Journal of Applied Entomology, EarlyView.ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Pollen tubes growth in almond flowers
California Agriculture, 1975 A two-year study indicated that, under orchard conditions, it takes 96 to 120 hours for pollen tubes to grow through the styles of almond flowers. In view of a rapid decline in receptivity, probably the result of embryo sac degeneration, it is assumed that the sooner the flower is cross-pollinated after opening, the greater the chance of fertilization ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
Journal of Integrative Plant Biology, EarlyView.The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

THESEUS1 is a component of the receptor complex for establishing polytubey block in Arabidopsis
Journal of Integrative Plant Biology, EarlyView.THESEUS1 (THE1) is a component of the CrRLK1L‐RALF signaling complex specifically responsible for establishing the polytubey block at the Arabidopsis septum. Genetic and biochemical analyses demonstrate that THE1, together with FERONIA, ANJ and HERK1, forms a receptor complex that senses pollen tube‐derived RALF peptides, thereby establishing a barrier

Journal of Integrative Plant Biology, EarlyView.The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?
New Phytologist, EarlyView.Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
