Impact of homogenization and protein extraction conditions on the obtained tobacco pollen proteomic patterns

open access: yesBiologia Plantarum, 2011
Mature pollen grain represents a highly desiccated structure with an extremely tough cell wall. Thanks to it, it resists common proteomic protocols. Instead, a robust homogenization has to be performed since proteins are needed to burst out of the cell ...

Flood Mapping in the Coastal Region of Bangladesh Using Sentinel-1 SAR Images: A Case Study of Super Cyclone Amphan

open access: yesJournal of the Civil Engineering Forum, 2021
Floods are triggered by water overflow into drylands from several sources, including rivers, lakes, oceans, or heavy rainfall. Near real-time (NRT) flood mapping plays an important role in taking strategic measures to reduce flood damage after a flood ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

open access: yes, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

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

open access: yesThe 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 ...
