Regulatory networks in pollen development under cold stress

Frontiers in Plant Science, 2016
Cold stress modifies anthers’ metabolic pathways to induce pollen sterility. Cold-tolerant plants, unlike the susceptible ones, produce high proportion of viable pollen.

Whole-transcriptome analysis and construction of an anther development-related ceRNA network in Chinese cabbage (Brassica campestris L. ssp. pekinensis)

Scientific Reports, 2022
Anther development is precisely regulated by a complex gene network, which is of great significance to plant breeding. However, the molecular mechanism of anther development in Chinese cabbage is unclear.

Chamaecrista marinasilvae sp. nov. (Leguminosae, Caesalpinioideae): a threatened new species from the deforestation frontier of the Brazilian Cerrado

Nordic Journal of Botany, EarlyView.
During a field expedition to the Jalapão region (Tocantins State, Brazil), a morphologically distinct specimen was collected and identified as a new species, Chamaecrista marinasilvae. Further herbarium investigations revealed additional collections of this taxon from the same state that had been misidentified as Chamaecrista juruenensis.

The role of atmospheric precipitation in anther dehiscence [PDF]

, 2020
Anther dehiscence is an important process taking place at the end of the plant life cycle. This process consists of various follow-up steps which result in anther opening and pollen grains exposure.

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

Occurrence of parietal and invasive tapetum in Dyckia strehliana (Bromeliaceae): first report for the Family [PDF]

Rodriguésia
Tapetal tissue plays essential roles in the formation of generative cells, as it is related to their nutrition and development in anthers. Among the few species of Bromeliaceae for which tapetal tissue has been describe, most have a secretory tapetum and

Multiple barriers maintain species boundaries in sympatric brood‐site deceptive Gastrodia orchids

PLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Gastrodia orchids are inconspicuous forest plants that lack chlorophyll and obtain carbon from fungi. Their dull‐colored, ground‐level flowers are often hidden among leaf litter, yet they rely on small flies for pollination.
