The Inner Quality Concept for food, based on life processes [PDF]

open access: yes, 2003
How can we adequately express the quality of food produced by organic agriculture? To answer this research question, we defined a concept of ‘inner quality’ (formerly called ‘vital quality’) based on the life processes growth and differentiation, and ...

Silencing Sl-EBF1 and Sl-EBF2 expression causes constitutive ethylene response phenotype, accelerated plant senescence, and fruit ripening in tomato [PDF]

open access: yes, 2010
The hormone ethylene regulates a wide range of plant developmental processes and EBF (EIN3-binding F-box) proteins were shown to negatively regulate the ethylene signalling pathway via mediating the degradation of EIN3/EIL proteins.

A molecular genetic perspective of reproductive development in grapevine [PDF]

open access: yes, 2008
The grapevine reproductive cycle has a number of unique features. Inflorescences develop from lateral meristems (anlagen) in latent buds during spring and summer and enter a dormant state at a very immature stage before completing development and ...

Towards identifying the dynamic cellular patterns underlying early Arabidopsis floral development [PDF]

open access: yes, 2013
A major challenge in developmental biology is to understand how multicellular tissues are organised into complex shapes. The various genetic, hormonal and mechanical events that drive morphogenesis must act by altering the properties of groups of cells ...

Environmental control of sepalness and petalness in waterilies

open access: yes, 2010
Existing models of perianth evolution are inadequate to explain morphological variation in tepals of early-divergent angiosperms as conventional concepts regarding the perianth include an unstated assumption that the characteristics of sepalness ...

The effects of shade on primocane fruiting blackberries in the field [PDF]

open access: yes, 2016
Primocane fruiting blackberry production in Arkansas is limited by heat during the flowering and early fruiting season. Shade could be used to delay flowering and fruiting to more favorable growth period.
