Photosynthesis underpins the viability of most ecosystems, with C 4 plants that exhibit ‘ K
ranz’ anatomy being the most efficient primary producers. K ranz anatomy is characterized by …

The extent to which the shoot apical meristem (SAM) controls developmental decisions,
rather than interpreting them, is a longstanding issue in plant development. Previous work …

Highlights • sRNA networks are key regulators of diverse aspects of vegetative growth. •
Increasing evidence suggests multiple developmental roles for certain sRNAs. • The extent of …

Leaves with Kranz anatomy exhibit a highly characteristic arrangement of closely spaced veins
surrounded by concentric wreaths of bundle sheath and mesophyll cells. This anatomical …

Land plant life cycles are separated into distinct haploid gametophyte and diploid sporophyte
stages. Indeterminate apical growth evolved independently in bryophyte (moss, liverwort, …

How organisms control when to transition between different stages of development is a key
question in biology. In plants, epigenetic silencing by Polycomb repressive complex 1 (PRC1…

All the above-ground organs of a plant are derived from stem cells that reside in shoot apical
meristems (SAM). Over the past 25 years, the genetic pathways that control the proliferation …

All grass leaves are strap-shaped with a series of parallel veins running from base to tip, but
the distance between each pair of veins, and the cell-types that develop between them, …

In Arabidopsis, loss of the carboxypeptidase ALTERED MERISTEM PROGRAM1 (AMP1)
produces an increase in the rate of leaf initiation, an enlarged shoot apical meristem and an …

Traffic lines are transgenic stocks of Arabidopsis thaliana that contain a pair of linked seed-specific
eGFP and DsRed markers. These stocks were originally developed for the purpose of …
