Callose Deposition during Pollen Development [PDF]

Plant Physiology, 2020
Callose is a cell wall component that is dynamically deposited and degraded during pollen development. Thanks to a new article investigating pollen formation in cotton ( Gossypium hirsutum ), we now know that a pollen-specific protein regulates callose deposition by inhibiting the action of ...

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

, 1988
Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several

Proline synthesis in developing microspores is required for pollen development and fertility [PDF]

, 2018
Background: In many plants, the amino acid proline is strongly accumulated in pollen and disruption of proline synthesis caused abortion of microspore development in Arabidopsis.

Higher Temperature at Lower Elevation Sites Fails to Promote Acclimation or Adaptation to Heat Stress During Pollen Germination

Frontiers in Plant Science, 2018
High temperatures associated with climate change are expected to be detrimental for aspects of plant reproduction, such as pollen viability. We hypothesized that (1) higher peak temperatures predicted with climate change would have a minimal effect on ...

Abundance of Insects Inhabiting the Male Strobili of Red Pine [PDF]

, 2017
(excerpt) Southwood (1973) concluded that pollen feeding was probably the first step in the development of the phytophagous habit in insects, because pollen, compared with plant foliage, is rich in nutrients and low in sewndary defense substances ...
