Single‐Cell Transcriptome Atlas and Regulatory Dynamics in Developing Cotton Anthers

open access: yesAdvanced Science, Volume 11, Issue 3, January 19, 2024.
Anther development and function have central role in plant reproduction. Here, the first exploration of the spatial expression profiles and regulatory dynamics of different cell types during cotton anther development and in response to high temperature open a new chapter in plant anther research and provides crucial clue for breeding heat‐tolerant ...

Symbolic Thickening of Public Culture and the Rise of Right-Wing Populism in Poland

open access: yesEast European Politics and Societies, 2019
A key feature of thin populist ideology is a sharp division of the social world into “good people” and “bad elites.” Populist ideology “thickens” when it is combined with another ideology, for instance, when this basic distinction is formulated in terms ...

The paleoecologic significance of Paleocene palynomorph assemblages from the Ludow, Slope, and Cannonball formations, southwestern North Dakota [PDF]

open access: yes, 1995
Paleoenvironment exerted control on the distribution of 133 palynomorph taxa from the Ludlow and Slope Formations and Boyce and Three V Tongues of the Cannonball Formation (Fort Union Group, I Paleocene) of southwestern North Dakota. The strata represent

Density waves in shear-thickening suspensions

open access: yesScience Advances, 2020
Flows during discontinuous shear-thickening transition are heterogeneous, unsteady, and loose azimuthal symmetry. Shear thickening corresponds to an increase of the viscosity as a function of the shear rate.

Topological Linking Drives Anomalous Thickening of Ring Polymers in Weak Extensional Flows. [PDF]

open access: yesPhysical Review Letters, 2019
Molecular dynamics simulations confirm recent extensional flow experiments showing ring polymer melts exhibit strong extension-rate thickening of the viscosity at Weissenberg numbers Wi≪1.

Systematics and Palynology of Picrodendron Further Evidence for Relationship with the Oldfieldioideae (Euphorbiaceae) [PDF]

open access: yes, 1984
Although known to botanical science for 285 years, the genus Picrodendron Planchon has been poorly understood for most of this time. The most pervasive problem has been that of discerning familial relationships, and there have been additional ...

ABCG Transporters Are Required for Suberin and Pollen Wall Extracellular Barriers in Arabidopsis [PDF]

open access: yes, 2014
Effective regulation of water balance in plants requires localized extracellular barriers that control water and solute movement. We describe a clade of five Arabidopsis thaliana ABCG half-transporters that are required for synthesis of an effective ...
