Identification, characterization, and expression of Oryza sativa tryptophan decarboxylase genes associated with fluroxypyr‐meptyl metabolism

open access: yesThe Plant Genome, Volume 18, Issue 1, March 2025.
Abstract Tryptophan decarboxylase (TDC) belongs to a family of aromatic amino acid decarboxylases and catalyzes the conversion of tryptophan to tryptamine. It is the enzyme involved in the first step of melatonin (MT) biosynthesis and mediates several key functions in abiotic stress tolerance.

Rapid Screening of 300 Pesticide Residues in Commercially Available Vegetable‐, Fruit‐, and Cereal‐Based Baby Foods by Using Amino‐Functionalized Multiwalled Carbon Nanotubes with QuEChERS and Gas Chromatography‐Electrostatic Field Orbitrap High‐Resolution Mass Spectrometry

open access: yesJournal of Food Quality, Volume 2024, Issue 1, 2024.
A new method for screening 300 pesticide residues in fruit‐, vegetable‐, and cereal‐based baby foods by an improved QuEChERS purification method based on amino‐functionalized multiwalled carbon nanotubes (NH2‐MWCNTs) combined with gas chromatography‐electrostatic field orbitrap high‐resolution mass spectrometry (Orbitrap GC‐MS) was developed.

Cytological and Morphological Effects of Atrazine and Propazine Application on Grain Sorghum.

open access: yesCYTOLOGIA, 1996
Effectiveness on weed control and injury on sorghum plants were compared for herbicides atrazine and propazine which were applied at four different rates, 0.56, 1.1, 2.2 and 4.5kg/ha. It was found that both herbicides at rates above 2.2kg/ha reduced plant height but propazine caused less injury than atrazine.

Propazine Has Little Effect on Growth of Several Containerized Woody Plant Species [PDF]

open access: yesHortTechnology, 1999
Woody plant species were treated in 1995 and 1996 with 0, 1, 2, or 4 lb/acre (0, 1.1, 2.3, or 4.5 kg·ha -1 ) propazine (a.i.). Species studied in 1995 included rose-of-sharon ( Hibiscus syriacus L. `Double Purple'), japanese boxwood (
