Three ancient hormonal cues coordinate shoot branching in a moss

Speaker : Yoan Coudert From department of plant science in University of Cambridge Monday the 7th of april in room 227 at 13.30. Abstract : The evolution of branching underpinned the successful colonization of land by plants. Whereas the shape of early land plants was limited by their apical dichotomous mode of branching, the independent evolution of a lateral …

Adding a dimension to embryogenesys: the role of auxin in cell division

Speaker : Pierre Barbier de Reuille

From Institute of plant sciences, University of Bern

Date and place : 13-02-2014 at 16.00, IBC, room 127

Formative cell divisions are critical for multi-cellular patterning. In plants, in the absence of cell movement, such division follows from placing and orienting the division plane. A major unanswered question is …

Jean Peyhardi defended his thesis December 9, 2013 at University of Montpellier 2.

Title: A new generalized linear model (GLM) framework for analysing categorical data; application to plant structure and development.

Abstract: This thesis proposes a new class of GLMs for a hierarchically-structured categorical response variable such as a partially-ordered variable for instance. We first introduce a new specification of GLM for ordinal or nominal response variable based …
