Comparative petiole anatomy of cassava (Manihot) species

open access: yesGenetics and Molecular Research, 2016
In this study, we describe the petiole anatomy of six wild cassava (Manihot) species, one hybrid, and two cultivars of Manihot esculenta, in order to identify their dominant anatomical patterns and relate them to possible adaptations to abiotic factors in the Cerrado biome.

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, EarlyView.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Evaluation of real-time nutrient analysis of fertilized raspberry using petiole sap

open access: yesFrontiers in Plant Science, 2022
The time delay in receiving conventional tissue nutrient analysis results caused red raspberry (Rubus idaeus L.) growers to be interested in rapid sap tests to provide real-time results to guide immediate nutrient management practices.

Occurrence of potassium location in oil palm tissues with reserve sugars: consequences for oil palm K status determination [PDF]

open access: yes, 2014
In some fertilizer trials for oil palm, it is observed that potassium leaf content was not in concordance with potassium application. In some cases no "leaf" response is observed (leaflet potassium content from leaf rank 17 according to specific LD IRHO ...

The Arabidopsis JAGGED gene encodes a zinc finger protein that promotes leaf tissue development [PDF]

open access: yes, 2004
Important goals in understanding leaf development are to identify genes involved in pattern specification, and also genes that translate this information into cell types and tissue structure. Loss-of-function mutations at the JAGGED (JAG) locus result in

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...
