Seeing the forest with the leaves - clues to canopy placement from leaf fossil size and venation characteristics.

16 Dec 2009 Although a variety of leaf characteristics appear to be induced by light environment during development, analysis of ontogenetic changes in living broad leaved trees has suggested that a number of other traits also lumped into the classic 'sun' ... Read more...

Long-term persistence of a neotropical ant-plant population in the absence of obligate plant-ants.

30 Aug 2009 Interactions between ants and ant-plants are considered classic examples of obligate mutualisms. Previous studies have indicated that for many ant-plants the loss of ant colonies results in severe defoliation or mortality. Although individual plants ... Read more...

Auxin patterns Solanum lycopersicum leaf morphogenesis.

30 Aug 2009 One of the most striking aspects of plant diversity is variation in leaf shape. Much of this diversity is achieved by the modulation of leaf blade dissection to form lobes or leaflets. Here, we show that the phytohormone auxin is a crucial signal ... Read more...
