An additional observations on protonema of Schistostega pennata (Bryophyta)

Abstract

The protonema of Schistostega pennata is well known due to its specific structure, making it luminous in a cat-eye manner. The growth patterns of protonemata are overviewed, including a filiform type that was not previously described for this species. The latter, however, seems to be important for the species, forming "bridges" between soil pieces and thus building its own habitat. The sticky surface of propaguliferous protonemata is also capable to stabilize surfaces where the species grows. Growth of protonemata is studied both in nature and in cultivation, showing outstanding plasticity and ground-cementing capacity. РезюмеПротонема Schistostega pennata хорошо известна благодаря ее уникальным пластинчатым структурам из линзовидных клеток, благодаря которым она светится наподобие кошачьего глаза. Изучены особенности роста протонемы, включая ее нитевидную форму, которая ранее не была описана. В то же время нитевидная протонема позволяет строить "мосты" между фрагментами субстрата, создавая условия для дальнейшего роста пластинок. Клейкая поверхность выводковых тел протонемы также способствует закреплению субстрата. Рост протонемы изучался как в природе, так и в культуре, что позволило подтвердить ее выдающуюся пластичность и способность "цементировать" поверхности, на которых она растет.

A role for ecophysiology in the ’omics’ era

“…F.Weber & D.Mohr; Figure 2a] can survive and photosynthesize where no other autotrophic plant can, almost at complete darkness in the entrances of caves and holes. This survivability is due to a fantastic adaptation: the protonema (juvenile gametophyte) that has specialized lens-shaped cells that supposedly act to concentrate the fewer photons into the tightly grouped chloroplasts located at the cell's bottom (Ellis and Price, 2012;Ignatov et al, 2012).…”

Living Light 2018: Conference Report

“…Masters followed up with a contribution on the dynamic structural color changes in the brown alga Cystoseira tamariscifolia [10]. Light management in plants was also discussed in the context of the Goblin’s gold moss by Dr. Martin Lopez-Garcia [11].…”
