Scientists have sequenced the oldest plant genome using 6,000-year-old seeds from a watermelon relative collected at an archaeological site in the Sahara Desert in Libya.

Hidden beneath the delicate, red skin and juicy flesh of a tomato is a wealth of nutrients and genetic makeup. With recent research on the first genome of a species in the tomatillo tribe (part of the tomato family), we now have a better idea of how this vital plant family came to be.
After a comprehensive study of plants across the United States, researchers have arrived at the unexpected conclusion that plants able to fix atmospheric nitrogen are most diverse in arid regions of the country. This finding runs counter to the prevailing assumption that nitrogen-fixers should be comparatively most diverse in environments where nitrogen in the soil is in limited supply.
Mt. Timolan Protected Landscape is one of the declared protected areas of the Philippines and is characterized by a variety of habitats. The presence of various microhabitats is reflected in the diversity of flora and fauna found there. However, limited information on its flora and fauna is available and biodiversity studies are scarce up until at present.
Biologist has discovered a previously unknown orchid species of the genus Rhipidoglossum in northeastern Tanzania. The new species was named Rhipidoglossum pareense, in keeping with its location in the South Pare Mountains.
Botanists suggest that the frilly lip of the white egret orchid evolved as a stabilizer for the hawkmoth while it pollinates the plant, resulting in better seed production.
In a new paper researchers concluded the eucalypt, currently known as Eucalyptus sp. Cattai, should be formally described, after confusion over whether it was a distinctive new species or a peculiar population resulting from the hybridization of two already described species.
Host-killing by hemiepiphytes is an endemic phenomenon in the tropics. Many fig species—keystone plants in tropical forests—have evolved the hemiepiphytic ecotype. However, the benefits and adaptive strategies of their special life history remain poorly understood.
Land plants evolved 470 million years ago from algae and have since reshaped our world. Throughout their evolution, ferns have undergone a series of changes that have helped them survive on land. For the first time, researchers have characterized the genome arrangement of tree ferns, which sheds new insight into how ferns evolved.
Violets reproduce both sexually, through cross-pollination of the showy flowers we’re familiar with; and asexually, by self-seeding of less noticeable flowers that remain hidden near the base of the plant. This is called “mixed mating.” Although environmental factors drive how much a plant reproduces sexually or asexually, no study had previously looked at the impact of climate change on mixed mating.
