Disentangling Inequality and Exploitation in the Rice Value Chain in Northern Uganda

open access: yesJournal of Agrarian Change, Volume 26, Issue 3, July 2026.
ABSTRACT Although inequality between actors in agricultural value chains has been extensively studied, informal and semiformal arrangements in domestic value chains involving small‐scale actors have been explored less than formal arrangements involving large firms.

Leafcutter Ant Farmers Prevent Loss of Edible Symbiotic Structures by Maintaining Allelic Diversity in Their Multinucleate Fungal Crop

open access: yesMolecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT Leafcutter ants farm the domesticated fungal cultivar Leucoagaricus gongylophorus in subterranean nests containing up to hundreds of discrete garden chambers. The fungal cultivar produces edible symbiotic structures called gongylidia (nutritious swollen hyphal cells consumed by the ants) and expresses a form of polyploidy (multiple ...

Multisite Field Evaluation of Oil Accumulation and Agronomic Performance in Grain and Sweet Sorghums Engineered for Lipid Hyperaccumulation

open access: yesPlant Biotechnology Journal, Volume 24, Issue 7, Page 4546-4560, July 2026.
ABSTRACT Oil sorghum (OS) has been developed by engineering grain (TX430) and sweet (Ramada) genetic backgrounds to accumulate triacylglycerols (TAG) in vegetative tissues as an energy‐dense feedstock for sustainable aviation fuel (SAF) and other biofuels. This study evaluated two TX430 OS lines (TxHO‐2, TxHO‐3) and two Ramada OS lines (RmHO‐1, RmHO‐2)

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

open access: yesPlant, Cell &Environment, Volume 49, Issue 7, Page 4027-4040, July 2026.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Characterization of lodging variation of weedy rice

open access: yesJournal of Experimental Botany, 2022
AbstractWeedy rice (Oryza spp.), one of the most notorious weeds of cultivated rice, evades eradication through stem lodging and seed shattering. Many studies have focused on seed shattering, whereas variations in lodging have received less attention and the underlying mechanisms that cause the differences in lodging between weedy and cultivated rice ...

Weedy rice (Oryza sativa) II. Response of Weedy Rice to Seed Burial and Flooding Depth

open access: yesWeed Science, 2012
Weedy rice is a serious problem of cultivated rice in most of the rice-growing areas in Asia, causing increased production costs and yield losses in rice. A study was conducted to determine the response of weedy rice accessions from India (IWR), Malaysia (MWR), Thailand (TWR), and Vietnam (VWR) to seed burial and flooding depths. The greatest emergence

Competitive N uptake between rice and weedy rice

Field Crops Research, 2006
Abstract Weedy rice, red rice ( Oryza sativa L.), is a serious problem in rice-producing areas of the southern U.S. and various regions worldwide. It competes for production inputs, increases weed control cost, reduces yield and grain quality, and could eliminate economic returns.

Weedy rice: An expanding problem in direct‐seeded rice in the Philippines

Weed Biology and Management, 2020
AbstractWeedy rice is morphologically similar to cultivated rice (Oryza sativa L.). It has biological characteristics that identify it as a weed. Its important weedy characteristics, that is, early and heavy seed shattering, makes it very difficult to control.

ALL ROADS LEAD TO WEEDINESS: STORIES ABOUT WEEDY RICE ORIGINS, WEEDY GENES AND WEED COMPETITIVENESS

open access: yes, 2017
Over the last ten years, charter schools have become a viable choice for parent’s seeking an alternative to traditional public schools. However, research shows this is not the case for students with disabilities. The purpose of this dissertation was to examine special education in charter schools and traditional public schools located in Massachusetts.

Weedy (Red) Rice

open access: yes, 2015
Ongoing increases in the human population necessitate that rice will continue to be a critical aspect of food security for the twenty-first century. While production must increase in the coming decades to meet demand, such increases will be accompanied ...
