Climate change affects agricultural productivity worldwide. Increased prices of food commodities are the initial indication of drastic edible yield loss, which is expected to increase further due to global warming. This situation has compelled plant scientists to develop climate change-resilient crops, which can withstand broad-spectrum stresses such as drought, heat, cold, salinity, flood, submergence and pests, thus helping to deliver increased productivity. Genomics appears to be a promising tool for deciphering the stress responsiveness of crop species with adaptation traits or in wild relatives toward identifying underlying genes, alleles or quantitative trait loci. Molecular breeding approaches have proven helpful in enhancing the stress adaptation of crop plants, and recent advances in high-throughput sequencing and phenotyping platforms have transformed molecular breeding to genomics-assisted breeding (GAB). In view of this, the present review elaborates the progress and prospects of GAB for improving climate change resilience in crops, which is likely to play an ever increasing role in the effort to ensure global food security. © 2015 Kole, Muthamilarasan, Henry, Edwards, Sharma, Abberton, Batley, Bentley, Blakeney, Bryant, Cai, Cakir, Cseke, Cockram, de Oliveira, De Pace, Dempewolf, Ellison, Gepts, Greenland, Hall, Hori, Hughes, Humphreys, Iorizzo, Ismail, Marshall, Mayes, Nguyen, Ogbonnaya, Ortiz, Paterson, Simon, Tohme, Tuberosa, Valliyodan, Varshney, Wullschleger, Yano and Prasad.

A new plunannual species of Phaseolus has been found on the Pacific slope of central Costa Rica, in an intact wet forest of the San José province. It could belong to the section Brevilegumeni of the genus, and differs from P oligospermia by the round based leaflets with central permanent variegation, multi-flowered pseudoracemes with cup-shaped round primary bracts, flowers with white wings and light pinkish standard, slightly falcate pods with three lentil-like seeds. Its ecological niche is wetter and with a shorter dry season as compared to that of the latter species. Only two populations of the new taxon are known to date in this part of Costa Rica.
