Entanglement of plant immunity and endomembrane trafficking revealed by plant-powdery mildew fungal interactions. [PDF]
Summary Plant immunity is complex, and studies of leaf epidermal cells attacked by powdery mildew fungi have been instrumental in revealing how it relies on plant endomembrane trafficking. Immunity against these biotrophic fungi is manifested as cell wall deposits (‘papillae’) and the hypersensitive reaction (HR), both involving plant endomembrane ...

Callose is a plant cell wall polysaccharide whose deposition is spatiotemporally regulated in various developmental processes and environmental stress responses. The appearance of callose in premeiotic anthers is a prominent histological hallmark for the

Callose synthase (CalS5) is required for exine formation during microgametogenesis and for pollen viability in Arabidopsis [PDF]
SummaryCallose (β‐1,3‐glucan) is produced at different locations in response to biotic and abiotic cues. Arabidopsis contains 12 genes encoding callose synthase (CalS). We demonstrate that one of these genes, CalS5, encodes a callose synthase which is responsible for the synthesis of callose deposited at the primary cell wall of meiocytes, tetrads and ...

A plant NLR receptor activates auxin signaling through Aux/IAAs-ARF19 and YUC8-TIR1/AFBs to promote callose-mediated antiviral defense. [PDF]
Phytohormone signaling pathways are crucial for defense against pathogens mediated by pattern recognition receptors and nucleotide-binding leucine-rich repeat (NLR) immune receptors.

Developmental evolution of flowering plant pollen tube cell walls: callose synthase (
Background A number of innovations underlie the origin of rapid reproductive cycles in angiosperms. A critical early step involved the modification of an ancestrally short and slow-growing pollen tube for faster and longer distance transport of sperm to ...

Genome-wide analysis of the CalS gene family in cotton reveals their potential roles in fiber development and responses to stress [PDF]
Callose deposition occurs during plant growth and development, as well as when plants are under biotic and abiotic stress. Callose synthase is a key enzyme for the synthesis of callose.

Exocyst Subunit EXO70H4 Has a Specific Role in Callose Synthase Secretion and Silica Accumulation1[OPEN] [PDF]
Biogenesis of the plant secondary cell wall involves many important aspects, such as phenolic compound deposition and often silica encrustation. Previously, we demonstrated the importance of the exocyst subunit EXO70H4 for biogenesis of the trichome secondary cell wall, namely for deposition of the autofluorescent and callose-rich cell wall layer. Here,

CalS7 encodes a callose synthase responsible for callose deposition in the phloem [PDF]
Summary It has been known for more than a century that sieve plates in the phloem in plants contain callose, a β‐1,3‐glucan. However, the genes responsible for callose deposition in this subcellular location have not been identified. In this paper we examine callose deposition patterns in T‐DNA insertion mutants (
