A nanobionic light emitting plant ($)

Reading books by the light of nanobionic plants sounds like something out of a scifi book. However, scientists have been working for many years on engineering light-emitting plants based on the luciferase enzyme. This work has been limited largely by the need to overcome the toxicity of adding to much…

Increased efficiency of targeted mutagenesis by CRISPR/Cas9 in plants using heat stress ($)

CRISPR/Cas9 genome editing has rapidly become a powerful tool in modern plant science research.  However, issues of low editing efficiencies and off-target mutations remain.  LeBlanc et al. hypothesised that subjecting plants to high temperature stress, mimicking the optimal operating temperature of…

Review. Genomic selection in plant breeding: Methods, models, and perspectives

In future years, climate change may cause significant economic losses to countries worldwide. Consequently, genetic improvement of crops fit for drought-stressed and semi-arid regions is becoming a must. In this review, Crossa et al. assess the advances in genetic selection (GS) and genomic-enabled prediction…

Update: Advances in imaging plant cell dynamics

By Jozef Samaj, George Komis, Dominik Novak, Miroslav Ovecka, Olga Samajova Abstract After the establishment of advanced fluorescence microscopy methods and the development of numerous fluorescent proteins it is possible to follow the organization and dynamics of most organelles and subcellular…

Nitric Oxide and Diatoms

All gases in the N cycle, including nitric oxide (NO), are present in oceans, either because of gas exchanges at the air-water interface or because they are produced within oceans themselves. NO, a physiologically important gaseous transmitter, is generated in seawater by nonbiological photochemical…

A MicroRNA Affecting Grain Yield in Rice

MicroRNAs (miRNAs), a class of abundant small noncoding RNAs, have been identified as important regulators of gene expression in plants, affecting many aspects of plant development. Recently, several miRNAs have been reported to regulate rice grain yield. A previous study revealed that miR397 regulates…

Xylem Sap Surface Tension and Hydraulic Safety

Xylem embolisms are induced by drought stress and/or freezing stress by means of “air-seeding,” that is the aspiration of gaseous bubbles into xylem conduits from adjacent gas-filled compartments via the pits. At water potentials less negative than the threshold for air seeding, the air-water interface…

Chemical Defenses of Maize Roots

Of the many classes of natural products produced by plants, terpenoids are the most structurally diverse, with well over 25,000 established compounds. In maize (Zea mays), terpene olefins are nearly ubiquitous components of induced volatile emissions following biotic stress. In contrast to our understanding…
