Progeny Differentiation in Faba Bean Using Hyperspectral Images and Machine Learning
Plant Direct, Volume 10, Issue 10, October 2026.ABSTRACT Though currently a minor crop, faba bean is a promising source of plant‐based protein as global diets shift towards more plant‐based nutrition. To realize this potential, advances in breeding and cultivation are crucial. To exploit heterosis, faba bean breeding frequently utilizes synthetic cultivars, produced by open pollination of inbred ...

Pest Management Science, Volume 82, Issue 10, Page 9538-9552, October 2026.Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

TAXON, Volume 75, Issue 5, October 2026.Abstract The more than 360 species of stem‐succulent stapeliads in the tribe Ceropegieae represent a perfect example for species radiation and diversification in response to pollination by flies. In the majority of species, the myiophilous flowers have visual and olfactory characteristics that suggest carrion or dung mimicry.

Can the Carbon Storage Function of a Degraded Mountain Wet Meadow Be Restored?
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.Abstract Sierra Nevada meadows experienced intense livestock grazing in the 19th century, resulting in a shift from deep‐rooted highly productive perennial clonal sedges to short‐lived and shallow‐rooted plants. The current meadow vegetation contains >20% bare ground and <10% cover of highly productive clonal sedges and rushes. We hypothesized that the

New Phytologist, 1989 summaryThis review considers pollen tube growth with regard to current information on pollen tube cytoplasm, wall structure and calcium ion interactions with pollen tubes. Pollen tubes have a marked cytoplasmic Polarity with a number of distinct zones along the tube, each with a characteristic complement of cytoplasmic and nuclear structures.

POLLEN GERMINATION AND TUBE GROWTH
Annual Review of Plant Biology, 1997▪ Abstract Many aspects of Angiosperm pollen germination and tube growth are discussed including mechanisms of dehydration and rehydration, in vitro germination, pollen coat compounds, the dynamic involvement of cytoskeletal elements (actin, microtubules), calcium ion fluxes, extracellular matrix elements (stylar arabinogalactan proteins), and control

Protoplasma, 2001
Actin microfilaments (MFs) are essential for the growth of the pollen tube. Although it is well known that MFs, together with myosin, deliver the vesicles required for cell elongation, it is becoming evident that the polymerization of new actin MFs, in a process that is independent of actomyosin-dependent vesicle translocation, is also necessary for ...

Pollen mitosis and pollen tube growth inhibition by SO2 in cultured pollen tubes of Tradescantia
Environmental Research, 1976Abstract Mature pollen of Tradescantia paludosa Anders. Sax clone-3 was collected from greenhouse grown plants and desiccated in the dark for 4–5 hours. The pollen was sown on microslides coated with lactose agar medium (supplemented with 0.02% colchicine).

Cell mechanics of pollen tube growth
Current Opinion in Genetics & Development, 2018The pollen tube features particular traits that can only be understood when integrating cell biological with cell mechanical concepts. Firstly, regular temporal variations in the growth rate are governed by a feedback mechanism thought to involve mechanosensitive ion channels. Secondly, the tube uses invasive growth to penetrate the flower tissues with

Pollen Germination and Pollen Tube Growth
2001Pollen, the male gametophyte of higher plants, is a biological system playing a central role in sexual plant reproduction (Cresti et al., 1992). The understanding of the mechanisms controlling the various aspects of pollen tube development has a direct relevance to biotechnological applications since it represents a starting point to modify crop ...
