Eucalypts are the world’s most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have made them a global renewable resource of fibre and energy. We sequenced and assembled >94% of the 640-megabase genome of Eucalyptus grandis. Of 36,376 predicted protein-coding genes, 34% occur in tandem duplications, the largest p...
The highly polymorphic S-locus receptor kinase (SRK) is the stigma determinant of specificity in the self-incompatibility response of the Brassicaceae. SRK spans the plasma membrane of stigma epidermal cells, and it is activated in an allele-specific manner on binding of its extracellular region (eSRK) to its cognate pollen coat-localized S-locus c...

Lectins are ubiquitous proteins that reversibly bind to specific carbohydrates and, thus, serve as readers of the sugar code. In photosynthetic organisms, lectin family proteins play important roles in capturing and releasing photosynthates via an endogenous lectin cycle. Often, lectin proteins consist of one or more lectin domains in combination w...
Chia (Salvia hispanica L.), now a popular superfood and a pseudocereal, is one of the richest sources of dietary nutrients such as protein, fiber, and polyunsaturated fatty acids (PUFAs).

The S-domain subfamily of receptor-like kinases (SDRLKs) in plants is poorly characterized. Most members of this subfamily are currently assigned gene function based on the S -locus Receptor Kinase from Brassica that acts as the female determinant of self-incompatibility (SI). However, Brassica like SI mechanisms does not exist in most plants. Thus...
हम सभी का खानपान से बेहद अंतरंग और प्राथमिक सम्बंध है. हम दुनिया के किसी भी हिस्से में हो, खानपान सम्बंधी चिंता हमारे मन में चाहे-अनचाहे बनी रहती है. बाज़ार से आटा, दाल, चावल, आलू, प्याज़, फल-सब्ज़ी, चाय, चीनी, कॉफ़ी आदि उठाते समय हम सोचते रहते हैं कि अमुक चीज़ स्वास्थ्य पर कैसा असर डालेगी; उसमें पौष्टिक तत्वों की मात्रा कितनी है; किसे विलास में और...

Biocuration plays a crucial role in building databases and complex systems-level platforms required for processing, annotating and analyzing ‘Big Data’ in biology. However, biocuration efforts cannot keep pace with a dramatic increase in the production of omics data; this presents one of the bottlenecks in genomics. In two pathway curation jamboree...

Seed formation is a plant’s long-term evolutionary strategy for surviving in extreme conditions of temperature and dehydration during long, extended periods. On arrival of the favorable season, seeds germinate and give rise to new plants. As an archetype seed retains elements of plant’s response to abiotic stresses and recovery from it. Here we rev...

This chapter describes the 5-locus cysteine-rich protein SCR, which is also known as SP11. It is identified in members of the Brassicaceae that exhibit self-incompatibility (SI). SCR is genetically and physically tightly linked to the gene for its receptor, the S-locus receptor kinase (SRK) gene. These two genes comprise the SI specificity-determin...
The genome of the cyanobacterium Synechocystis sp.
