Influence of differential light interception through manipulation of row orientation, spacing, and mulch on weed suppression and peanut yield

Agronomy Journal, Volume 117, Issue 6, November/December 2025.
Abstract Alabama, located in the northern subtropics, is the third‐largest producer of peanut [Arachis hypogaea (L.)] in the United States. Historically, herbicides have been the primary means of weed control in peanut. However, increasing cases of herbicide‐resistant weeds and a lack of commercially available herbicide‐tolerant technology have limited

Resistance to protoporphyrinogen oxidase inhibitors in giant ragweed (Ambrosia trifida)

Pest Management Science, Volume 80, Issue 12, Page 6211-6221, December 2024.
A codon change in PPX2 conferring a R98L substitution was identified as the most likely mechanism conferring protoporphyrinogen oxidase (PPO)‐inhibitor resistance in Ambrosia trifida. Abstract BACKGROUND Giant ragweed (Ambrosia trifida L.) is one of the most troublesome weed species in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] cropping ...

Analysis of the ASMT Gene Family in Pepper (Capsicum annuum L.): Identification, Phylogeny, and Expression Profiles

International Journal of Genomics, Volume 2019, Issue 1, 2019., 2019
Acetylserotonin methyltransferase (ASMT) in plant species, one of the most important enzymes in melatonin biosynthesis, plays a rate‐limiting role in the melatonin production. In this study, based on the whole genome sequence, we performed a systematic analysis for the ASMT gene family in pepper (Capsicum annuum L.) and analyzed their expression ...
