Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

The EuroBiotech Journal, 2019
Microspore embryogenesis is a model system of plant cell reprogramming, totipotency acquisition, stress response and embryogenesis initiation. This in vitro system constitutes an important biotechnological tool for haploid and doubled-haploid plant ...

Pectin De-methylesterification and AGP Increase Promote Cell Wall Remodeling and Are Required During Somatic Embryogenesis of Quercus suber

Frontiers in Plant Science, 2019
Somatic embryogenesis is a reliable system for in vitro plant regeneration, with biotechnological applications in trees, but the regulating mechanisms are largely unknown.

Rarity begets rarity: Social and environmental drivers of rare organisms in cities

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

Pollen Sporoplasts: Dissolution of Pollen Walls [PDF]

Plant Physiology, 1985
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees

Birch pollen allergy in Europe

Allergy. European Journal of Allergy and Clinical Immunology, 2019
Birch and other related trees of the families Betulaceae and Fagaceae (alder, hazel, oak, hornbeam, chestnut, and beech) constitute the birch homologous group. This grouping is primarily based on the extensive IgE cross‐reactivity of allergen homologs to

Functional expression and subcellular localization of pea polymorphic isoflavone synthase CYP93C18

Biologia Plantarum, 2013
Isoflavone synthase (IFS; CYP93C) plays a key role in the biosynthesis of phenolic secondary metabolites, isoflavonoids. These compounds, which are well-known for their benefits to human health and plant defence, are produced mostly in legumes.

Pollen Grain Microscopic Image Classification Using an Ensemble of Fine-Tuned Deep Convolutional Neural Networks [PDF]

, 2020
Pollen grain micrograph classification has multiple applications in medicine and biology. Automatic pollen grain image classification can alleviate the problems of manual categorisation such as subjectivity and time constraints. While a number of computer-based methods have been introduced in the literature to perform this task, classification ...

Assessing flower‐visiting arthropod diversity in apple orchards through metabarcoding of environmental DNA from flowers and visual census

Environmental DNA, Volume 5, Issue 1, Page 117-131, January 2023., 2023
The diversity of flower‐visiting arthropods in four Danish apple orchards was assessed using molecular (metabarcoding) and non‐molecular techniques. The aim was to obtain a broader overview of arhtropod communities present to support future management practices towards more sustainable agricultural systems.

Flavonols control pollen tube growth and integrity by regulating ROS homeostasis during high-temperature stress

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Plant sexual reproduction is required for seed and fruit production and is highly sensitive to elevated temperatures, suggesting that climate change may have profound agricultural impacts through inhibition of this process.
