Abstract:
... To evaluate the role of ethylene in cold acclimation and cold stress, freezing tolerance and characteristics associated with cold acclimation were investigated using legume model plant Medicago truncatula Gaertn Jemalong A17. There was a rapid suppression of ethylene production during cold acclimation in A17 plants. Ethylene level was negatively correlated with freezing tolerance as inhibition of ...

Abstract:
... Regulation of stomatal (gₛ) and mesophyll conductance (gₘ) is an efficient means for optimizing the relationship between water loss and carbon uptake in plants. We assessed water‐use efficiency (WUE)‐based drought adaptation strategies with respect to mesophyll conductance of different functional plant groups of the forest understory. Moreover we aimed at assessing the mechanisms of and interactio ...

Abstract:
... Maritime pine somatic embryos (SEs) require a reduction in water availability (high gellan gum concentration in the maturation medium) to reach the cotyledonary stage. This key switch, reported specifically for pine species, is not yet well understood. To facilitate the use of somatic embryogenesis for mass propagation of conifers, we need a better understanding of embryo development. Comparison o ...

Abstract:
... ETHYLMALONIC ENCEPHALOPATHY PROTEIN 1 (ETHE1) encodes sulfur dioxygenase (SDO) activity regulating sulfide levels in living organisms. It is an essential gene and mutations in ETHE1 leads to ethylmalonic encephalopathy (EE) in humans and embryo lethality in Arabidopsis. At present, very little is known regarding the role of ETHE1 beyond the context of EE and almost nothing is known about factors a ...

Abstract:
... The non‐specific lipid transfer proteins (nsLTPs) constitute a large protein family specific for plants. Proteins from the family are found in all land plants but have not been identified in green algae. Their in vivo functions are still disputed although evidence is accumulating for a role of these proteins in cuticle development. In a previous study, we performed a co‐expression analysis of glyc ...

Abstract:
... Allantoate degradation is an essential step for recycling purine‐ring nitrogen in all plants, but especially in tropical legumes where the ureides allantoate and allantoin are the main compounds used to store and transport the nitrogen fixed in nodules. Two enzymes, allantoate amidohydrolase (AAH) and allantoate amidinohydrolase (allantoicase), could catalyze allantoate breakdown, although only AA ...

Abstract:
... Oxylipins produced by the 13‐lipoxygenase (LOX) have been reported to play an important role in plant defense responses to herbivores. Yet, the role of oxylipins produced by the 9‐LOX pathway in this process remains largely unknown. Here we cloned a gene encoding a chloroplast‐localized 9‐LOX, Osr9‐LOX1, from rice. Transcriptional analysis revealed that herbivore infestation, mechanical wounding a ...

Abstract:
... Symphyotrichum ericoides was shown earlier to contain hyperaccumulator levels of selenium (Se) in the field (>1000 mg kg⁻¹ dry weight (DW)), but only when growing next to other Se hyperaccumulators. It was also twofold larger next to hyperaccumulators and suffered less herbivory. This raised two questions: whether S. ericoides is capable of hyperaccumulation without neighbor assistance, and whethe ...

Abstract:
... Plant roots under nitrogen deficient conditions with access to both ammonium and nitrate ions, will take up ammonium first. This preference for ammonium rather than nitrate emphasizes the importance of ammonium assimilation machinery in roots. Glutamine synthetase (GS) and glutamate synthase (GOGAT) catalyze the conversion of ammonium and 2‐oxoglutarate to glutamine and glutamate. Higher plants ha ...

The canopy consists of three tiller types, of which the stem forming vegetative elongating (ELONG) tiller and generative (GEN) tillers contribute the most to dry matter yield. In this study, the regulation of tiller formation by vernalization, day length (DL) [12 h, short day length (SD); 16 h, long day length ...

Recalcitrance of plant biomass is closely related to the presence of the phenolic heteropolymer lignin in secondary cell walls, which has a negative effect on forage digestibility, biomass‐to‐biofuels conversion and chemical pulping. The genus Eucalyptus is the main source of wood for pulp and paper industry. However, when compared to model plants such as Arabidopsis thaliana and poplar, relativel ...
