The length of time a flower remained open (i.e., from anthesis to flower senescence) is called floral longevity. Floral longevity has been considered as one of the most important reproductive traits as it determines opportunities for pollen dispersal and capture of pollen by stigmas as well as has the potential to influence intra pollinator foraging and opportunities for geitonogamous self-pollination.
In a recent study a team of
researchers tested the potential for increased plant productivity and intrinsic water-use efficiency through the overexpression of inorganic carbon transporter B (ictB) in field-grown tobacco. However, their results showed no significant difference between the field-grown ictB expressing tobacco lines and wild-type.
As a part of the global biodiversity hotspots, the Taita Hills forests, located in Taita Taveta County in southeastern Kenya, forms the northernmost tip of the Eastern Arc Mountains. They are highly fragmented forests embedded in a human settlements and farms on the slopes and hilltops, resulting in the loss of 98% of the original forest cover on those mountains. Despite several botanical explorations and extensive floristic studies in these mountainous areas, there is a clear lack of sufficient literature on the flora and vegetation of the area. Through a joint effort, several field expeditions were carried out between 2015 and 2019, with an effort put to expand geographical coverage to areas where plant collections were previously scarce.
New insights into the evolutionary origins of unique African high mountain botanical diversity.
An international team of researchers, has successfully unravelled the genomes of 418 unique samples of rapeseed from across the globe to identify traits that breeders can use to improve crop yield.
Warm temperatures strongly enhance the regeneration of thale cress shoots, plant scientists have found. They have also uncovered the molecular mechanism behind this effect, which will help optimize the regeneration of plant cuttings for both plant-science research and horticulture.
Hybrid agricultural and horticultural crops can play an important role in supporting global food security. They produce higher yields and are often more resistant than non-hybrid varieties to diseases and climate stress. But for many crops, no hybrid varieties are available. Why is that?
