Haustorial Hairs Are Specialized Root Hairs That Support Parasitism in the Facultative Parasitic Plant Phtheirospermum japonicum.
A haustorium is the unique organ that invades host tissues and establishes vascular connections. Haustorium formation is a key event in parasitism, but its underlying molecular basis is largely unknown. Here, we use Phtheirospermum japonicum, a facultative root parasite in the Orobanchaceae, as a model parasitic plant. We performed a forward genetic screen to identify mutants with altered haust...
متن کاملThe structure of spider’s web fast escaping sets
Building on recent work by Rippon and Stallard, we explore the intricate structure of the spider’s web fast escaping sets associated with certain transcendental entire functions. Our results are expressed in terms of the components of the complement of the set (the ‘holes’ in the web). We describe the topology of such components and give a characterisation of their possible orbits under iterati...
متن کاملA Sharp Growth Condition for a Fast Escaping Spider’s Web
We show that the fast escaping set A(f) of a transcendental entire function f has a structure known as a spider’s web whenever the maximum modulus of f grows below a certain rate. We give examples of entire functions for which the fast escaping set is not a spider’s web which show that this growth rate is best possible. By our earlier results, these are the first examples for which the escaping...
متن کاملEndoplasmic microtubules configure the subapical cytoplasm and are required for fast growth of Medicago truncatula root hairs.
To investigate the configuration and function of microtubules (MTs) in tip-growing Medicago truncatula root hairs, we used immunocytochemistry or in vivo decoration by a GFP linked to a MT-binding domain. The two approaches gave similar results and allowed the study of MTs during hair development. Cortical MTs (CMTs) are present in all developmental stages. During the transition from bulge to a...
