Paphiopedilum and Cypripedium are close relatives in the subfamily Cypripedioideae. Cypripedium leaves contain guard cell chloroplasts, whereas Paphiopedilum do not. It is unclear whether the lack of guard cell chloroplasts affects photosynthetic induction, which is important for understory plants to utilize sunflecks. To understand the role of guard cell chloroplasts in photosynthetic induction of Paphiopedilum and Cypripedium, the stomatal anatomy and photosynthetic induction of Paphiopedilum…

Paphiopedilum spp, well-known as lady’s slipper orchids in horticulture, belong to Paphiopedilum genus, Orchidaceae family [6]. With respect to leaf traits, Paphiopedilum has coriaceous, green or

Vegetative anatomy and photosynthetic performance of the only known winter-green Cypripedium species: implications for divergent and convergent evolution of slipper orchids

The long-lived, thin leaves of C. subtropicum represent a distinct adaptive strategy in subfamily Cypripedioideae, shedding light on the divergent and convergent evolution in slipper orchids, and it is hoped these findings will contribute to the conservation of such an endangered orchid.

The Sustainable Reasons of Controversy over the Mechanisms for the Stomatal Opening

It is assumed that guard cell chloroplasts in Lilium longiflorum may play an important role for the stomatal opening, given the distinctive features of guard cells are specialized cell walls, which are considerably thickened to 5 µm.

Guard cell photosynthesis is critical for stomatal turgor production, yet does not directly mediate CO2 - and ABA-induced stomatal closing.

The present findings show that stomatal movement responses to [CO2 ] and ABA are functional in guard cells that lack chlorophyll, and suggest that guard cell CO2 and A BA signal transduction are not directly modulated by guard cell photosynthesis/electron transport.

Differences in the stimulation of cyclic electron flow in two tropical ferns under water stress are related to leaf anatomy.

The results indicate that the stimulation of CEF in tropical ferns contributes to their photoprotection under water stress, and is related to their respective drought tolerance and leaf anatomy.

Evolutionary Association of Stomatal Traits with Leaf Vein Density in Paphiopedilum, Orchidaceae

The hypothesis for correlated evolution between stomatal traits and vein density in Paphiopedilum is supported, but the results do not provide evidence for an evolutionary association betweenStomata and leaf thickness.

Physiological diversity of orchids

De novo assembly and characterization of the root transcriptome and development of simple sequence repeat markers in Paphiopedilum concolor.

This study provides valuable insights into the mechanisms of genes that regulate root growth and development and provides a comprehensive resource for genes related to secondary metabolism in roots and for marker-assisted studies in Paphiopedilum.

Red/blue light ratio strongly affects steady-state photosynthesis, but hardly affects photosynthetic induction in tomato (Solanum lycopersicum).

It is concluded that varying red/blue light ratios during growth and measurement strongly affects steady-state photosynthesis, but has limited effects on photosynthetic induction rate.



Stomatal Limitation to Carbon Gain in Paphiopedilum sp. (Orchidaceae) and Its Reversal by Blue Light.

Blue light enrichment resulted in significantly higher growth rates-of up to 77%-over a 3 to 4 week growing period, with all evidence indicating that the blue light effect was a stomatal response.

Phytochrome and blue light-mediated stomatal opening in the orchid, paphiopedilum.

It is found that low fluence rate green and red light elicited stomatal opening in Paphiopedilum and this opening was reversed by far red light, indicating the presence of a phytochrome-mediated opening response.

Stomatal Responses to CO(2) in Paphiopedilum and Phragmipedium: Role of the Guard Cell Chloroplast.

Investigation of the leaf gas exchange characteristics of two closely related orchids suggests involvement of guard cell chloroplasts in the stomatal response to CO(2) and in the coupling of assimilation and conductance in the intact leaf.


Stomatal opening under red light was indistinguishable from that in darkness, whereas blue light promoted opening above dark levels, suggesting that the previously reported red light responses in stomata from intact Paphiopedilum leaves resulted from indirect effects, such as depletion of intercellular CO2 by mesophyll photosynthesis.

Gas exchange in paphiopedilum: lack of chloroplasts in guard cells correlates with low stomatal conductance.

The genetic changes leading to the loss of chloroplast differentiation in Paphiopedilum guard cells were not deleterious because of the low conductance rates characteristic of this genus, singles them out as an exceptional biological system, exhibiting basic differences from typical stomata in higher plants.

The responses of guard and mesophyll cell photosynthesis to CO2, O2, light, and water stress in a range of species are similar.

The photosynthetic efficiency in guard cells is determined by the same factors that determine it in the mesophyll, and Rubisco activity is significant in the guard cells of these six species.

Ecophysiological significance of leaf traits in Cypripedium and Paphiopedilum.

The results show that the evolution of the leaf traits of Paphiopedilum and Cypripedium are shaped by both phylogeny and environment.

Photosynthetic Induction and Stomatal Oscillations in Relation to the Light Environment of Two Dipterocarp Rain Forest Tree Species

In some circumstances transient peaks in A and ga were observed during induction, rather than a rise to a stable maximum, which is attributed to overcompensation of the stomatal response to light.

Leaf anatomical structures of Paphiopedilum and Cypripedium and their adaptive significance

The present results contribute to the understanding of the divergent adaptation of leaf traits in slipper orchids, which is beneficial for the conservation of endangeredOrchids.

It is suggested that photosynthetic acclimation can influence some aspects of a leaf's dynamic response to sunflecks, such as Amax and induction loss, while not affecting overall induction rates.
