growth in nutrient-restricted gestations when supplemented from day 35 to 110 of gestation, but the effects of supplementation from 100 days of gestation to birth have not been evaluated. The aim of this study was to evaluate the effect of oral NCG supplementation from 100 days of gestation (dga) to term in naturally nutrient-restricted grazing twin-bearing ewes, on the maternal body weight (BW), body condition score (BCS), placental morphology, fetal body and organ weights and blood biochemistry and antioxidant status in the ewe and fetuses. Eighteen twin-bearing ewes maintained under grazing management were randomly allocated to either a treatment group (NCG; = 10), orally dosed once daily with 60 mg/kg of NCG from day 100 until 140 dga, or an unsupplemented control group (CON; = 8).
