Functional classification of olive pollen esterases

Pollen grains contain numerous hydrolytic enzymes, many of which are released upon contact with the stigma. Rejón et al. carry out for the first time...

Night temperature and source/sink effects in pepper ovaries

Pepper flower buds exposed to low night temperatures or a high source:sink ratio for as little as one week exhibit ovary swelling and resultant...

Photosynthetic thermotolerance and leaf traits

Little is known about photosynthetic thermotolerance (PT) of tropical and sub-tropical wild plants and its association with leaf phenology and persistence. Zhang et al. use...

How can a fungus be such a danger to ash?

The British government has reacted to the spread of Ash dieback by banning Ash imports to the UK. The Food and Environment Research Agency...
