Pollen morphology of Acalypha L. (Euphorbiaceae) with emphasis on Brazilian species from Bahia
Acta Botânica Brasílica, 2022 We investigated the pollen morphology of eight species of Acalypha occurring in Bahia State, Brazil. Flower buds were collected from specimens deposited in the CEPEC and HUEFS herbaria.

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]
, 2013 Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.

On some pollen morphological concepts [PDF]
Grana, 1979 Abstract The paper reviews some widely used pollen morphological concepts which are slightly vague and ambiguous. To meet the needs of palynological descriptions, the terminology has to be precise and, as far as possible, numerically defined. The terms oncus, verruca, annulus, prolate and oblate are discussed and redefined.

Pollen morphology of fruit species
International Journal of Horticultural Science, 2000 Size and surface morphology of pollen has been studied in 87 twit varieties of 10 fruit species during the period of 1990-1995. No preceding work of that type came to our knowledge, yet.

Applications in Plant Sciences, EarlyView.Abstract Premise The censer seed dispersal mechanism, whereby mature fruits are retained on plants and seeds dispersed by mechanical shaking, is among the most specialized wind‐aided seed dispersal strategies employed by the flowering plants. An efficient, affordable, and easily repeatable protocol for determining whether a species uses this unusual ...

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

Animal‐mediated seed dispersal: A review of study methods
Applications in Plant Sciences, EarlyView.Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.
