Translational regulation contributes to the elevated CO2 response in two Solanum species. [PDF]

open access: yes, 2020
Understanding the impact of elevated CO2 (eCO2 ) in global agriculture is important given climate change projections. Breeding climate-resilient crops depends on genetic variation within naturally varying populations.

Applications of ascorbic acid or proline increase resistance to salt stress in barley seedlings

open access: yesBiologia Plantarum, 2014
The present study was carried out to examine the effects of seed soaking in 1 mM ascorbic acid (AA) or 1 mM proline on the growth, content of photosynthetic pigments and proline, relative water content, electrolyte leakage, antioxidant enzymes and leaf ...

Leaf Functional Anatomy in Relation to Photosynthesis [PDF]

open access: yesPlant Physiology, 2010
Rubisco is a large enzyme with a molecular mass of approximately 550 kD. The maximum rate of CO2 fixation (i.e. ribulose-1,5-bisphosphate [RuBP] carboxylation) at CO2 saturation is only 15 to 30 mol CO2 mol−1 Rubisco protein s−1 at 25°C.

Pengaruh Kekeringan Terhadap Pertumbuhan Dan Perkembangan Tanaman Nyamplung (Callophylum Inophyllum L.) Dan Johar (Cassia Florida Vahl.) Dari Provenan Yang Berbeda [PDF]

open access: yes, 2017
Nyamplung (Callophylum inophyllum L.) and johar (Cassia florida Vahl.) are alternative plants that are resistant to drought. Global warming that occurred in the last few years caused extreme climate change, one of which is drought.

Scorzonera sensu lato (Asteraceae, Cichorieae) – taxonomic reassessment in the light of new molecular phylogenetic and carpological analyses [PDF]

open access: yes, 2020
Scorzonera comprises 180–190 species and belongs to the subtribe Scorzonerinae. Its circumscription has long been the subject of debate and available molecular phylogenetic analyses affirmed the polyphyly of Scorzonera in its wide sense.

Increasing atmospheric CO2 and canopy temperature induces anatomical and physiological changes in leaves of the C4 forage species Panicum maximum.

open access: yesPLoS ONE, 2019
Changes in leaf anatomy and ultrastructure are associated with physiological performance in the context of plant adaptations to climate change. In this study, we investigated the isolated and combined effects of elevated atmospheric CO2 concentration ...

Leaf anatomy of the South African Danthonieae (Poaceae). IV. Merxmuellera drakensbergensis and M. stereophylla

open access: yesBothalia: African Biodiversity & Conservation, 1981
The leaf blade anatomy of  Merxmuellera drakensbergensis (Schweick.) Conert and  M. stereophylla (J. G. Anders.) Conert is described and illustrated. These two closely related species have virtually identical leaf anatomy—both the leaf in section and the

Leaf physiological and structural plasticity of two Asplenium (Aspleniaceae) species coexisting in sun and shade conditions [PDF]

open access: yesPlant Ecology and Evolution, 2019
Background and aims – Relatively few studies have addressed the sun-shade response of fern species. Moreover, there is no information on species-specific plasticity patterns of such response, their relationship with species ecological requirements and ...
