Most research in weed detection, however, focuses on croplands. This research addresses the need for accurate rangeland weed detection models by leveraging convolutional neural network (CNN) models enhanced with transfer learning applied to the DeepWeeds data set taken in situ in regional North Eastern Australia. It investigates the effectiveness of transfer learning across seven popular models, utilizing data augmentation and fine-tuning. The performance of these models was evaluated using accuracy metrics and compared against each other. The results demonstrated that transfer learning, coupled with fine tuning, could be a viable solution for generating efficient weed plant detection models with lower demands on computational resources and smaller datasets, despite the challenging conditions of rangeland environments. EfficientNetV2B1 had the highest classification accuracy of 94.2 ​%, and lowest training times. Moreover, high levels of accuracy were also achieved using InceptionV3, VGG16, and Densenet121, albeit with a training time penalty. This research provides insights into the performance of CNN models in challenging rangeland environments, demonstrates the potential of using transfer learning to enhance weed detection models, and underscores the significance of model selection in agricultural applications of CNNs.</p></div>","PeriodicalId":100341,"journal":{"name":"Crop Design","volume":"3 3","pages":"Article 100060"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772899424000090/pdfft?md5=b5ed423e593946c009845b48ef4441bf&pid=1-s2.0-S2772899424000090-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141414283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its yield remains low and is negatively impacted by climate change. Root phenes are potential targets to improve crop productivity and resilience to environmental stress. However, the sheer number of combinations resulting from interactions of multiple phenes is a challenge for empirical research. <em>In silico</em> approaches are a plausible alternative to assess the utility of different phene combinations in varying states over diverse environmental contexts. Here, we developed an implementation of the functional-structural plant/soil model – OpenSimRoot, for pearl millet in typical sub-Sahelian soil and environmental conditions. Root architectural, anatomical, and physiological parameters were measured using a popular pearl millet variety (Souna 3) and implemented in the model. The above-ground biomass and root length density predicted by the model were similar to data from field trials. The utility of different root phenes was then evaluated for improved phosphorus uptake and plant growth in P deficient soils. Doubled root hair length and density, shallower root angle (−15°) and doubled long lateral root density were found to improve plant growth by 76 ​%, 33 ​% and 33 ​% respectively under low P conditions. Moreover, these phenes showed synergism when combined <em>in silico</em> and led to optimal biomass production in low P supply conditions that resulted in a 75 ​% loss of biomass in the reference variety.

Gaertn), is an important nutraceutical crop with the potential for imparting food and nutritional security. These plants have a comparatively higher tolerance for several abiotic stresses like drought, salinity, and heat. Several players including Transcription Factor (TF) like Nuclear Factor Y (NF-Y) might be associated with this enhanced level of tolerance. Further, it is unclear how phytohormones like Abscisic acid (ABA) regulate the expression of NF-Y, whether in ABA-dependent or ABA-Independent pathway. The interaction of PYL (Pyrabactin resistance1-like) receptor proteins with Nuclear Factor Y (NF-Y) Transcription Factor in the presence of phytohormones like abscisic acid (ABA) provides one insight related to the enhanced tolerance towards abiotic stresses under ABA-dependent signaling in finger millet crop. A total of three PYL receptors of finger millet designated as EcPYL1, EcPYL5, and EcPYL9 were retrieved in the finger millet genome. These receptors were modeled through the SWISS-MODEL using templates 5gwo and 3wg8 and docked with ABA. The best-docked protein-ligand complex PYL5-ABA (binding energy ΔG ​= ​-8.8 kcal mol^-1) was found to be most stable at the 50ns MD simulation study. Further protein-protein interaction between PYL5 and NF-YA2/B3/C1 sub-family members showed a good interaction. This clearly indicates the possibility of the NF-Y-PYL module in the ABA transduction pathway, which performs a crucial role in the expression of stress-responsive genes. These studies reveal the intricate relationship between the ABA, PYL receptors of finger millet, and NF-Y transcription factor in regulating the stress-responsive genes and provide an insight into the abiotic stress tolerance mechanisms, which can be targeted for crop improvement.</p></div>","PeriodicalId":100341,"journal":{"name":"Crop Design","volume":"3 1","pages":"Article 100051"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772899423000290/pdfft?md5=377fe0f6fe5b520a892715bbc5d32b47&pid=1-s2.0-S2772899423000290-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139127488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
