Self-incompatibility (SI) is a mechanism  used by flowering plants to prevent self-fertilization. It is controlled by a multi-allelic S-locus that allows self/non-self-recognition between pistil and pollen. In several SI systems, when male and female S-determinants match, self pollen is recognized and…

Circadian rhythms are ubiquitous among living things. A core set of so-called clock genes and their products assemble an oscillatory network that provides a rhythm to anticipate dawn and dusk (Hsu and Harmer, 2014). The circadian clock regulates the day/night rhythms of plants and light itself has many…

During fruit ripening in tomato and other flowering plants, the seeds contained within the fruit normally become dormant. However, under certain physiological conditions, seeds can germinate within fruits, a phenomenon called vivipary. Vivipary can substantially reduce yield and product quality in vegetables,…

Salt stress is a major abiotic factor restricting crop growth and productivity. Excess sodium (Na+) causes ion toxicity and ion imbalances.  Maintaining lower Na+ accumulation in shoots is crucial for salt tolerant plant species and genotypes under salt stress.  Lower shoot Na+ accumulation in plants…

Extreme temperatures often negatively impact plant productivity. Both heat and cold induce transient Ca2+ influx into the cell cytoplasm. Cui et al. (10.1104/pp.20.00591) have investigated the function of two closely related cyclic nucleotide-gated ion channel (CNGC) proteins, OsCNGC14 and OsCNGC16,…

Pollen tubes elongate very rapidly at rates of several micrometer per minute and strictly in one direction: this process involves the intense local secretion of cell wall material at the tube tip. Consequently, there is a massive incorporation into the plasma membrane (PM) of excess membrane material…
