Why are the inner and outer sides of many flower petals differently coloured?
Plant Biology, Volume 26, Issue 5, Page 665-674, August 2024.Evolutionary hypotheses aimed at explaining why inner and outer sides of petals are often differently coloured. Abstract The flower perianth has various, non‐mutually exclusive functions, such as visual signalling to pollinators and protecting the reproductive organs from the elements and from florivores, but how different perianth structures and their

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana
Plant Direct, Volume 8, Issue 7, July 2024.Abstract Cytoplasmic projections (CPs) formed by the generative and sperm cells link the male gametes with the vegetative cell (VC) nucleus, which are required to build the male germ unit (MGU) assemblage in the angiosperm pollen grain. As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized

Cytogenetic studies in the Eragrostis curvula Complex
Bothalia: African Biodiversity & Conservation, 1977 Cytogenetic studies were undertaken in the Eragrostis curvula Complex. Three plants were studied at each of 16 collecting points. The overall morphology and embryo sac development of all plants were evaluated, while the chromosome number and ...

Overexpression of the Tomato Pollen Receptor Kinase LePRK1 Rewires Pollen Tube Growth to a Blebbing Mode [PDF]
, 2014 The tubular growth of a pollen tube cell is crucial for the sexual reproduction of flowering plants. LePRK1 is a pollen-specific and plasma membrane–localized receptor-like kinase from tomato (Solanum lycopersicum). LePRK1 interacts with another receptor,

Synteny analysis in Rosids with a walnut physical map reveals slow genome evolution in long-lived woody perennials. [PDF]
, 2015 BackgroundMutations often accompany DNA replication. Since there may be fewer cell cycles per year in the germlines of long-lived than short-lived angiosperms, the genomes of long-lived angiosperms may be diverging more slowly than those of short-lived ...
