POLYPLOIDY RULES. "We found that while certain rules may govern gene retention and loss, systems vary in the prevalence of gene silencing vs. homeolog loss, chromosomal change, the presence of a dominant genome (in allopolyploids), and the relative importance of hybridization vs. genome doubling per se." https://lnkd.in/bCmw3Fr View in LinkedIn

"EXTRAFLORAL NECTARIES are nectar-secreting parts of the plant surface other than flowers. These organs are not directly involved in pollination, and can be found on virtually all aboveground plant parts. Plants bearing extrafloral nectaries are widely distributed around the world. About 114 plant families with more than 700 genera and 4000 species of plants, including pteridophytes, gymnosperms and angiosperms, are known to possess extrafloral nectaries to date." https://lnkd.in/ewhdr2N View in LinkedIn

DIFFUSE EFFECT. "Although further tests are needed, it is likely that selection following whole-genome duplication is important in all types of species interaction and that there are circumstances in which polyploidy can enhance the evolvability of interactions with other species." https://lnkd.in/bCmw3Fr View in LinkedIn

UNUSUAL SEX LIFE. "The morphology of angiosperm sex organs (flowers), rather than fitting those of the opposite sex, must generate a lock-and-key fit with the animals that visit them. These visitors do not normally come for sex; instead they are paid for their services, typically by means of sugary nectar or surplus pollen. Plants advertise these rewards with showy displays to assist pollinators in finding them." https://lnkd.in/e97k43F View in LinkedIn
