Resistance of Rice Varieties to \u3ci\u3eSitophilus oryzae\u3c/i\u3e (Coleoptera: Curculionidae) [PDF]

open access: yes, 2016
Rice, Oryza sativa L. (Poaceae), is one of the world’s most important food crops. Among the insects that damage rice grains, the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae), is the most important species.

Assessing environmental and management factors that drive soybean yield gaps in Brazil

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Brazil is the world's largest producer and exporter of soybeans (Glycine max L. Merr.). Assessing yield gaps (Yg) is essential for improving resource use efficiency and guiding farmers’ management strategies. The objective of this study was to estimate soybean yield potential (Yp), water‐limited yields (Yw), and Yg based on water and ...

Delphinidins from Maqui Berry (Aristotelia chilensis) ameliorate the subcellular organelle damage induced by blue light exposure in murine photoreceptor-derived cells

open access: yesBMC Complementary Medicine and Therapies
Background Blue light exposure is known to induce reactive oxygen species (ROS) production and increased endoplasmic reticulum stress, leading to apoptosis of photoreceptors.

Genome-wide characterization and functional analysis of heat shock transcription factors in wild and cultivated rice (Oryza sativa L.)

open access: yesPlant Stress
Due to domestication, the genetic diversity in cultivated rice is lower than that of wild rice species. Recent progress in sequencing the genomes of wild and cultivated rice genus is an important step in identifying their genetic differences associated ...

Sensitivity of redox conditions to irrigation practice and organic matter decomposition in a rotational flooded rice (Oryza sativa) cropping system

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Agricultural practices in the Everglades Agricultural Area (EAA) of South Florida have focused on managing accelerated organic matter (OM) decomposition in Histosols, which leads to soil subsidence. Rotating flooded rice (Oryza sativa L., variety Diamond) during the summer fallow period of sugarcane (Saccharum officinarum L.) has been proposed

Comprehensive survey and evolutionary analysis of genome-wide miRNA genes from ten diploid Oryza species

open access: yesBMC Genomics, 2017
Background MicroRNAs (miRNAs) are non-coding RNAs that play versatile roles in post-transcriptional gene regulation. Although much is known about their biogenesis, and gene regulation very little is known about their evolutionary relation among the ...

Survival and transmission of Xanthomonas oryzae pv. oryzae in rice seeds

open access: yesFundamental and Applied Agriculture, 2019
Xanthomonas oryzae pv. oryzae is a major pathogen of rice that causes bacterial leaf blight (BLB) disease and is a great threat to rice production worldwide. Transmission of X. oryzae pv. oryzae from seed to seed is remain in enigma. In this study, seed transmission was investigated to detect and identified X. oryzae pv.

Improving nitrogen management in US agriculture: Yield Reserve versus land retirement

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Pressure to protect and restore water quality continues to drive demand for greater reductions in nitrogen (N) loads from US agriculture. Researchers have been evaluating agricultural production choices along both the extensive and intensive margins to improve ecosystem services.
