The genetic architecture of leaf vein density and its importance for photosynthesis in maize

New Phytologist, EarlyView.
Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.

Turnip mosaic virus utilizes the lipid droplet biogenesis machinery to facilitate its propagation in plants

New Phytologist, EarlyView.
Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions, including membrane remodeling during abiotic stress.

Design of Low-Complexity Coded Modulation Employing High-Order QAM With Systematic Geometric Constellation Shaping

IEEE Open Journal of the Communications Society
In this work, we investigate the performance of geometric constellation shaping for highorder coded quadrature amplitude modulation (QAM) over an additive white Gaussian noise (AWGN) channel.

Loss of DET1 in High Pigment 2 Tomato Prevents High Temperature Repression of Anthocyanin Biosynthesis in Fruit Through HY5 Stabilization

Plant, Cell &Environment, EarlyView.
ABSTRACT Global warming impacts several aspects of plant physiology, with important negative effects on crop yield and production of secondary metabolites, such as anthocyanins. The anthocyanin content of vegetables and fruits has attracted public interest in the last two decades due to its health benefits, leading to the development of novel ...

Three-Dimensional EXIT Chart Analysis of Iterative Detection Aided Coded Modulation Schemes

, 2006
The iterative convergence of iteratively detected coded modulation schemes having different block lengths, decoding complexity and an unequal error protection capability is studied, when communicating over AWGNchannels using 8PSK modulation.

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

Plant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and
