Cell-Type-Specific Heat-Induced Changes in the Proteomes of Pollen Mother Cells and Microspores Provide New Insights into Tomato Pollen Production Under Elevated Temperature

Proteomes
Background: Tomatoes are self-pollinating plants, and successful fruit set depends on the production of functional pollen within the same flower. Our previous studies have shown that the ‘Black Vernissage’ tomato variety exhibits greater resilience to ...

Modern pollen rain of an upland area: implications of pollen dispersal for interpreting palaeoenvironmental records

Boreas, EarlyView.
A long‐term perspective on landscape evolution is critical for understanding past land‐use activity, land cover–climate feedbacks and, notably, for establishing a factual basis for conservation. Fossil pollen analysis provides a means to achieve this. Biases pertaining to pollen productivity, pollination processes and basin size, however, mean there is

The last glacial cycle in western Norway—extensive MIS 5d glaciation, multiple glacial advances and LGM glacial advance phases

Boreas, EarlyView.
Raised marine MIS 5c sediments evidence extensive preceding (5d) glaciation in western Norway. This is the first out of five (or six) major Weichselian glacier advances that seem to correspond to North Atlantic sea surface cooling periods. Till beds capping the marine sediments show stages of pre‐LGM advance and subsequent retreat.

MCL‐1 inhibition triggers a largely reversible cardiac stress signature in a humanised mouse model

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Myeloid cell leukaemia‐1 (MCL‐1) is an essential anti‐apoptotic protein and a promising therapeutic target in oncology. Early clinical studies of MCL‐1 inhibitors reported unexpected elevations in cardiac troponin, raising concerns about potential cardiotoxicity.

Pollen from adobe brick [PDF]

, 1983
.-Pollen from adobe bricks of the historic Brockman house of Tucson, Arizona, provides clues to the construction history of the building. Seventeen pollen samples were obtained from two separate walls and the mortar joining the bricks of one wall.

Functional interactions among cytoskeleton, membranes, and cell wall in the pollen tube of flowering plants

, 1997
The pollen tube is a cellular system that plays a fundamental role during the process of fertilization in higher plants. Because it is so important, the pollen tube has been subjected to intensive studies with the aim of understanding its biology.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

Children &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Pollen physiology and fertilisation in Vicia Faba L [PDF]

, 1990
In many legume crop species, early-formed fruits or those located closest to the photosynthate are more likely to mature than other fruits. This is so in the Vicia faba crop.

Wall projections in the vegetative cell of Parietaria officinalis L. pollen

, 1980
Ultrastructural aspects of pore development in Parietaria officinalis L. pollen are described. The main feature is the presence of intine wall projections formed in correspondence to the pores during the late microspore stage and persisting in the ...
