Temporal patterns and management effectiveness of insect pests and diseases in Boro rice cultivation: A 5‐year analysis (2019–2023)

Urban Agriculture &Regional Food Systems, Volume 11, Issue 1, 2026.
Abstract Boro rice (Oryza sativa L.) plays a crucial role in ensuring food security in Bangladesh, yet its productivity is challenged by recurring insect pest and disease outbreaks. This study analyzed 5 years (2019–2023) of data to assess the temporal patterns of insect pest and disease outbreaks in Boro rice cultivation in Bangladesh and evaluate the

SwiftM: A Novel Botanical Knowledge Distillation Framework for Biology‐Informed Plant Disease Recognition

IET Image Processing, Volume 20, Issue 1, January/December 2026.
Current plant disease detection systems often overlook botanical expertise, limiting diagnostic accuracy. We propose SwiftM, a novel framework that integrates plant anatomical knowledge into deep learning through botanical knowledge distillation, structure‐aware graph representation and sparse attention over botanical graphs.

Gene expression responses to Rice tungro spherical virus in susceptible and resistant near-isogenic rice plants

Virus Research, 2013
Rice cultivar Taichung Native 1 (TN1) is susceptible to Rice tungro spherical virus (RTSV). TW16 is a backcross line developed between TN1 and RTSV-resistant cultivar Utri Merah. RTSV accumulation in TW16 was significantly lower than in TN1, although both TN1 and TW16 remained asymptomatic.

Hybrid AI Model With CNNs and Vision Transformers for Precision Pest Classification in Crops

Food Science &Nutrition, Volume 13, Issue 11, November 2025.
This study proposes a hybrid deep learning model integrating CNNs, attention mechanisms, and Vision Transformers for accurate classification of five major rice crop pests. The model captures both fine‐grained local features and global spatial relationships, achieving a high accuracy of 95% on an augmented dataset.

Characterization of a protein from Rice tungro spherical virus with serine proteinase-like activity

Journal of General Virology, 2002
The RNA genome of Rice tungro spherical virus (RTSV) is predicted to be expressed as a large polyprotein precursor (Shen et al., Virology 193, 621–630, 1993 ). The polyprotein is processed by at least one virus-encoded protease located adjacent to the C-terminal putative RNA polymerase which shows sequence similarity to viral serine-like proteases. The

Future flooding tolerant rice germplasm: Resilience afforded beyond Sub1A gene

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Developing high‐yielding, flood‐tolerant rice (Oryza sativa L.) varieties is essential for enhancing productivity and livelihoods in flood‐prone ecologies. We explored genetic avenues beyond the well‐known SUB1A gene to improve flood resilience in rice.
