Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...

Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. See also the Commentary on this article by May & Nagy, 252: 525–527. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions ...

A role for vegetation phenology in shaping patterns of ecosystem sensitivity to drought
Examples of vegetation phenology during drought. Summary Phenology, as the study of the timing and rhythms of vegetation activity, has traditionally emphasized trends in phenological responses to gradual climate change. Consequently, we lack understanding of phenological responses to concurrent increases in the frequency and intensity of climate ...

Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

Upstream horizontal mergers, bargaining, vertical contracts [PDF]
Contrary to the seminal paper of Horn and Wolinsky (1988), we demonstrate that upstream firms, which sell their products to competing downstream firms, do not always have incentives to merge horizontally. In particular, we show that when bargaining takes
