Construction and Application of an Evaluation Index System for High-Ttemperature Tolerance in Saccharina japonica Gametophytes [PDF]

open access: yesProgress in Fishery Sciences
Saccharina japonica is an economically important alga in China, which was originally derived from wild populations in Japan. Owing to the environmental temperatures in the Chinese cultivation sites being higher than those in its native habitat, heat ...

Adaptation and Acclimation of Gametophytic Traits to Heat Stress in a Widely Distributed Wild Plant Along a Steep Climatic Gradient

open access: yesEcology and Evolution
Climate change‐induced heat waves often reduce seed yields and quality via high‐temperature effects in the gametophytic phase. Yet, in contrast to model and crop species, the ability of pollen and ovules to adapt or acclimate to heat stress in wild ...

Jasmonic acid induces changes in growth and polypeptide composition of fern gametophytes [PDF]

open access: yes, 2001
We studied morphology of gametophytes of the fern Platycerium bifurcation 20 to 45 days after spore sowing. In addition, we examined the effects of 0.01, 0.1, 1, 10 or 100 μM jasmonic acid (JA) on their growth and polypeptide composition.
