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.

The Gametophyte-Sporophyte Junction in Land Plants

open access: yes, 1993
The chapter presents a comparative analysis of the placenta in land plants. The gametophyte–sporophyte junction is termed as the placental region. Systematic survey of bryophytes, pteridophytes, and placental analogues in seed plants are also explained ...

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.

THE FEMALE GAMETOPHYTE: DEVELOPMENT AND FUNCTION [PDF]

open access: yes, 2013
The plant life cycle alternates the diploid sporophyte and the haploid gametophyte. The female gametophyte of flowering plants develops within the ovule, a specialized structure within the ovary, which gives rise to the seed after fertilization. Sexual

Regulation of Environmental Factors and Functional Activity of Efficient MAAs Biosynthesis in Undaria pinnatifida Gametophytes

open access: yesShipin gongye ke-ji
To establish a sustainable vegetative propagation system for U. pinnatifida gametophytes and enhance mycosporine–likeamino acids (MAAs) accumulation, this study systematically investigated the effects of key culture conditions—such as light quality ...

Oak masting under climate change: when spatially heterogeneous shifts in flowering phenology reshape pollen limitation

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1314-1326, November 2026.
Conceptual framework illustrating the pollen variables and the hypotheses linking trajectories of pollen phenology and masting. Summary Masting, the irregular, synchronised production of seeds within tree populations, drives forest regeneration and ecosystem dynamics.

Cuticular Waxes in Altered Environments and Their Role in Leaf Water Loss Dynamics

open access: yesPlant, Cell &Environment, Volume 49, Issue 11, Page 8014-8033, November 2026.
ABSTRACT Cuticular waxes undeniably form the primary barrier restricting uncontrolled water loss from leaves, yet the functional consequences of environmentally induced wax modifications for residual (cuticular) transpiration remain a matter of debate. This review summarises current knowledge on how major abiotic stimuli influence foliar cuticular wax ...

A subunit of the oligosaccharyltransferase complex is required for interspecific gametophyte recognition in Arabidopsis [PDF]

open access: yes, 2016
Species-specific gamete recognition is a key premise to ensure reproductive success and the maintenance of species boundaries. During plant pollen tube (PT) reception, gametophyte interactions likely allow the species-specific recognition of signals from

Impacts of Coastal Infrastructure Upgrades on the Endangered Marine Alga Nereia lophocladia

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 10, October 2026.
ABSTRACT Coastal protection infrastructure is routinely upgraded to address structural degradation and rising sea levels. Such work can have unintended ecological impacts depending on the habitats and species involved, as well as the environmental mitigations undertaken.
