Plant ER geometry and dynamics: biophysical and cytoskeletal control during growth and biotic response.

This is the author accepted manuscript. The final version is available from Springer via the DOI in this record.The endoplasmic reticulum (ER) is an intricate and dynamic network of membrane tubules and cisternae. In plant cells, the ER 'web' pervades the cortex and endoplasm and is continuous with adjacent cells as it passes through plasmodesmata. It is therefore the largest membranous organelle in plant cells. It performs essential functions including protein and lipid synthesis, and its morphology and movement are linked to cellular function. An emerging trend is that organelles can no longer be seen as discrete membrane-bound compartments, since they can physically interact and 'communicate' with one another. The ER may form a connecting central role in this process. This review tackles our current understanding and quantification of ER dynamics and how these change under a variety of biotic and developmental cues.IS, RW and CL are funded by a Leverhulme Trust grant (RPG-2015-106) and CP by a Sainsbury studentship.

ER network dynamics are differentially controlled by myosins XI-K, XI-C, XI-E, XI-I, XI-1, and XI-2

This document is protected by copyright and was first published by Frontiers. All rights reserved. It is reproduced with permission.The endoplasmic reticulum (ER) of higher plants is a complex network of tubules and cisternae. Some of the tubules and cisternae are relatively persistent, while others are dynamically moving and remodeling through growth and shrinkage, cycles of tubule elongation and retraction, and cisternal expansion and diminution. Previous work showed that transient expression in tobacco leaves of the motor-less, truncated tail of myosin XI-K increases the relative area of both persistent cisternae and tubules in the ER. Likewise, transient expression of XI-K tail diminishes the movement of organelles such as Golgi and peroxisomes. To examine whether other class XI myosins are involved in the remodeling and movement of the ER, other myosin XIs implicated in organelle movement, XI-1 (MYA1),XI-2 (MYA2), XI-C, XI-E, XI-I, and one not, XI-A, were expressed as motor-less tail constructs and their effect on ER persistent structures determined. Here, we indicate a differential effect on ER dynamics whereby certain class XI myosins may have more influence over controlling cisternalization rather than tubulation.Biotechnology & Biological Sciences Research Council (BBSRC)Biology department at Texas A and M Universit

Student-Teacher Relationships: An Exploration of Student Motivation

The role that the student-teacher relationship has on students’ academic motivation was studied utilizing a phenomenology /hermeneutics technique with four 6th grade participants, three 8th grade participants, four 10th grade participants, and four 12th grade students. Results of the study suggested that student motivation is fostered when teacher support, teacher caring, teacher patience, extrinsic rewards, an emotional connection with the teacher, teacher expectations that are neither too high nor too low, and teacher motivation are present. Results also suggested when students witness other teachers harshly correcting other students, academic motivation is negatively affected. Finally, student maturity may impact motivation, as well as fun or interesting assignments, and a calm classroom atmosphere. Limitations and implications of this study were discussed

An analysis of tomato yield components in terms of genotypic and environmental effects

An analysis of tomato yield was made by partitioning yield into component parts. Yield was first broken down into the variables, number of fruits and fruit weight. The variable, number of fruits, was further partitioned into number of clusters and number of fruits per cluster. The experimental material consisted of six inbred lines and all possible F1\u27s from these lines (not including reciprocals). The parents collectively exhibited a tremendous range of expression for all characteristics. At the two extremes were the parents L. pimpinellifolium, with an average of 1,287 fruits per plant and an average fruit weight of 0.5 grams, and Matchless, a variety of L. esculentum, with a plant average of 16 fruits and an average fruit weight of 142.6 grams
