(Pro)cambium formation and proliferation: two sides of the same coin?
نویسندگان
چکیده
The body of higher plants is usually pervaded by the (pro)cambium, a reticulate system of meristematic cells harboring the potential for producing vascular tissues at critical times and places. The (pro)cambium thereby provides the basis for the differential modulation of long-distance transport capacities and plant body stability. Distinct regulatory networks responsible for the initiation and proliferation of (pro)cambium cells have been identified. However, although a tight interaction between these networks can be expected, connections have been established only sporadically. Here we highlight recent discoveries of how (pro)cambium development is regulated and discuss possible interfaces between networks regulating two processes: (pro)cambium formation and cambium proliferation.

A HD‐ZIP III gene, PtrHB4, is required for interfascicular cambium development in Populus
Wood production is dependent on the activity of the vascular cambium, which develops from the fascicular and interfascicular cambia. However, little is known about the mechanisms controlling how the vascular cambium is developed in woody species. Here, we show that PtrHB4, belonging to the Populus HD-ZIP III family, plays a critical role in the process of vascular cambium development. PtrHB4 wa...
متن کاملAlternative Assessments and EFL Learner Autonomy
Alternative assessments have evolved from an epistemological change in education. They see assessment and instruction as two sides on the same coin which go hand in hand. The traditional roles of both teachers and learners are, consequently, modified which is essential for better language development. In this line, the present study aimed at comparing the effects of portfolio and journal writin...

متن کاملMultifaceted anti-amyloidogenic and pro-amyloidogenic effects of C-reactive protein and serum amyloid P component in vitro
C-reactive protein (CRP) and serum amyloid P component (SAP), two major classical pentraxins in humans, are soluble pattern recognition molecules that regulate the innate immune system, but their chaperone activities remain poorly understood. Here, we examined their effects on the amyloid fibril formation from Alzheimer's amyloid β (Aβ) (1-40) and on that from D76N β2-microglobulin (β2-m) which...
