The LACCASE3/5/12/13 clade mediates seed coat lignin deposition and regulates imbibition and germination

Cell Reports
Summary: The seed coat, a multi-layered protective structure containing lignin, is critical for the survival and germination of seeds. How seed coat lignin is spatiotemporally deposited and, thus, its physiological role remain poorly understood.

Transcriptome analysis of a new peanut seed coat mutant for the physiological regulatory mechanism involved in seed coat cracking and pigmentation

Frontiers in Plant Science, 2016
Seed-coat cracking and undesirable color of seed coat highly affects external appearance and commercial value of peanuts (Arachis hypogaea L.). With an objective to find genetic solution to the above problems, a peanut mutant with cracking and brown ...

Anatomical and micromorphological characteristics of the seed coat of field pea (Pisum sativum L.) genotypes in relation to cracks and damage of seeds [PDF]

Archives of Biological Sciences, 2017
In this paper, we present the morphological characteristics of the seed and micromorphological, anatomical and chemical characteristics of the seed coat of pea (Pisum sativum L.) genotypes, Jezero, Javor and NS Junior. Our aim was to investigate

Semipermeability of Seed Coats [PDF]

Botanical Gazette, 1913
1. The dry seed coats of Xanthium are impermeable to dry alcohol, ether, chloroform, and acetone. Becquerel'S results with the coats of other seeds are confirmed. 2. Evidence of the diffusion of oxygen through absolutely dry seed coats was not obtained. 3.

Physiology of Chatham Island forget-me-not (Myosotidium hortensia) seed : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Science in Seed Science and Technology at Massey University [PDF]

, 2003
Chatham Island forget-me-not (Myosotidium hortensia (Decne) Baillon) is endemic to the Chatham Islands where it is mainly confined to the outer islands. There is speculation that seed of M.

Seed coat thinning during horsegram (Macrotyloma uniflorum) domestication documented through synchrotron tomography of archaeological seeds [PDF]

, 2017
Reduction of seed dormancy mechanisms, allowing for rapid germination after planting, is a recurrent trait in domesticated plants, and can often be linked to changes in seed coat structure, in particular thinning.

Signalling events regulating seed coat development

Biochemical Society Transactions, 2014
The evolution of seeds was a major reason for the rise of angiosperms to ecological dominance. Seeds of angiosperms are composed of three main structures: the embryo, which will give rise to the next generation; the endosperm, a nurturing tissue whose main function is to deliver nutrients from the mother plant to the embryo; and the seed coat (or testa)

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Physical and mechanical properties of hard seed coat on the example of Gleditsia triacanthos L. [PDF]

Brazilian Journal of Biology
The microhardness of individual morphological structures of the hard coat of the seed of Gleditsia triacanthos L. was measured. Measurements were made on the transverse and frontal planes.
