Environmental influences on kelp performance across the reproductive period: an ecological trade-off between gametophyte survival and growth? [PDF]
PLoS ONE, 2013 Most kelps (order Laminariales) exhibit distinct temporal patterns in zoospore production, gametogenesis and gametophyte reproduction. Natural fluctuations in ambient environmental conditions influence the intrinsic characteristics of gametes, which ...

Reproduction Multitasking: The Male Gametophyte
Annual Review of Plant Biology, 2021 The gametophyte represents the sexual phase in the alternation of generations in plants; the other, nonsexual phase is the sporophyte. Here, we review the evolutionary origins of the male gametophyte among land plants and, in particular, its ontogenesis in flowering plants.

PLoS ONE, 2012 BackgroundThere is a heteromorphic alternative life in the brown seaweed, Saccharina japonica (Aresch.) C. E. Lane, C. Mayes et G. W. Saunders ( = Laminaria japonica Aresch.), with macroscopic monoecious sporophytes and microscopic diecious gametophytes.

Identification of Gametophytic Mutations Affecting Female Gametophyte Development inArabidopsis
Developmental Biology, 1998 The female gametophyte (embryo sac or megagametophyte) plays a critical role in sexual reproduction of angiosperms. It is the structure that produces the egg cell and central cell which, following fertilization, give rise to the seed's embryo and endosperm, respectively.

A new protocol for psychrometric pressure–volume curves of fern gametophytes
Applications in Plant Sciences, 2019 Premise Pressure–volume curves are a widely used analytical framework to derive several key physiological traits related to plant–water relations, including a species’ turgor loss point, osmotic potential at full turgor, and the elasticity of cell walls.

Subcellular distribution of glutathione in the gametophyte [PDF]
Plant Signaling & Behavior, 2011 Glutathione is an important antioxidant and redox buffer in plants. Despite its crucial roles in plant metabolism and defense in the sporophyte, its roles in the gametophyte are largely unexplored. Recently, we demonstrated that glutathione synthesis is essential for pollen germination in vitro.

Scientific Reports, 2023 Cryopreservation is an important technique used in the conservation of various plant tissues. This study proposes a cryopreservation method for the long-term conservation of eastern bracken fern gametophytes (Pteridium aquilinum var.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes. [PDF]
New PhytolKinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

PLANTS, PEOPLE, PLANET, EarlyView.Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

PLANTS, PEOPLE, PLANET, EarlyView.Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...
