Automatic Detection of Rice Disease in Images of Various Leaf Sizes [PDF]
arXiv, 2022 Fast, accurate and affordable rice disease detection method is required to assist rice farmers tackling equipment and expertise shortages problems. In this paper, we focused on the solution using computer vision technique to detect rice diseases from rice field photograph images.

Nature Genetics, 2018 The genus Oryza is a model system for the study of molecular evolution over time scales ranging from a few thousand to 15 million years. Using 13 reference genomes spanning the Oryza species tree, we show that despite few large-scale chromosomal ...

Comparison of plant proximal sensing approaches for nitrogen supply detection in crops
Agronomy Journal, Volume 114, Issue 6, Page 3317-3328, November/December 2022., 2022 Abstract Nondestructive proximal sensors can be an efficient source of information of N status in crops for localized and rapid adjustment of fertilization applications. The aim of this study was to compare two transmittance/reflectance‐based sensors (SPAD, ASD) and a florescence‐based sensor (Multiplex) in their ability to measure N content in corn ...

Chloroplast SRP54s are Essential for Chloroplast Development in Rice
Rice, 2020 Background The chloroplast signal recognition particle 54 (cpSRP54) is known for targeting the light-harvesting complex proteins to thylakoids and plays a critical role for chloroplast development in Arabidopsis, but little is known in rice.

Rice yields decline with higher night temperature from global warming.
Proceedings of the National Academy of Sciences of the United States of America, 2004 The impact of projected global warming on crop yields has been evaluated by indirect methods using simulation models. Direct studies on the effects of observed climate change on crop growth and yield could provide more accurate information for assessing ...

Profit‐maximizing potassium fertilizer recommendations for corn and cotton
Agronomy Journal, Volume 114, Issue 6, Page 3358-3376, November/December 2022., 2022 Abstract Whereas K fertilization is necessary to maximize corn (Zea mays L.) and cotton (Gossypium hirsutum L.) yields in soils with sub‐optimum K availability, maximizing yield is rarely profit‐maximizing. Estimating the tradeoff between yield and fertilizer cost using current soil‐building and/or yield‐maximizing rate recommendations vs.

A Receptor Kinase-Like Protein Encoded by the Rice Disease Resistance Gene, Xa21
Science, 1995 The rice Xa21 gene, which confers resistance to Xanthomonas oryzae pv. oryzae race 6, was isolated by positional cloning. Fifty transgenic rice plants carrying the cloned Xa21 gene display high levels of resistance to the pathogen.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT This study assessed whether continued treatment with anti‐CGRP monoclonal antibodies (mAbs) is driven more by reductions in monthly migraine days (MMDs) or patients' global impression of change (PGIC), a patient‐reported outcome. Among 169 patients treated with anti‐CGRP mAbs, 21.3% discontinued due to ineffectiveness. PGIC responders (≥ 5) at
