🔥 Fire-stimulated flowering appears to be an adaptive strategy that helps plants maximize reproductive success in fire-prone ecosystems. Fire may play a major role in shaping plant life-history evolution in Mediterranean habitats. (7/7)

Distyly (Evolution 🧬)

Distyly is a breeding system in plants that is characterized by two separate flower morphs, where individual plants produce flowers that have either long styles and short stamens or short styles and long stamens. However, distyly can refer to any plant that shows some degree of self-incompatibility and has two morphs if at least one of the following cha...

Meng Hou et al. took #AconitumGymnandrum as the example, estimated the effects of #FloralDisplaySize, #NectarGradient and their interactions on #PlantReproduction. The results suggest the trade-off between geitonogamy cost and reproductive benefit may play a potential role in evolution of #FloralTraits.

Genetics of Alternating Sexes in Walnuts

Scientists have uncovered a genetic mechanism in walnuts and their ancestors that has remained stable for 40 million years. Male-first or female-first flowering, balanced by a single genetic locus, parallels sex determination in animals. This evolutionary trait ensures genetic diversity, with distinct pathways evolving independently in walnuts and pecans.

Distyly (Evolution 🧬)

Distyly is a type of heterostyly in which a plant demonstrates reciprocal herkogamy. This breeding system is characterized by two separate flower morphs, where individual plants produce flowers that either have long styles and short stamens, or that have short styles and long stamens. However, distyly can refer to any plant that shows some degree of sel...
