ABSTRACT
The young prothallus of Polypodium lepidotrichum (Fée) Maxon is a short filament with four to five cells. Later on, the thallus is spathulate. The mature thallus, about eight weeks after germination, is cordate, reniform or ovate with a narrow base. Bisexual and unisexual gametophytes were produced. sporophytes were observed twelve weeks after the spore were sown. It is concluded that the reproductive strategies of P. lepidotrichum include intragametophytic intergametophytic fertilization.

    Callose plays an important role in pollen development in flowering plants. In rice, 10 genes encoding putative callose synthases have been identified; however, none of them has been functionally characterized. In this study, a rice Glucan Synthase-Like 5 (GSL5) knock-out mutant was isolated that...

    Spore germination and the development of the mature prothallia of Thelypteris rhachiflexuosa Riba follow the general pattern described elsewhere for other species of the genus; the germination is ofVittaria-type and the development of prothallia is of Drynaria-type. There is an early...

    The development of the gametophytes of Thelypteris patens (Swartz) Small and Thelypteris puberula (Baker) Morton var. puberula is described in this paper. In both species the laminar, bidimensional stage follows a brief filamentous stage, which has a few cells. The adult prothallia are reniform...

    The article discusses the occurrence of Serpocaulon lasiopus in Mesoamerica. In Flora Mesoamericana, Serpocaulon lasiopus falls within Polypodium loriceum Group 2, which is distinctive by long-creeping rhizomes that bear partially or entirely clathrate, brownish or blackish scales. The stems of...

    Although the behavioral plasticity of flower traits has received considerable attention, its adaptive value is not thoroughly understood. We experimentally examined flower opening/closure in field bindweed (Convolvulus arvensis), a species with short flower persistence (1 day) in which adaptive...

    The spontaneous mutants with genetic male sterility often appear in the breeding nurseries. By selective manipulation the special lines of motherboards can be created; they have the genetic male sterility and a marker sign at the stage of seedlings. These lines are used to produce hybrid seeds...

    Pollination and soil fertility are important ecosystem services to agriculture but their relative roles and potential interactions are poorly understood. We explored the combined effects of pollination and soil fertility in sunflower using soils from a trial characterized by different long-term...
