Microbial activities and foliar uptake of nitrogen in the epiphytic bromeliad Vriesea gigantea.
TLDR
To elucidate the importance of different nitrogenous compounds for the nitrogen (N) nutrition of Vriesea gigantea from the Atlantic Rainforest, Brazil, N transformation processes in tank water as well as foliar uptake rates were estimated by 15N labelling techniques.
Endogenous auxin and cytokinin contents associated with shoot formation in leaves of pineapple cultured in vitro
TLDR
It seems that endogenous iP concentration triggered the induction signal for an organogenic response in pineapple leaf bases, and the rise in iP content required the presence of BA and a-naphthaleneacetic acid (NAA) in the medium, suggesting that endogenous iPod production is regulated in response to these growth regulator uptakes.
CAM Photosynthesis in Bromeliads and Agaves: What Can We Learn from These Plants?
The term Crassulacean Acid Metabolism (CAM) was introduced in the 1940s as a result of observations in Bryophyllum calycinum, a crassulacean plant, which showed prominent diel variations in leaf acid
Nitric Oxide Mediates the Hormonal Control of Crassulacean Acid Metabolism Expression in Young Pineapple Plants1[W][OA]
TLDR
Strong evidence revealed that nitric oxide (NO) may fulfill an important role during CAM signaling in pineapple plants, and tungstate or glutamine inhibition of the NO-generating enzyme nitrate reductase completely blocked NO production during ABA-induced up-regulation of CAM, characterizing this enzyme as responsible for NO synthesis during CAM signaled.
THE IMPORTANCE OF TISSUE CULTURE TECHNIQUE FOR CONSERVATION OF ENDANGERED BRAZILIAN BROMELIADS FROM ATLANTIC RAIN FOREST CANOPY
TLDR
This methodology provided a large number of plants, preserving the genetic diversity of the species and is essential for any replacement program that makes use of micropropagated plants.
Effects of NO3−, NH4+ and urea nutrition on endogenous levels of IAA and four cytokinins in two epiphytic bromeliads
TLDR
It is suggested that urea may be an important source of nitrogen often found inside the tank of V. philippocoburgii, while urea and NH 4 + shifted this ratio in favour of cytokinins, thus apparently inhibiting root development in both species.
Temperature determines the occurrence of CAM or C3 photosynthesis in pineapple plantlets grown in vitro
TLDR
A role for temperature in determining the type of carbon fixation pathway in in vitro grown pineapple plants is clearly indicated, and evidence that ABA and IAA participate in CAM signaling is provided.
In vitro nitrogen nutrition and hormonal pattern in bromeliads
SummaryFour cytokinins (CKs), indole-3-acetic acid (IAA) and its ester and amino conjugates, and abscisic acid (ABA) levels of two bromeliads, Ananas comosus (L.) Merril and Vriesea gigantea
