Most angiosperms are hermaphrodites and produce flowers that have both male (stamens / sperm) and female (carpels / egg) parts. Pannell reviews the developmental and genetic programs that lead to these “perfect” flowers, as well as those that underlie reproductive structure development in dioecious…

The range of responses an individual could display is a contribution of the inheritance of gene variants that determine such responses and the environments experienced by the individual itself and prior generations (nongenetic inheritance). In this review, we discuss recent empirical data to help us…

Plant hormones are active at very small quantities and often act differently in different cell types. Various methods, primarily involving mass spectrometry and sensors, have been developed to identify and quantify hormones with cellular-level precision. Novák et al. review these methods and discuss…

Review: Methods of cell-specific hormone analysis ($) Plant hormones are active at very small quantities and often act differently in different cell types. Various methods, primarily involving mass spectrometry and sensors, have been developed to identify and quantify hormones with cellular-level…

Wednesday, 15 March 2017 Source: University of Western Australia A 60-year-old mystery has been solved by biochemists at The University of Western Australia investigating the origin of a type of digestion-inhibiting proteins thought only to exist in two plant families that contain the important…

This Update focuses on the starch that accumulates in the guard cells that control stomatal pore size and thus the exchange of water vapor, CO2 and O2 between the leaf and the atmosphere. Transitory starch in these cells plays a key role in determining the velocity of stomatal opening in the light. This…
