TL;DR: Increasing level of ZJ0273 herbicide increased the stress for the plants of both the cultivars of Brassica as indicated by enhanced accumulation of malondialdehyde content, and the activities of ALS and antioxidant enzymes, soluble protein and sugar contents, photosynthetic system and agronomic characters declined consistently with each successive increase in ZJ 0273 concentration.

TL;DR: In this article, a variety of different enzymatic based approaches to deconstruct crop residues have shown to be effective in increasing the yields of protein recovered, and the authors show that valorisation of selected crop components could form the basis of a crop biorefinery process to capture proteins and other potentially useful compounds.
Abstract: The agricultural production of olives, rapeseed, tomatoes and citrus fruits within Europe is significant, resulting in a considerable amount of residual material. Rapeseed contains a high proportion of protein but the presence of anti-nutritional components, including glucosinolates, limits its use in food and feed applications. In contrast, the protein quantities associated with the other crop residues are much lower, although each of the residues could be separated into different constitutive parts where some have shown higher protein contents. A variety of different enzymatic based approaches to deconstruct crop residues have shown to be effective in increasing the yields of protein recovered. These studies show that valorisation of selected crop components could form the basis of a crop biorefinery process to capture proteins and other potentially useful compounds.

TL;DR: A new method for simultaneous analysis of clopyralid and picloram residues in rape plant, rapeseed and field soil was developed and validated and it was shown that recoveries ranged from 71.3%–109.0% for clopyrals, and 84.5% for piclorams at fortified levels of 0.02 mg/kg.
Abstract: A new method for simultaneous analysis of clopyralid and picloram residues in rape plant, rapeseed and field soil was developed and validated. The residual dynamics and final residues of clopyralid and picloram in rape plant, rapeseed and soil were determined by High Performance Liquid Chromtography-Diode Array Detector (HPLC-DAD) and High Performance Liquid Chromtography-Mass Spectroscopy Detector (HPLC-MSD). The limit of quantification (LOQ) was established as 0.02 mg/kg for soil sample, 0.5 mg/kg for rape and rapeseed sample, respectively. It was shown that recoveries ranged from 71.3%–109.0% for clopyralid, and 84.0%–100.5% for picloram at fortified levels of 0.02–2 mg/kg. From residue trials at two geographical experimental plots in China and laboratory simulated pots, the results showed that the half-lives of clopyralid in rape and soil were 3.66–4.83 and 2.53–5.17 days, respectively, for picloram with half-lives of 5.17–10.73 and 3.45–7.11 days. For tirals applied according to the label recommended, at harvest time the final residues of clopyralid in rapeseed were below 1.82 mg/kg, while the picloram residues could not be detected in rapeseed (

TL;DR: It is concluded that the natural variation of Seed weight is mainly controlled by maternal genotype, which lays a foundation for genetic and breeding studies of seed weight in rapeseed and opens a new field of research on the regulation of seed traits in plants.
Abstract: Seed weight is a very important and complex trait in rapeseed (Brassica napus L.). The seed weight of rapeseed shows great variation in its natural germplasm resources; however, the morphological, cytological and genetic causes of this variation have remained unclear. In the present study, nine highly pure inbred rapeseed lines with large seed weight variation and different genetic backgrounds were selected for morphological, cytological and genetic studies on seed weight. The results showed the following: (1) Seed weight showed an extremely significant correlation and coordinated variation with seed size (including seed diameter, seed surface area and seed volume), but it showed no significant correlation with bulk density, which suggests that seed weight is determined by size rather than bulk density. (2) Seed weight showed a higher correlation with the cell numbers of seed coats and cotyledons than the cell sizes of seed coats and cotyledons, which suggests that cell number is more tightly correlated with final seed weight. (3) Seed weight was mainly controlled by the maternal genotype, with little or no xenia and cytoplasmic effects. This is the first report on the morphological and cytological causes of seed weight natural variation in rapeseed. We concluded that the natural variation of seed weight is mainly controlled by maternal genotype. This finding lays a foundation for genetic and breeding studies of seed weight in rapeseed and opens a new field of research on the regulation of seed traits in plants.
