A femtomolar-range suicide germination stimulant for the parasitic plant Striga hermonthica (Science)($)

Striga hermonthica (Striga) parasitizes a wide range of crops including sorghum and rice, mainly  in sub-Saharan Africa. This parasite decreases crop yields and results in billions of dollars in economic damage. Striga seeds are numerous and remain dormant in the soil until prompted to germinate by the presence of host-generated hormones called strigolactones. Application of […]

Review: Long distance signlaing in plant stress response (COPB)

To compensate for their lack of a nervous system, vascular plants have developed complex mechanisms to connect their organs and coordinate stress. Many different types of molecules are involved in long-distance signaling and must be integrated to maintain homeostasis. In this review, Takahashi and Shinozaki explore current knowledge of plant molecules including small proteins, peptides, […]

An unexpected flower from the Jurassic of China (eLIFE)

The economic importance of angiosperms, whether for food, ornamentals, timber, pharmaceuticals, or any other commercial product is easy to prove. However, their origin is not. Evolutionary biologists have long debated the origin of flowering plants. Fu et al., have unearthed fossils from the Early Jurassic period that suggest angiosperms may have been here longer than […]

Primula vulgaris (primrose) genome, and the heterostyly supergene (Sci. Reports)

Floral heteromorphy (differences in form) in Primula has long been of interest to plant biologists. Over 150 years ago, Charles Darwin recognized the importance of this floral anatomy for promoting cross-pollination. In heterostylous Primula species, plants produce either, pin or thrum flowers. Pins have a long style and low anthers, whereas thrums have a short […]

Pivotal roles of cryptochromes 1a and 2 in tomato development and physiology (Plant Phys)

Cryptochromes are a class of flavoproteins found in plants and animals that are sensitive to blue light. In Arabidopsis, cryptochromes are involved in many important physiological processes including de-etiolation, flowering, circadian rhythms, cotyledon opening and expansion, anthocyanin accumulation, and root growth. In economically important crops, these photoreceptors could be manipulated to influence horticultural traits such […]

OsRR24/LEPTO1 type-B response regulator is essential for rice meiosis (Plant Cell)

In rice, successful completion of meiosis to generate haploid cells is essential for seed production and propagation. This process is complex, requires precise regulation, and produces visible changes in the structure of chromosomes. In this paper, Zhao et al., characterize a sterile rice mutant with defects in leptotene, an early stage of prophase I in […]

Plant Science Research Weekly: December 21st

Welcome to the penultimate 2018 collection of plant research highlights. Starting this week, for search engine optimization (SEO) purposes we are renaming the series “Plant Science Research Weekly“. We thank contributors and readers for their ongoing support. We started this project more than two years ago (October 2016) for several reasons. Firstly, as a one-stop-shop […]
