Optimal light regime for the cultivation of transgenic Laminaria japonica gametophytes in a bubble-column bioreactor

open access: yes, 2005
Fluctuating light intensity had a more significant impact on growth of gametophytes of transgenic Laminaria japonica in a 2500 ml bubble-column bioreactor than constant light intensity.

Preliminary study documents variable accuracy and inclusion among biology instructor gender/sex definitions

open access: yesNatural Sciences Education, Volume 55, Issue 2, December 2026.
Abstract Society generally presents sex inaccurately as a binary variable based on one or few trait(s), causing myriad issues, including the pursuit of reductionist biology experiments, the creation of laws that limit the rights of women, people with queer genders, and intersex folks, and greater student endorsement of gender stereotypes in ...

Control of Male Gametophyte Development [PDF]

open access: yesTHE PLANT CELL ONLINE, 2004
In a previous review of male gametophyte development ([McCormick, 1993][1]), it was noted that the two areas posed by [Mascarenhas (1975)][2] as fruitful areas for future research were the following.

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.
The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

A review of protocols for the experimental release of kelp (Laminariales) zoospores

open access: yesEcology and Evolution, 2019
Kelps (order Laminariales) are foundation species in temperate and arctic seas globally, but they are in decline in many places. Laminarian kelp have an alternation of generations and this poses challenges for experimental studies due to the difficulties

Developmental genetics of gametophytic apomixis

open access: yesTrends in Genetics, 2001
Some higher plants reproduce asexually by apomixis, a natural way of cloning through seeds. Apomictic plants produce progeny that are an exact genetic replica of the mother plant. The replication is achieved through changes in the female reproductive pathway such that female gametes develop without meiosis and embryos develop without fertilization ...

Evolution in arid environments: the role of betalains, succulence, and medullary bundles

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1250-1268, November 2026.
Overview of the study system. Summary The flowering plant clade Caryophyllales includes many succulent species that grow in drought conditions. Many Caryophyllales species also have betalain pigmentation and medullary bundles, both of which have been linked to stress tolerance, albeit with less precise functional characterisation.
