Exogenous miRNAs induce post-transcriptional gene silencing in plants (Nature Plants)

Small RNAs (sRNAs) are 21- to 24-nucleotide non-coding RNAs that induce gene silencing by targeting specific mRNAs for degradation. They regulate a plethora of developmental and physiological processes. Based on their biogenesis they are classified into two groups: micro-RNAs (miRNAs) and siRNAs. Within a plant, sRNAs act locally or over long distances by moving throughout […]

Large-scale whole-genome resequencing unravels the domestication history of Cannabis sativa (Science Advances)

Throughout history, many cultures have exploited the properties of Cannabis sativa, either as a source of fiber extracts (hemp) or as a medicinal and recreational drug (drug type). It is thought that cannabis was originally cultivated in Asia from where it spread to other regions around the globe, and it was during this process that […]

Cuscuta australis (dodder) parasite eavesdrops on the host plants’ FT signals to flower (PNAS)

Plants sense environmental cues, such as day length, to induce flowering and successfully reproduce. An important mobile regulator of flowering is FLOWERING LOCUS T (FT). Upon floral induction, FT is transported from the leaves to the shoot apical meristem where it triggers flower development. Dodders are root- and leafless plants that parasitize autotrophic plants through […]

Alpine plant growth and reproduction dynamics in a warmer world (New Phytol.)

Climate warming affects plant performance in warm and dry regions. In cold regions, warming stimulates growth and reproduction, but its effects can vary depending on location and species. Whether herbaceous plants can adapt to increasing temperatures is unclear and a matter of concern. In this study Dolezal et al. investigated the effects of climate warming […]
