Use of timelapse photography to determine flower opening time and pattern in banana (Musa spp.) for efficient hand pollination

Scientific Reports, 2021
Sterility and low seed set in bananas is the main challenge to their conventional genetic improvement. The first step to seed set in a banana breeding program depends on pollination at the right time to ensure effective fertilization. This study aimed at

Studies in the Ericoideae (Ericaceae). XV. The generic relationship between Erica and Ericinella

Bothalia: African Biodiversity & Conservation, 1994
The small African genus Ericinella Klotzsch, with one species in Malawi and SW Tanzania and three in the Eastern Cape is shown to exhibit variability in its delimiting characters that overlap with those of Blaeria L. and Philippia Klotzsch, both of which

A Conserved Mechanism of Bract Suppression in the Grass Family   [PDF]

The Plant Cell, 2010
AbstractSuppression of inflorescence leaf, or bract, growth has evolved multiple times in diverse angiosperm lineages, including the Poaceae and Brassicaceae. Studies of Arabidopsis thaliana mutants have revealed several genes involved in bract suppression, but it is not known if these genes play a similar role in other plants with suppressed bracts ...

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

American Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.
