Role of miRNAs in Legume Crops in Response to Biotic and Abiotic Stress
Journal of Pure and Applied Microbiology, 2017 Legumes are special group of nitrogen-fixing plants that are an essential component of cropping system and important source of food/feed for human/animal consumption.

The Influence of Taxonomy and Environment on Leaf Trait Variation Along Tropical Abiotic Gradients
Frontiers in Genetics, 2020 Deconstructing functional trait variation and co-variation across a wide range of environmental conditions is necessary to increase the mechanistic understanding of community assembly processes and improve current parameterization of dynamic vegetation ...

A Complex Systems Approach to Exoplanet Atmospheric Chemistry: New Prospects for Ruling Out the Possibility of Alien Life-As-We-Know-It [PDF]
arXiv, 2023 The near-term capability to characterize terrestrial exoplanet atmospheres may bring us closer to discovering alien life through atmospheric data. However, remotely detectable candidate biosignature gases are subject to false positive signals because they can also be produced abiotically, raising a critical need to develop methods to determine whether ...

Stability of organic molecules against shocks in the young Solar nebula [PDF]
, 2008 One of the fundamental astrobiology questions is how life has formed in our Solar System. In this context the formation and stability of abiotic organic molecules such as CH4, formic acid and amino acids, is important for understanding how organic material has formed and survived shocks and energetic particle impact from winds in the early Solar System.

Implications of Abiotic Oxygen Buildup for Earth-like Complex Life [PDF]
The Astronomical Journal, Vol. 159, No. 4, 144 (2020), 2020 One of the chief paradoxes of molecular oxygen (O$_2$) is that it is an essential requirement for multicellular eukaryotes on Earth while simultaneously posing a threat to their survival via the formation of reactive oxygen species. In this paper, the constraints imposed by O$_2$ on Earth-like complex life are invoked to explore whether worlds with ...

The C2H2 zinc finger protein TaZFP13D increases drought stress tolerance in wheat
Plant Stress, 2022 Wheat is one of the most cultivated crops, and its production is greatly affected by abiotic stresses such as drought. Transcription factors that regulate multiple downstream genes have a good potential to improve stress tolerance due to their ability to

Large ecosystems in transition: bifurcations and mass extinction [PDF]
Ecological Complexity, 2017, 2014 We propose a model of multispecies populations surviving on distributed resources. System dynamics are investigated under changes in abiotic factors such as the climate, as parameterized through environmental temperature. In particular, we introduce a feedback between species abundances and resources via abiotic factors.

Fish larvae from the upper Paraná River: do abiotic factors affect larval density?
Neotropical IchthyologyThe purpose of this study was to evaluate the role of abiotic factors on fish larvae occurrence. Samplings were carried out monthly at 12 stations (grouped in four areas) in the Amambaí, Ivaí and Paraná rivers and in the Itaipu Reservoir (upper Paraná ...
