Homeodomain protein underpins leaf shape variation in cotton ($)

Homeodomain transcription factors are well-known as regulators of developmental patterning, including in leaves. Andres et al. examine the molecular basis behind leaf shape in cotton, particularly the Okra locus that was identified by breeders as a regulator of leaf shape. They show that the Okra locus…

Domestication impacts on plant–herbivore interactions: a meta-analysis

It is widely stated that domestication has contributed to a decrease in plant resistance to herbivory, but to what extent is this true? In a contribution to a special issue on “Human influences on evolution”, Whitehead et al. describe results of their meta-analysis. Although their data show a consistent…

Plant-permeable trehalose 6-phosphate analogues increase yield and resilience ($)

Trehalose-6-phosphate (T6P) is a sugar signaling molecule that regulates how plants allocate and use sucrose, which in turn affects stress resilience and yields. Griffiths et al. designed a plant-permeable, photo-activated T6P analogue that is converted to T6P in planta. Spraying this compound onto plants…

Opinion Paper: Bandwagons I, too, have known (reflections of a plant breeder) ($)

In this entertaining Opinion article written for the 150th anniversary of Mendel’s seminal work, Bernardo reviews “bandwagons” that have come and gone in plant breeding. Early bandwagons such as induced polyploidy are discussed, as well as more recent trends such as trangenics, molecular markers…

Gene editing to produce doubly-determinate, early-yielding tomatoes ($)

Tomatoes have an indeterminate growth pattern that arises from the balance of flower-promoting (florigen) and flower repressing activities. Suppressing this flower-repressing activity leads to greater determinacy and facilitates cultivation. Soyk et al. compared flowering times in short- and long-days…

Best of 2016: Top Topics in The Plant Cell journal

We’ve highlighted some of the Plant Cell papers that were widely shared, liked, blogged, retweeted and otherwise garnered high-levels of attention this year. Perhaps you can use some holiday-season quiet time to catch up on those you missed. Reviews and Perspectives Creating order from chaos: epigenome…

The Power of Plasticity in Polyploid Persimmon

IN BRIEF by Jennifer Lockhart jlockhart@aspb.org Most plants are hermaphrodites, producing perfect flowers with both male and female functions. In roughly 6% of plants, however, male (usually XY) plants produce only male flowers and female (XX) plants produce only female flowers. These dioecious plants…

Biofortification of plants: New Reviews ($)

Biofortification is the nutritional enhancement (using conventional or genetic engineering approaches) of food with vitamins or micronutrients with the goal of improving the human diet. A set of new reviews in Current Opinion in Biotechnology summarizes progress towards biofortification of plants to…
