Both plants and animals make decisions in response to the environment to maximize their fitness. Plants use dormancy in seeds to move through time and space, and timing of the transition to germination is influenced by external cues, including temperature. Here, we report the presence of a decision-making center within the root tip of dormant seeds and demonstrate that it shares a similar configuration as some systems within the human brain.

Adansonia digitata L. (Malvaceae) is commonly known as baobab tree native to Africa. Baobab is a multi-purpose tree which offers protection and provides food, clothing and medicine as well as raw material for many useful items. The fruit pulp, seeds, leaves, flowers, roots, and bark of baobab are edible and they have been studied by scientists for their useful properties. The fruit pulp have very high vitamin C, calcium, phosphorus, carbohydrates, fibers, potassium, proteins and lipids content, which can be used in seasoning as an appetizer and also make juices.

Ethno medicinal survey was conducted in Satpura region with special reference to Chhindwara district of Madhya Pradesh. This district is a forest district,Chhindwara district, has acquired great importance because of its scenic beauty. Patalkot is a lovely landscape located at a depth of 1200-1500 feet in a valley, inhabited by Gonds, Bharia tribes who are entirely dependent on forest for medication. Information on 15 plant species belong to 15 genera and 14 families which are traditionally used as medicine to cure malaria was collected.

It is a well-known fact, that worldwide thousands of plant species are endangered and facing extinction with the
current trend of their exploitation and destruction. In recent years, there is a growing awareness concerning the impact
of temperature rise, industrialization, desertification and shift in the growing seasons of plants, loss of pollinators,
seed dispersers and increasing frequency of intense weather events such as drought, storms and floods making several valuable plants extinct.

Photosynthesis serves as a global stress sensor in plants, algae and cyanobacteria. In this overview, we focus on higher plants only. Although several structural and functional components of the photosynthetic apparatus are responsive to stress, photosystem II (PS II) and ribulose-1,5-bisphosphate carboxylase oxygenase

In 2008, Brazilian researchers embarked on a major effort to develop a comprehensive list of the nation's plants by 2010, the deadline for the goals set forth in the 1992 Convention on Biological Diversity, an international treaty on the conservation of flora and fauna worldwide.

Increases in annual mean temperature in the course of current climate change are expected to facilitate mass species migration towards higher altitudes and latitudes. However, this migration may be slowed, or even temporarily reversed, by infrequent and unpredictable episodes of low winter temperatures. Iran experienced a severe cold wave in January and February 2008, giving an opportunity to observe the effects on a large number of woody plant species, many growing further north than their natural ranges.
